# Struct ipworkspgp::PFileMailer The PFileMailer struct is used to send encrypted and/or signed plaintext-formatted emails, with any attachments, using OpenPGP. ## Syntax ```text ipworkspgp::PFileMailer ``` ## Remarks The PFileMailer struct offers an easy-to-use interface: you can send an OpenPGP signed and encrypted message using the PSMTP struct by calling the [encrypt](#encrypt-method-pfilemailer-struct), [sign](#sign-method-pfilemailer-struct), and [sign_and_encrypt](#sign_and_encrypt-method-pfilemailer-struct) methods. Additionally, it enables you to create messages bound for multiple recipients with different keys, simultaneously encrypt and compress with the most popular compression algorithms, and control other aspects such as the encrypting algorithm. **Construct the Message** To begin specify common email properties such as [send_to](#send_to-property-pfilemailer-struct), [cc](#cc-property-pfilemailer-struct), [b_cc](#b_cc-property-pfilemailer-struct), [subject](#subject-property-pfilemailer-struct), and [message_text](#message_text-property-pfilemailer-struct). Connection information is specified by setting [mail_server](#mail_server-property-pfilemailer-struct) and [mail_port](#mail_port-property-pfilemailer-struct). **Sign** To sign a message specify a recipient key using the **Key*** properties. For instance: ```text PFileMailer1.KeyCount = 1 PFileMailer1.KeyKeyring(0) = "c:\my_keyring_dir" PFileMailer1.KeyUserId(0) = "sender@nsoftware.com" PFileMailer1.KeyPassphrase(0) = "password" ``` The specified private key will be used to sign the message when [sign](#sign-method-pfilemailer-struct) is called. **Encrypt** To encrypt a message specify a recipient key using the **RecipientKey*** properties. For instance: ```text PFileMailer1.RecipientKeyCount = 1 PFileMailer1.RecipientKeyKeyring(0) = "c:\my_keyring_dir" PFileMailer1.RecipientKeyUserId(0) = "recipient@nsoftware.com" ``` The specified public key will be used to encrypt the message when [encrypt](#encrypt-method-pfilemailer-struct) is called. **Sign and Encrypt** To sign and encrypt a message in one step call [sign_and_encrypt](#sign_and_encrypt-method-pfilemailer-struct). The message will be signed with the private keys specified in the **Key*** properties and encrypted with the public keys defined in the **RecipientKeys*** properties. **Add Attachments** To add attachments simply call [add_attachment](#add_attachment-method-pfilemailer-struct). The [ProcessAttachments](#ProcessAttachments) setting specifies whether attachments are also encrypted and signed. **Send** Call the [send](#send-method-pfilemailer-struct) method once the necessary properties have been set for each recipient. ### Object Lifetime The *new()* method returns a mutable reference to a struct instance. The object itself is kept in the global list maintained by IPWorksPGP. Due to this, the PFileMailer struct cannot be disposed of automatically. Please, call the *dispose(&mut; self)* method of PFileMailer when you have finished using the instance. ## Property List *The following is the full list of the properties of the struct with short descriptions.

When a key is loaded this property is populated with the user Id associated with the key. This property may be set to load a key from the [key_keyring](#PFileMailer_p_KeyKeyring). When this property is set the struct will search the [key_keyring](#PFileMailer_p_KeyKeyring) for a key associated with the UserId specified. When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and [key_other_user_ids](#KeyMgr_p_KeyOtherUserIds) after loading the key. The *UserId* format is: ```text FirstName LastName (Comment) ``` Not all values are required when selecting or generating a key, but at least FirstName or Email are required. Note that for OpenPGP v6, a key may be created with or without a *UserId*, as the field is optional. If a key was created without a *UserId*, the key's *Fingerprint* can be used as its identifier instead. When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The struct will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP struct's on_recipient_info event. The *KeyIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [KeyCount](#key_count-property-pfilemailer-struct) property. ## Data Type String # key_id property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The hex-encoded, 4-byte or 8-byte key Id. ## Syntax *Rust Syntax* ```text fn key_id(&self , KeyIndex : i32) -> Result fn set_key_id(&self, KeyIndex : i32, value : &str) -> Option fn set_key_id_ref(&self, KeyIndex : i32, value : &String) -> Option ``` ## Default Value "" ## Remarks The hex-encoded, 4-byte or 8-byte key Id. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's *Fingerprint*. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's *Fingerprint* instead. For instance: ```text 5E70662EA810E768 ``` When a key is loaded, this property is populated with the Id associated with the key. This property may be set to load a key from the [key_keyring](#PFileMailer_p_KeyKeyring). When this property is set the struct will search the [key_keyring](#PFileMailer_p_KeyKeyring) for a key associated with the Id specified. The KeyIdLength setting may be set to control the length of the returned key Id. NOTE: It is recommended to use the [key_fingerprint](#key_fingerprint-property-pfilemailer-struct) property when loading a key from the [key_keyring](#PFileMailer_p_KeyKeyring), as it is possible for different keys to have the same Id. The *KeyIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [KeyCount](#key_count-property-pfilemailer-struct) property. ## Data Type String # key_fingerprint property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The hex-encoded, 20-byte fingerprint of the key. ## Syntax *Rust Syntax* ```text fn key_fingerprint(&self , KeyIndex : i32) -> Result fn set_key_fingerprint(&self, KeyIndex : i32, value : &str) -> Option fn set_key_fingerprint_ref(&self, KeyIndex : i32, value : &String) -> Option ``` ## Default Value "" ## Remarks The hex-encoded, 20-byte fingerprint of the key. When a key is loaded, this property is populated with the Fingerprint associated with the key. This property may be set to load a key from the [key_keyring](#PFileMailer_p_KeyKeyring). When this property is set the struct will search the [key_keyring](#PFileMailer_p_KeyKeyring) for a key associated with the Fingerprint specified. This is in the form: ```text 5E70662EA810E768391A2FE8F7B7D49C89C9D7B1 ``` The *KeyIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [KeyCount](#key_count-property-pfilemailer-struct) property. ## Data Type String # key_encoded property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The key. ## Syntax *Rust Syntax* ```text fn key_encoded(&self , KeyIndex : i32) -> Result, IPWorksPGPError> fn set_key_encoded(&self, KeyIndex : i32, value : Vec) -> Option fn set_key_encoded_ref(&self, KeyIndex : i32, value : &[u8]) -> Option ``` ## Default Value "" ## Remarks The key. This property can be used to assign a specific key. The [key_fingerprint](#key_fingerprint-property-pfilemailer-struct), [key_id](#key_id-property-pfilemailer-struct), and [key_user_id](#key_user_id-property-pfilemailer-struct) properties may also be used to specify a key. The *KeyIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [KeyCount](#key_count-property-pfilemailer-struct) property. ## Data Type Vec # last_reply property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property indicates the last reply received from the server. ## Syntax *Rust Syntax* ```text fn last_reply(&self ) -> Result ``` ## Default Value "" ## Remarks This property indicates the last reply received from the server. It can be used for informational purposes. The same information and more also can be retrieved through the [on_pi_trail](#on_pi_trail-event-pfilemailer-struct) event. This property is read-only. ## Data Type String # local_host property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The name of the local host or user-assigned IP interface through which connections are initiated or accepted. ## Syntax *Rust Syntax* ```text fn local_host(&self ) -> Result fn set_local_host(&self, value : &str) -> Option fn set_local_host_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks This property contains the name of the local host as obtained by the *gethostname()* system call, or if the user has assigned an IP address, the value of that address. In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the struct initiate connections (or accept in the case of server structs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used. If the struct is connected, the local_host property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface). NOTE: local_host is not persistent. You must always set it in code, and never in the property window. ## Data Type String # mail_port property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property includes the server port for SMTP (default 25). ## Syntax *Rust Syntax* ```text fn mail_port(&self ) -> Result fn set_mail_port(&self, value : i32) -> Option ``` ## Default Value 25 ## Remarks This property contains the server port for SMTP (default 25). A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error. For an implicit Secure Sockets Layer (SSL), use port 465 (please refer to the [ssl_start_mode](#ssl_start_mode-property-pfilemailer-struct) property for more information). ## Data Type i32 # mail_server property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property includes the name or address of a mail server (mail relay). ## Syntax *Rust Syntax* ```text fn mail_server(&self ) -> Result fn set_mail_server(&self, value : &str) -> Option fn set_mail_server_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks This property specifies the IP address (IP number in dotted internet format) or domain name for a mail relay through which messages will be routed. It is set before a connection is attempted and cannot be changed once a connection is in progress. The current version of the struct does not provide a default value for the mail relay. You must provide a host name yourself. Generally, any internet host with an SMTP server will suffice (e.g., a UNIX host), but it is preferable to select a mail_server that is close to the machine sending mail. If this property is set to a domain name, a DNS request is initiated. Upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned. If the struct is configured to use a *SOCKS* firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution. ## Data Type String # message_date property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property includes the date of the mail message (optional). ## Syntax *Rust Syntax* ```text fn message_date(&self ) -> Result fn set_message_date(&self, value : &str) -> Option fn set_message_date_ref(&self, value : &String) -> Option ``` ## Default Value "*" ## Remarks If this property contains a nonempty string, then a *Date* SMTP header is created and attached to the message. If it is an empty string, then the date information is added by the mail relay(s) the message goes through. Special case: If this property is set to the special value "*", a *Date* SMTP header reflecting the current date and time is generated when message_headers is computed and the message is sent. This is the default behavior of the struct RFC 822 contains detailed date format specifications. An example of a valid date is "Fri, 1 Mar 96 21:24:52 EST". ## Data Type String # message_id property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property includes the message identifier for the message. ## Syntax *Rust Syntax* ```text fn message_id(&self ) -> Result fn set_message_id(&self, value : &str) -> Option fn set_message_id_ref(&self, value : &String) -> Option ``` ## Default Value "*" ## Remarks This property contains the message identifier for the message. When set, the value of message_id is used as the Message-Id header value of the message. A special value of "*" will automatically generate a random unique identifier for the message. ## Data Type String # message_recipient_count property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The number of records in the MessageRecipient arrays. ## Syntax *Rust Syntax* ```text fn message_recipient_count(&self ) -> Result fn set_message_recipient_count(&self, value : i32) -> Option ``` ## Default Value 0 ## Remarks This property controls the size of the following arrays: - [message_recipient_address](#message_recipient_address-property-pfilemailer-struct) - [message_recipient_name](#message_recipient_name-property-pfilemailer-struct) - [message_recipient_options](#message_recipient_options-property-pfilemailer-struct) - [message_recipient_type](#message_recipient_type-property-pfilemailer-struct) The array indices start at *0* and end at *message_recipient_count - 1*. ## Data Type i32 # message_recipient_address property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property contains the email address of the recipient. ## Syntax *Rust Syntax* ```text fn message_recipient_address(&self , RecipientIndex : i32) -> Result fn set_message_recipient_address(&self, RecipientIndex : i32, value : &str) -> Option fn set_message_recipient_address_ref(&self, RecipientIndex : i32, value : &String) -> Option ``` ## Default Value "" ## Remarks This property contains the email address of the recipient. The *RecipientIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [MessageRecipientCount](#message_recipient_count-property-pfilemailer-struct) property. ## Data Type String # message_recipient_name property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property contains the name of the recipient. ## Syntax *Rust Syntax* ```text fn message_recipient_name(&self , RecipientIndex : i32) -> Result fn set_message_recipient_name(&self, RecipientIndex : i32, value : &str) -> Option fn set_message_recipient_name_ref(&self, RecipientIndex : i32, value : &String) -> Option ``` ## Default Value "" ## Remarks This property contains the name of the recipient.

This property is mapped to the *redirect_uri* parameter when making a request to the authorization server. Typically, this is automatically set by the struct when using the embedded web server. If the OAuthWebServerPort or OAuthWebServerHost configuration settings is set, then this property should be set to match. If using the Web client profile, this should be set to the place where the authorization code will be parsed out of the response after the user finishes authorizing. ## Data Type String # o_auth_server_auth_url property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The URL of the authorization server. ## Syntax *Rust Syntax* ```text fn o_auth_server_auth_url(&self ) -> Result fn set_o_auth_server_auth_url(&self, value : &str) -> Option fn set_o_auth_server_auth_url_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks The URL of the authorization server. ## Data Type String # o_auth_server_token_url property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The URL of the token server used to obtain the access token. ## Syntax *Rust Syntax* ```text fn o_auth_server_token_url(&self ) -> Result fn set_o_auth_server_token_url(&self, value : &str) -> Option fn set_o_auth_server_token_url_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks The URL of the token server used to obtain the access token. ## Data Type String # other_headers property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property includes an RFC 822-compliant string consisting of extra headers. ## Syntax *Rust Syntax* ```text fn other_headers(&self ) -> Result fn set_other_headers(&self, value : &str) -> Option fn set_other_headers_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks This property contains a string of headers to be appended to the message headers created from other properties like [send_to](#send_to-property-pfilemailer-struct), [subject](#subject-property-pfilemailer-struct), and so on. The headers must be of the format "header: value" as specified in RFC 822. Header lines should be separated by CRLF (*"\r\n"*) . Use this property with caution. If this property contains invalid headers, message delivery might not be successful. This property is useful for extending the functionality of the struct. A good example is delivery of MIME-encoded messages. Special case: If this property starts with an empty line (CRLF), then the value of this property is used instead of the normally computed message headers. **Example. Sending an Email with an Additional Header:** ```text component.MailServer = "MyServer"; component.From = "me@server.com"; component.SendTo = "recipient@server.com"; component.Subject = "My Subject"; component.MessageText = "This is the message body."; component.OtherHeaders = "HeaderName: HeaderValue"; component.Send(); ``` ## Data Type String # password property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property includes a password for logon to the MailServer . ## Syntax *Rust Syntax* ```text fn password(&self ) -> Result fn set_password(&self, value : &str) -> Option fn set_password_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks If this property is set to a nonempty string, then when connecting to the [mail_server](#mail_server-property-pfilemailer-struct) an AUTH or CRAM-MD5 (depending on the value of [auth_mechanism](#auth_mechanism-property-pfilemailer-struct)) command is sent to provide authentication information for the user. ## Data Type String # priority property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property includes the priority of the mail message (optional). ## Syntax *Rust Syntax* ```text fn priority(&self ) -> Result fn set_priority(&self, value : i32) -> Option ``` ## Possible Values ```text 0 // Unspecified1 // Normal2 // Urgent3 // NonUrgent ``` ## Default Value 0 ## Remarks When this property is set, a priority header will be added to the message.

When this property is set the struct will search the [recipient_key_keyring](#recipient_key_keyring-property-pfilemailer-struct) for a key associated with the UserId specified. When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and [key_other_user_ids](#KeyMgr_p_KeyOtherUserIds) after loading the key. The *UserId* format is: ```text FirstName LastName (Comment) ``` Not all values are required when selecting or generating a key, but at least FirstName or Email are required. Note that for OpenPGP v6, a key may be created with or without a *UserId*, as the field is optional. If a key was created without a *UserId*, the key's *Fingerprint* can be used as its identifier instead. When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The struct will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP struct's on_recipient_info event. The *RecipientKeyIndex* parameter specifies the index of the item in the array.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject. If a matching certificate is found, the property is set to the full subject of the matching certificate. If an exact match is not found, the store is searched for subjects containing the value of the property. If a match is still not found, the property is set to an empty string, and no certificate is selected. The special value "*" picks a random certificate in the certificate store. The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=example@email.com". Common fields and their meanings are as follows: | Field | Meaning | | --- | --- | | CN | Common Name. This is commonly a hostname like www.server.com. | | O | Organization | | OU | Organizational Unit | | L | Locality | | S | State | | C | Country | | E | Email Address | If a field value contains a comma, it must be quoted. This property is read-only. ## Data Type String # ssl_server_cert_encoded property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The certificate (PEM/Base64 encoded). ## Syntax *Rust Syntax* ```text fn ssl_server_cert_encoded(&self ) -> Result, IPWorksPGPError> ``` ## Default Value "" ## Remarks The certificate (PEM/Base64 encoded).

The [ssl_server_cert_store](#ssl_server_cert_store-property-pfilemailer-struct) and [ssl_server_cert_subject](#ssl_server_cert_subject-property-pfilemailer-struct) properties also may be used to specify a certificate. When [ssl_server_cert_encoded](#ssl_server_cert_encoded-property-pfilemailer-struct) is set, a search is initiated in the current [ssl_server_cert_store](#ssl_server_cert_store-property-pfilemailer-struct) for the private key of the certificate. If the key is found, [ssl_server_cert_subject](#ssl_server_cert_subject-property-pfilemailer-struct) is updated to reflect the full subject of the selected certificate; otherwise, [ssl_server_cert_subject](#ssl_server_cert_subject-property-pfilemailer-struct) is set to an empty string. This property is read-only. ## Data Type Vec # ssl_start_mode property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property determines how the struct starts the Secure Sockets Layer (SSL) negotiation. ## Syntax *Rust Syntax* ```text fn ssl_start_mode(&self ) -> Result fn set_ssl_start_mode(&self, value : i32) -> Option ``` ## Possible Values ```text 0 // Automatic1 // Implicit2 // Explicit3 // None ``` ## Default Value 3 ## Remarks The ssl_start_mode property may have one of the following values: | | | | --- | --- | | 0 (sslAutomatic) | If the remote port is set to the standard plaintext port of the protocol (where applicable), the struct will behave the same as if ssl_start_mode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit). | | 1 (sslImplicit) | The SSL negotiation will start immediately after the connection is established. | | 2 (sslExplicit) | The struct will first connect in plaintext, and then will explicitly start SSL negotiation through a protocol command such as STARTTLS. | | 3 (sslNone - default) | No SSL negotiation; no SSL security. All communication will be in plaintext mode. | ## Data Type i32 # subject property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property includes the subject of the mail message (optional). ## Syntax *Rust Syntax* ```text fn subject(&self ) -> Result fn set_subject(&self, value : &str) -> Option fn set_subject_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks The string in this property is sent with a *Subject* SMTP header to the mail recipient. If the resulting header is longer than [MaxHeaderLength](#MaxHeaderLength), then it is folded according to RFC 822 specifications. ## Data Type String # timeout property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The timeout for the struct. ## Syntax *Rust Syntax* ```text fn timeout(&self ) -> Result fn set_timeout(&self, value : i32) -> Option ``` ## Default Value 60 ## Remarks If the timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered. If timeout is set to a positive value, the struct will wait for the operation to complete before returning control. The struct will use [do_events](#do_events-method-pfilemailer-struct) to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive. If timeout expires, and the operation is not yet complete, the struct fails with an error. NOTE: By default, all timeouts are *inactivity timeouts*, that is, the timeout period is extended by timeout seconds when any amount of data is successfully sent or received. The default value for the timeout property is 60 seconds. ## Data Type i32 # user property ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This property includes the user identifier needed to log in as in the MailServer . ## Syntax *Rust Syntax* ```text fn user(&self ) -> Result fn set_user(&self, value : &str) -> Option fn set_user_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks If this property is set to a nonempty string, then when connecting to the [mail_server](#mail_server-property-pfilemailer-struct) an *AUTH* or *CRAM-MD5* (depending on the value of [auth_mechanism](#auth_mechanism-property-pfilemailer-struct)) command is sent to provide authentication information for the user. ## Data Type String # add_attachment method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This adds FileName as an attachment. ## Syntax *Rust Syntax* ```text fn add_attachment(&self, file_name : &str) -> Result<(), IPWorksPGPError> ``` ## Remarks This method adds the file name as an attachment. The full list of attachments is contained in the attachments property. **Example 1: Adding an Attachment** ```text component.AddAttachment("C:\file1.zip"); component.AddAttachment("C:\file2.zip"); component.Send(); ``` **Example 3: Using an Attachments Array** ```text component.AttachmentCount = 1; component.AttachmentName(0) = "name"; component.AttachmentFile(0) = "C:\file.txt"; ``` # config method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Sets or retrieves a configuration setting. ## Syntax *Rust Syntax* ```text fn config(&self, configuration_string : &str) -> Result ``` ## Remarks config is a generic method available in every struct. It is used to set and retrieve [configuration settings](#config-settings-pfilemailer-struct) for the struct. These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these *internal properties* is provided through the config method. To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter). To read (query) the value of a [configuration setting](#config-settings-pfilemailer-struct), you must call *Config("PROPERTY")*. The value will be returned as a string. # connect method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This method connects to the mail relay and sends the SMTP HELO command. ## Syntax *Rust Syntax* ```text fn connect(&self) -> Result<(), IPWorksPGPError> ``` ## Remarks This method connects to the mail relay and sends the SMTP *HELO* command, thus preparing to send messages. Any number of messages can later be sent using the [send](#send-method-pfilemailer-struct) method. **Example. Connecting and Sending an Email:** ```text control.MailServer = "MyServer" control.From = "me@server.com" control.SendTo = "recipient@server.com" control.Subject = "My Subject" control.MessageText = "This is the message body" control.Connect() control.Send() control.Disconnect() ``` # disconnect method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This method disconnects from the SMTP server. ## Syntax *Rust Syntax* ```text fn disconnect(&self) -> Result<(), IPWorksPGPError> ``` ## Remarks This method disconnects from the mail relay. # do_events method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This method processes events from the internal message queue. ## Syntax *Rust Syntax* ```text fn do_events(&self) -> Result<(), IPWorksPGPError> ``` ## Remarks When do_events is called, the struct processes any available events. If no events are available, it waits for a preset period of time, and then returns. # encrypt method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Encrypts the message. ## Syntax *Rust Syntax* ```text fn encrypt(&self) -> Result<(), IPWorksPGPError> ``` ## Remarks This method encrypts the specified message. The message is encrypted with the public keys specified in recipient_keys. When encrypting, the following properties may be used to further configure the struct: - [compression_method](#compression_method-property-pfilemailer-struct) - [encrypting_algorithm](#encrypting_algorithm-property-pfilemailer-struct) # interrupt method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This method interrupts the current method. ## Syntax *Rust Syntax* ```text fn interrupt(&self) -> Result<(), IPWorksPGPError> ``` ## Remarks If there is no method in progress, interrupt simply returns, doing nothing. # process_queue method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This method sends the messages that previously have been queued into QueueDir . ## Syntax *Rust Syntax* ```text fn process_queue(&self, queue_dir : &str) -> Result<(), IPWorksPGPError> ``` ## Remarks This method sends the messages that previously have been queued into *queue_dir*. The [on_pi_trail](#on_pi_trail-event-pfilemailer-struct) event shows the interaction with the server as messages are processed. This method looks in the directory for files with the extension ".queued" and starts processing them. When processing starts, the file extension is changed to ".sending". If an error happens at this stage, the sending process is aborted, and the file extension is changed to ".failed". If the file is successfully sent, the file is normally deleted, unless the [KeepQueue](#KeepQueue) configuration setting is set to True, in which case the file extension is instead changed to ".sent" and the queue file is not deleted. # queue method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This method queues the message into QueueDir . ## Syntax *Rust Syntax* ```text fn queue(&self, queue_dir : &str) -> Result ``` ## Remarks This method queues the message into *queue_dir*. The message is queued into a unique file into the directory *queue_dir* for future processing. *queue_dir* must already exist, or an error will be generated. Alternatively, *queue_dir* may be set to "*" to return the result as a string instead of writing it to a file. This method returns the name of the unique queue file created in *queue_dir*. The file extension is ".queued". Please refer to the [process_queue](#process_queue-method-pfilemailer-struct) method for more information on email queue processing. # reset_headers method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This method resets all the message headers to empty. ## Syntax *Rust Syntax* ```text fn reset_headers(&self) -> Result<(), IPWorksPGPError> ``` ## Remarks This method resets all the message headers to "" (empty string). Use this method before creating a new message, so that headers from the previous message are not carried over to the next one. # send method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This sends the current message and the MIME-encoded attachment. ## Syntax *Rust Syntax* ```text fn send(&self) -> Result<(), IPWorksPGPError> ``` ## Remarks This method sends the current message and the MIME-encoded attachment. If the struct is not connected to the mail relay, a connection is created, the message is sent, and then the connection is closed unless an error occurs. If the struct is already connected (by use of the [connect](#connect-method-pfilemailer-struct) method), the connection will remain open after the message is sent. To disconnect, call the [disconnect](#disconnect-method-pfilemailer-struct) method. # send_command method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This method sends the exact command directly to the server. ## Syntax *Rust Syntax* ```text fn send_command(&self, command : &str) -> Result<(), IPWorksPGPError> ``` ## Remarks This method sends the command specified by *command* to the server exactly as it is provided. Use this method to send additional or custom commands directly to the server. After calling this method, check the [last_reply](#last_reply-property-pfilemailer-struct) property or monitor the [on_pi_trail](#on_pi_trail-event-pfilemailer-struct) event to obtain the server's response. # sign method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Signs the message. ## Syntax *Rust Syntax* ```text fn sign(&self) -> Result<(), IPWorksPGPError> ``` ## Remarks This method signs the specified message. The message is signed with the private key specified in keys. When signing, the following properties may be used to further configure the struct: - [ClearSignature](#ClearSignature) - [signing_algorithm](#signing_algorithm-property-pfilemailer-struct) # sign_and_encrypt method ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Signs and encrypts the current message. ## Syntax *Rust Syntax* ```text fn sign_and_encrypt(&self) -> Result<(), IPWorksPGPError> ``` ## Remarks This method signs and encrypts the specified message. The message is encrypted with the public keys specified in recipient_keys and signed with the private key specified in keys. When encrypting, the following properties may be used to further configure the struct: - [compression_method](#compression_method-property-pfilemailer-struct) - [encrypting_algorithm](#encrypting_algorithm-property-pfilemailer-struct) When signing, the following properties may be used to further configure the struct: - [ClearSignature](#ClearSignature) - [signing_algorithm](#signing_algorithm-property-pfilemailer-struct) # on_connection_status event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Fired to indicate changes in the connection state. ## Syntax *Rust Syntax* ```text // PFileMailerConnectionStatusEventArgs carries the PFileMailer ConnectionStatus event's parameters. pub struct PFileMailerConnectionStatusEventArgs { fn connection_event(&self) -> &String fn status_code(&self) -> i32 fn description(&self) -> &String } // PFileMailerConnectionStatusEvent defines the signature of the PFileMailer ConnectionStatus event's handler function. pub trait PFileMailerConnectionStatusEvent { fn on_connection_status(&self, sender : PFileMailer, e : &mut PFileMailerConnectionStatusEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_connection_status(&self) -> &'a dyn PFileMailerConnectionStatusEvent; pub fn set_on_connection_status(&mut self, value : &'a dyn PFileMailerConnectionStatusEvent); ... } ``` ## Remarks This event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake. The *connection_event* parameter indicates the type of connection event. Values may include the following: | | | | --- | --- | | | Firewall connection complete. | | | Secure Sockets Layer (SSL) or S/Shell handshake complete (where applicable). | | | Remote host connection complete. | | | Remote host disconnected. | | | SSL or S/Shell connection broken. | | | Firewall host disconnected. | *status_code* has the error code returned by the Transmission Control Protocol (TCP)/IP stack. *description* contains a description of this code. The value of *status_code* is equal to the value of the error. # on_end_transfer event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This event is fired when the message text completes transferring. ## Syntax *Rust Syntax* ```text // PFileMailerEndTransferEventArgs carries the PFileMailer EndTransfer event's parameters. pub struct PFileMailerEndTransferEventArgs { fn direction(&self) -> i32 } // PFileMailerEndTransferEvent defines the signature of the PFileMailer EndTransfer event's handler function. pub trait PFileMailerEndTransferEvent { fn on_end_transfer(&self, sender : PFileMailer, e : &mut PFileMailerEndTransferEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_end_transfer(&self) -> &'a dyn PFileMailerEndTransferEvent; pub fn set_on_end_transfer(&mut self, value : &'a dyn PFileMailerEndTransferEvent); ... } ``` ## Remarks If [message_text](#message_text-property-pfilemailer-struct) is not empty, the on_end_transfer event is fired when the [message_text](#message_text-property-pfilemailer-struct) finishes transferring from the local host to the [mail_server](#mail_server-property-pfilemailer-struct). If [message_text](#message_text-property-pfilemailer-struct) is empty, the event is not fired. If a file is attached to the [message_text](#message_text-property-pfilemailer-struct) via the attached_file property, then on_end_transfer fires again when the file finishes transferring. For more information, go to the description of the attached_file property. The *Direction* parameter shows whether the client (0) or the server (1) is sending the data. # on_error event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Fired when information is available about errors during data delivery. ## Syntax *Rust Syntax* ```text // PFileMailerErrorEventArgs carries the PFileMailer Error event's parameters. pub struct PFileMailerErrorEventArgs { fn error_code(&self) -> i32 fn description(&self) -> &String } // PFileMailerErrorEvent defines the signature of the PFileMailer Error event's handler function. pub trait PFileMailerErrorEvent { fn on_error(&self, sender : PFileMailer, e : &mut PFileMailerErrorEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_error(&self) -> &'a dyn PFileMailerErrorEvent; pub fn set_on_error(&mut self, value : &'a dyn PFileMailerErrorEvent); ... } ``` ## Remarks The on_error event is fired in case of exceptional conditions during message processing. Normally the struct fails with an error. The *error_code* parameter contains an error code, and the *description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-pfilemailer-struct) section. # on_key_passphrase event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Fired if the passphrase of current key is incorrect or empty. ## Syntax *Rust Syntax* ```text // PFileMailerKeyPassphraseEventArgs carries the PFileMailer KeyPassphrase event's parameters. pub struct PFileMailerKeyPassphraseEventArgs { fn user_id(&self) -> &String fn key_id(&self) -> &String fn fingerprint(&self) -> &String fn passphrase(&self) -> &String fn set_passphrase(&self, value : &str) fn set_passphrase_ref(&self, value : &String) } // PFileMailerKeyPassphraseEvent defines the signature of the PFileMailer KeyPassphrase event's handler function. pub trait PFileMailerKeyPassphraseEvent { fn on_key_passphrase(&self, sender : PFileMailer, e : &mut PFileMailerKeyPassphraseEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_key_passphrase(&self) -> &'a dyn PFileMailerKeyPassphraseEvent; pub fn set_on_key_passphrase(&mut self, value : &'a dyn PFileMailerKeyPassphraseEvent); ... } ``` ## Remarks This event fires when the passphrase for the key is required. The passphrase must be specified before operations requiring the secret key are attempted. The passphrase may be supplied by setting the *Passphrase* parameter in this event, or by specifying the [key_passphrase](#key_passphrase-property-pfilemailer-struct) property before attempting the operation. The passphrase is required when using the following methods in KeyMgr: - add_user_id - sign_user_id - change_expiration_date - change_passphrase When using the OpenPGP struct, or an email-based struct, the following methods require a passphrase for the key: - decrypt - [sign](#sign-method-pfilemailer-struct) - [sign_and_encrypt](#sign_and_encrypt-method-pfilemailer-struct) *UserId* holds the user Id of the key the passphrase is required for. The *UserId* format is: ```text FirstName LastName (Comment) ``` Not all values are required when selecting or generating a key, but at least FirstName or Email are required. Note that for OpenPGP v6, a key may be created with or without a *UserId*, as the field is optional. If a key was created without a *UserId*, the key's *Fingerprint* can be used as its identifier instead. *KeyId* is the hex-encoded, 4-byte or 8-byte Id of the key the passphrase is required for. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's *Fingerprint*. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's *Fingerprint* instead. For instance: ```text 5E70662EA810E768 ``` *Fingerprint* holds the hex-encoded, 20-byte fingerprint of the key the passphrase is required for. This is in the form: ```text 5E70662EA810E768391A2FE8F7B7D49C89C9D7B1 ``` # on_launch_browser event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Fires before launching a browser with the authorization URL. ## Syntax *Rust Syntax* ```text // PFileMailerLaunchBrowserEventArgs carries the PFileMailer LaunchBrowser event's parameters. pub struct PFileMailerLaunchBrowserEventArgs { fn url(&self) -> &String fn set_url(&self, value : &str) fn set_url_ref(&self, value : &String) fn command(&self) -> &String fn set_command(&self, value : &str) fn set_command_ref(&self, value : &String) } // PFileMailerLaunchBrowserEvent defines the signature of the PFileMailer LaunchBrowser event's handler function. pub trait PFileMailerLaunchBrowserEvent { fn on_launch_browser(&self, sender : PFileMailer, e : &mut PFileMailerLaunchBrowserEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_launch_browser(&self) -> &'a dyn PFileMailerLaunchBrowserEvent; pub fn set_on_launch_browser(&mut self, value : &'a dyn PFileMailerLaunchBrowserEvent); ... } ``` ## Remarks When the client_profile property is set to ocpApplication and get_authorization is called, the struct will fire this event with the *command*, which will be executed by the struct. The *url* parameter will be the authorization URL that the user will be directed to authenticate. Within this event, you may override the current value of either *command* or *url* and provide your own value. If *command* is set to an empty string, the struct will not attempt to launch the browser and instead you will be responsible for directing the user to the authorization URL specified by the URL parameter. If *command* is not empty, the URL will be appended to the end. In Windows, ShellExecute is used to execute *command*, which limits the verbs available for use in *command* to: - edit - explore - find - open - print # on_log event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Fired once for each log message. ## Syntax *Rust Syntax* ```text // PFileMailerLogEventArgs carries the PFileMailer Log event's parameters. pub struct PFileMailerLogEventArgs { fn log_level(&self) -> i32 fn message(&self) -> &String fn log_type(&self) -> &String } // PFileMailerLogEvent defines the signature of the PFileMailer Log event's handler function. pub trait PFileMailerLogEvent { fn on_log(&self, sender : PFileMailer, e : &mut PFileMailerLogEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_log(&self) -> &'a dyn PFileMailerLogEvent; pub fn set_on_log(&mut self, value : &'a dyn PFileMailerLogEvent); ... } ``` ## Remarks This event is fired once for each log message generated by the struct. The verbosity is controlled by the [LogLevel](#LogLevel) setting. *log_level* indicates the level of message. Possible values are as follows: | | | | --- | --- | | 0 (None) | No events are logged. | | 1 (Info - default) | Informational events are logged. | | 2 (Verbose) | Detailed data are logged. | | 3 (Debug) | Debug data are logged. | The value 1 (Info) logs basic information, including the URL, HTTP version, and status details. The value 2 (Verbose) logs additional information about the request and response. The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any). *message* is the log entry. *log_type* identifies the type of log entry. Possible values are as follows: - "Info" - "RequestHeaders" - "ResponseHeaders" - "RequestBody" - "ResponseBody" - "ProxyRequest" - "ProxyResponse" - "FirewallRequest" - "FirewallResponse" # on_pi_trail event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This event traces the commands sent to the mail server, and the respective replies. ## Syntax *Rust Syntax* ```text // PFileMailerPITrailEventArgs carries the PFileMailer PITrail event's parameters. pub struct PFileMailerPITrailEventArgs { fn direction(&self) -> i32 fn message(&self) -> &String } // PFileMailerPITrailEvent defines the signature of the PFileMailer PITrail event's handler function. pub trait PFileMailerPITrailEvent { fn on_pi_trail(&self, sender : PFileMailer, e : &mut PFileMailerPITrailEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_pi_trail(&self) -> &'a dyn PFileMailerPITrailEvent; pub fn set_on_pi_trail(&mut self, value : &'a dyn PFileMailerPITrailEvent); ... } ``` ## Remarks The on_pi_trail event is useful for debugging purposes. It shows all of the interaction between the client and the server, line by line, except for message header and body transfers. The *message* parameter contains the full text of the message. The *direction* parameter shows the originator of the message: | | | | --- | --- | | 0 (Client) | The message originates from the client. | | 1 (Server) | The message originates from the server. | | 2 (Info) | The message is an informative message originating from the client software (the struct code). | # on_progress event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Fired as progress is made. ## Syntax *Rust Syntax* ```text // PFileMailerProgressEventArgs carries the PFileMailer Progress event's parameters. pub struct PFileMailerProgressEventArgs { fn bytes_processed(&self) -> i64 fn percent_processed(&self) -> i32 } // PFileMailerProgressEvent defines the signature of the PFileMailer Progress event's handler function. pub trait PFileMailerProgressEvent { fn on_progress(&self, sender : PFileMailer, e : &mut PFileMailerProgressEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_progress(&self) -> &'a dyn PFileMailerProgressEvent; pub fn set_on_progress(&mut self, value : &'a dyn PFileMailerProgressEvent); ... } ``` ## Remarks This event is fired automatically as data is processed by the struct. The *PercentProcessed* parameter indicates the current status of the operation. The *BytesProcessed* parameter holds the total number of bytes processed so far. # on_ssl_server_authentication event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Fired after the server presents its certificate to the client. ## Syntax *Rust Syntax* ```text // PFileMailerSSLServerAuthenticationEventArgs carries the PFileMailer SSLServerAuthentication event's parameters. pub struct PFileMailerSSLServerAuthenticationEventArgs { fn cert_encoded(&self) -> &[u8] fn cert_subject(&self) -> &String fn cert_issuer(&self) -> &String fn status(&self) -> &String fn accept(&self) -> bool fn set_accept(&self, value : bool) } // PFileMailerSSLServerAuthenticationEvent defines the signature of the PFileMailer SSLServerAuthentication event's handler function. pub trait PFileMailerSSLServerAuthenticationEvent { fn on_ssl_server_authentication(&self, sender : PFileMailer, e : &mut PFileMailerSSLServerAuthenticationEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_ssl_server_authentication(&self) -> &'a dyn PFileMailerSSLServerAuthenticationEvent; pub fn set_on_ssl_server_authentication(&mut self, value : &'a dyn PFileMailerSSLServerAuthenticationEvent); ... } ``` ## Remarks During this event, the client can decide whether or not to continue with the connection process. The *accept* parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue. When *accept* is False, *status* shows why the verification failed (otherwise, *status* contains the string *OK*). If it is decided to continue, you can override and accept the certificate by setting the *accept* parameter to True. # on_ssl_status event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Fired when secure connection progress messages are available. ## Syntax *Rust Syntax* ```text // PFileMailerSSLStatusEventArgs carries the PFileMailer SSLStatus event's parameters. pub struct PFileMailerSSLStatusEventArgs { fn message(&self) -> &String } // PFileMailerSSLStatusEvent defines the signature of the PFileMailer SSLStatus event's handler function. pub trait PFileMailerSSLStatusEvent { fn on_ssl_status(&self, sender : PFileMailer, e : &mut PFileMailerSSLStatusEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_ssl_status(&self) -> &'a dyn PFileMailerSSLStatusEvent; pub fn set_on_ssl_status(&mut self, value : &'a dyn PFileMailerSSLStatusEvent); ... } ``` ## Remarks The event is fired for informational and logging purposes only. This event tracks the progress of the connection. # on_start_transfer event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This event is fired when the message text starts transferring. ## Syntax *Rust Syntax* ```text // PFileMailerStartTransferEventArgs carries the PFileMailer StartTransfer event's parameters. pub struct PFileMailerStartTransferEventArgs { fn direction(&self) -> i32 } // PFileMailerStartTransferEvent defines the signature of the PFileMailer StartTransfer event's handler function. pub trait PFileMailerStartTransferEvent { fn on_start_transfer(&self, sender : PFileMailer, e : &mut PFileMailerStartTransferEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_start_transfer(&self) -> &'a dyn PFileMailerStartTransferEvent; pub fn set_on_start_transfer(&mut self, value : &'a dyn PFileMailerStartTransferEvent); ... } ``` ## Remarks If [message_text](#message_text-property-pfilemailer-struct) is not empty, the on_start_transfer event is fired when the [message_text](#message_text-property-pfilemailer-struct) starts transferring from the local host to the [mail_server](#mail_server-property-pfilemailer-struct). If [message_text](#message_text-property-pfilemailer-struct) is empty, the event is not fired. If a file is attached to the [message_text](#message_text-property-pfilemailer-struct) via the attached_file property, then on_start_transfer fires again when the file starts transferring. Please go to the description of the attached_file property for more information. The *Direction* parameter shows whether the client (0) or the server (1) is sending the data. # on_status event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) Shows the progress of the operation. ## Syntax *Rust Syntax* ```text // PFileMailerStatusEventArgs carries the PFileMailer Status event's parameters. pub struct PFileMailerStatusEventArgs { fn message(&self) -> &String } // PFileMailerStatusEvent defines the signature of the PFileMailer Status event's handler function. pub trait PFileMailerStatusEvent { fn on_status(&self, sender : PFileMailer, e : &mut PFileMailerStatusEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_status(&self) -> &'a dyn PFileMailerStatusEvent; pub fn set_on_status(&mut self, value : &'a dyn PFileMailerStatusEvent); ... } ``` ## Remarks The event is fired for informational and logging purposes only. It may be used to track the progress of an operation. The level of detail is controlled by the [LogLevel](#LogLevel) setting. # on_transfer event ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) This event is fired when the message text is transferred to MailServer . ## Syntax *Rust Syntax* ```text // PFileMailerTransferEventArgs carries the PFileMailer Transfer event's parameters. pub struct PFileMailerTransferEventArgs { fn direction(&self) -> i32 fn bytes_transferred(&self) -> i64 fn percent_done(&self) -> i32 fn text(&self) -> &[u8] } // PFileMailerTransferEvent defines the signature of the PFileMailer Transfer event's handler function. pub trait PFileMailerTransferEvent { fn on_transfer(&self, sender : PFileMailer, e : &mut PFileMailerTransferEventArgs); } impl <'a> PFileMailer<'a> { pub fn on_transfer(&self) -> &'a dyn PFileMailerTransferEvent; pub fn set_on_transfer(&mut self, value : &'a dyn PFileMailerTransferEvent); ... } ``` ## Remarks One or more on_transfer events are fired during message delivery. Messages consist of [message_text](#message_text-property-pfilemailer-struct) and an optional attached_file. The *bytes_transferred* parameter shows the number of bytes sent starting from the beginning of [message_text](#message_text-property-pfilemailer-struct) or attached_file. *text* contains the current portion of the message being sent. The *Direction* parameter shows whether the client (0) or the server (1) is sending the data. The *PercentDone* parameter shows the progress of the transfer in the corresponding direction. If *PercentDone* can not be calculated the value will be -1. NOTE: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance. # Config Settings ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) The struct accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these *internal properties* is provided through the [config](#config-method-pfilemailer-struct) method. ### PFILEMailer Config Settings **ClearSignature**: Specifies whether or not to create a cleartext signature.This setting controls whether or not a cleartext signature is created during signing. The default value is True. When set to True a cleartext signature will be created when [sign](#sign-method-pfilemailer-struct) is called. Note: some mail applications such as GpgOL cannot process cleartext signatures. **Comment**: The OpenPGP message comment.OpenPGP messages may contain a comment. A comment may optionally be set before calling [encrypt](#encrypt-method-pfilemailer-struct), [sign](#sign-method-pfilemailer-struct), or [sign_and_encrypt](#sign_and_encrypt-method-pfilemailer-struct). **CompressionLevel**: The level of compression used.This setting specifies the level of compression used: possible values depend on the value of [compression_method](#compression_method-property-pfilemailer-struct) and are detailed below. This value is passed directly to the underlying compression library: | | | | --- | --- | | zlib | -1 (library default), or 0-9 | | zip | -1 (library default), or 0-9 | | bzip2 | 1-9 | For *zlib* and *zip*, -1 requests the library's own default compression level (typically equivalent to *6*). For *bzip2*, which has no native default level, a value of -1 is treated as *4*. Higher values (other than -1) cause the struct to compress better; lower values cause it to compress faster. The default value is -1. **EnsureValidDSASignatureHashAlgorithm**: Whether or not to select a suitable signature hash algorithm automatically.This setting specifies whether the struct ensures a valid hash algorithm is selected for use with the loaded DSA or ECDSA key. The default value is True. ## DSA Notes DSA requires that the hash be 160 bits or larger, which means MD5 is not a suitable algorithm. When DSA Signature Hash Algorithm selection is enabled (default) the struct will use the preferred algorithm from the key if it meets the requirements for DSA. If the preferred algorithm is MD5 and does not meed the requirements for DSA the struct will automatically use a suitable algorithm based on the Q element of the DSA key (may be SHA1, SHA224, or SHA256). ## ECDSA Notes The ECDSA Signature Hash Algorithm requirements are directly related to the [key_curve](#key_curve-property-pfilemailer-struct) used by the key. When this setting is enabled (default) the struct will use the preferred algorithm from the key if it meets the requirements for ECDSA. If the preferred algorithm does not meet the requirements the struct will automatically select a valid hash algorithm based on the curve as follows: | Curve | Hash Algorithm | | --- | --- | | secp256r1 | SHA256 | | secp384r1 | SHA384 | | secp521r1 | SHA512 | | secp256k1 | SHA256 | **LogLevel**: Specifies the level of detail that is logged.This setting controls the level of detail that is logged through the [on_status](#on_status-event-pfilemailer-struct) event. Possible values are: | | | | --- | --- | | 0 (None) | No events are logged. | | 1 (Info - default) | Informational events are logged. | | 2 (Verbose) | Detailed data is logged. | | 3 (Debug) | Debug data is logged. | **ProcessAttachments**: Whether or not to process attachments.This setting controls whether attachments are processed when calling [encrypt](#encrypt-method-pfilemailer-struct), [sign](#sign-method-pfilemailer-struct), or [sign_and_encrypt](#sign_and_encrypt-method-pfilemailer-struct). If set to True the attachments will also be encrypted and/or signed. If set to False the attachments will be added to the message with no additional processing. The default value is False. **SymmetricPassphrase**: The password used for symmetric encryption or decryption.This setting specifies the passphrase when using symmetric encryption. If a value is provided, symmetric encryption/decryption will be attempted. In this case no keys are used for either encryption or decryption. Only [encrypt](#encrypt-method-pfilemailer-struct) and decrypt are valid operations when a value is set. [sign](#sign-method-pfilemailer-struct), [sign_and_encrypt](#sign_and_encrypt-method-pfilemailer-struct), verify_signature, and decrypt_and_verify_signature are not valid operations when using this option. **VersionHeader**: The Version header value in the ASCII armored OpenPGP message.This setting specifies the Version header value included in the ASCII armored OpenPGP message. This may be set before calling [encrypt](#encrypt-method-pfilemailer-struct), [sign](#sign-method-pfilemailer-struct), or [sign_and_encrypt](#sign_and_encrypt-method-pfilemailer-struct). The default value is "IPWorks PGP 2026". This setting will be populated after calling decrypt, verify_signature, or decrypt_and_verify_signature. ### FileMailer Config Settings **AttachmentEncoding[index]**: Content-Transfer-Encoding for attached file (at index).This configuration setting allows you to set the Content-Transfer-Encoding for each attached file in the attachments array property. Valid array indices are from 0 to **AttachmentCount** -1. When set to one of the following integer values, the attachment will be encoded using the specified encoding. The following encodings are supported: | | | | --- | --- | | 0 | 7-bit | | 1 | Quoted-Printable | | 2 | Base64 | | 3 | 8-bit | **AttachmentText[index]**: Add the text into the attachment at the specified index.If this is set, text will be added into the attachment at the specified index. All data entered must be hex-encoded data. The struct will then decode the hex-encoded data and insert the data into the attachment. **AttachmentType[index]**: Content-type for attached file (at index).This configuration setting allows you to set the Content-Type for each attached file in the attachments array property. Valid array indices are from 0 to **AttachmentCount** -1. To set the Content-Type for the attachment at index 2, you would set the string "AttachmentType[2]=application/octet-stream". **Charset**: When set, the charset Content-Type attribute will be added using the specified value.This property is used to specify the "charset" Content-Type attribute for the plain text ([message_text](#message_text-property-pfilemailer-struct)) part header. The default value is "" (empty string), in which case the charset attribute will not be added to the Content-Type header. **MessageTextEncoding**: When set, the MessageText value will be encoded using the specified encoding.When set to one of the following integer values, the [message_text](#message_text-property-pfilemailer-struct) properties will be encoded using the specified encoding. The "Content-Transfer-Encoding" header also will be set for the plain text. The following encodings are supported: | | | | --- | --- | | 0 | 7-bit | | 1 | Quoted-Printable | | 2 | Base64 | | 3 | 8-bit | **OverrideFileName**: If set to true, the AttachmentName property value will be used to set the MIME part FileName attribute.When set to True, the [attachment_name](#attachment_name-property-pfilemailer-struct) value specified will be used to set the FileName attribute of the Content-Disposition header. The default value is False, in which case, the component will use the same name as the file being added. **TempFilePath**: If set, the temporary files created during message creation will be put in the path specified.The [TempFilePath](#TempFilePath) configuration sets the path at which the temporary files will be created. **UseTempFile**: If set, the struct uses temporary files when generating messages.This controls whether or not the struct will use a temporary file when creating messages to be sent. Set this to True if the outgoing message contains large images or attachments. **Note: Be aware of security considerations when using this configuration.** ### SMTP Config Settings **AllowEmptyTo**: If set to True, then the SendTo property is not required.Normally, the [send_to](#send_to-property-pfilemailer-struct) property is required to send a message. If [AllowEmptyTo](#AllowEmptyTo) is True, then this is not the case, and messages can be sent with just one or both of [cc](#cc-property-pfilemailer-struct) and [b_cc](#b_cc-property-pfilemailer-struct) set. **AuthorizationIdentity**: The value to use as the authorization identity when SASL authentication is used.When [auth_mechanism](#auth_mechanism-property-pfilemailer-struct) is set to amXOAUTH2, you may use this configuration setting to specify an authorization identity to be used when authenticating. In the case of amXOAUTH2, this should be your OAUTH authorization string. For instance: ```plaintext Bearer ya29.AHES6ZRmS-8xPbpGetC1VbABJIBRdKm-c4X7wMVGAbgxdGt5q8Ts3Q ``` NOTE: When using amXOAUTH2, [user](#user-property-pfilemailer-struct) must be specified, but [password](#password-property-pfilemailer-struct) is not required. **Charset**: When set, the message headers will be encoded using the specified Charset.This configuration setting is used to specify the "charset" to be used to encode the message headers. For example, to use UTF-8 you can set this property to "UTF-8". The default value is "" (empty string) in which case the headers will not be encoded. **Hello**: The argument for HELO (herald) command to the server (defaults to local host name).The [Hello](#Hello) property specifies a string to send to the [mail_server](#mail_server-property-pfilemailer-struct) at connection time as an argument to the SMTP *HELO* command. This generally identifies the host sending mail, and that is why the [Hello](#Hello) property defaults to the name of the local host. The property is provided in case the struct does not accept the default value and a custom value (e.g., a fully qualified domain name) must be sent. If allow_extensions is True, the *EHLO* command will be sent instead of the *HELO* command. **KeepQueue**: If set to True, queued files are not deleted after a successful send.Normally, [process_queue](#process_queue-method-pfilemailer-struct) deletes queued files after processing them. If [KeepQueue](#KeepQueue) is True, then the file extension is instead changed to ".sent" and the files are not deleted. **MaxHeaderLength**: Maximum length for headers to avoid line folding (default 80).The [MaxHeaderLength](#MaxHeaderLength) specifies the maximum line length supported by the mail delivery system. Any headers longer than [MaxHeaderLength](#MaxHeaderLength) are folded as specified in RFC 822. It is generally a good idea to use a [MaxHeaderLength](#MaxHeaderLength) of less than 100 bytes, although different mail relays and mail servers have different requirements for header lengths. **MessageHeadersString**: String representation of RFC822-encoded headers of the message.This setting holds the full headers of the message in RFC 822 format. Use this along with [TransferText](#TransferText) to store the entire message in RFC 822 format. **Example:** ```csharp smtp1.Send(); string rawMsg = smtp1.Config("MessageHeadersString") + smtp1.Config("TransferText"); ``` **MessageIdAlgorithm**: Determines the algorithm used to hash the random MessageId. The [MessageIdAlgorithm](#MessageIdAlgorithm) specifies which algorithm to use in the hash for the [message_id](#message_id-property-pfilemailer-struct) when the property is set to "*". The default value is "SHA1". Possible values are as follows: - "MD5" - "SHA1" (default) - "SHA256" **OtherHeaders**: An RFC 822 compliant string consisting of extra headers.This is the same as the [other_headers](#other_headers-property-pfilemailer-struct) property. This configuration setting is exposed for use by structs that are inherited from SMTP. **ReturnPath**: Sets the Return-Path to be used for sending email.This is the same as the return_path property. This configuration setting is exposed for use by structs that are inherited from SMTP. **SendRSET**: Whether to send RSET command.By default, the struct will periodically send the *RSET* command to the server. Changing this configuration setting to False will prevent the *RSET* command from being sent. This can be useful when interacting with some servers that do not respond properly to the *RSET* command. **StopOnBccErrors**: Instructs the struct to stop sending the message if the server does not acknowledge any of the BCCs.If this configuration setting is set to True, the struct will fail the moment the server does not acknowledge a Bcc address. If it is set to False, an error will be fired for every Bcc that is not recognized by the server, but the message will be sent to the rest of the recipients. The default value is False. **StopOnCcErrors**: Instructs the struct to stop sending the message if the server does not acknowledge any of the CCs.If this configuration setting is set to True, the struct will fail the moment the server does not acknowledge a Cc address. If it is set to False, an error will be fired for every Cc that is not recognized by the server, but the message will be sent to the rest of the recipients. The default value is True. **StopOnToErrors**: Instructs the struct to stop sending the message if the server does not acknowledge any of the TOs.If this configuration setting is set to True, the struct will fail the moment the server does not acknowledge a To address. If it is set to False, an error will be fired for every To that is not recognized by the server, but the message will be sent to the rest of the recipients. The default value is True. **TransferText**: String representation of RFC822-encoded body of the message.This configuration setting holds the full body of the message in RFC 822 format. Use this along with [MessageHeadersString](#MessageHeadersString) to store the entire message in RFC 822 format. **Example:** ```csharp smtp1.Send(); string rawMsg = smtp1.Config("MessageHeadersString") + smtp1.Config("TransferText"); ``` ### TCPClient Config Settings **ConnectionTimeout**: Sets a separate timeout value for establishing a connection.When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the struct will use [timeout](#timeout-property-pfilemailer-struct) for establishing a connection and transmitting/receiving data. **FirewallAutoDetect**: Tells the struct whether or not to automatically detect and use firewall system settings, if available.This configuration setting is provided for use by structs that do not directly expose Firewall properties. **FirewallHost**: Name or IP address of firewall (optional).If a [FirewallHost](#FirewallHost) is given, requested connections will be authenticated through the specified firewall when connecting. If the [FirewallHost](#FirewallHost) setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the [FirewallHost](#FirewallHost) setting is set to the corresponding address. If the search is not successful, an error is returned. NOTE: This setting is provided for use by structs that do not directly expose Firewall properties. **FirewallHTTPVersion**: The HTTP version to be used when connecting through a tunneling proxy.When [FirewallType](#FirewallType) is set to a tunneling proxy, this setting dictates which HTTP version is used when connecting. **FirewallPassword**: Password to be used if authentication is to be used when connecting through the firewall.If [FirewallHost](#FirewallHost) is specified, the [FirewallUser](#FirewallUser) and [FirewallPassword](#FirewallPassword) settings are used to connect and authenticate to the given firewall. If the authentication fails, the struct fails with an error. NOTE: This setting is provided for use by structs that do not directly expose Firewall properties. **FirewallPort**: The TCP port for the FirewallHost;.The [FirewallPort](#FirewallPort) is set automatically when [FirewallType](#FirewallType) is set to a valid value. NOTE: This configuration setting is provided for use by structs that do not directly expose Firewall properties. **FirewallType**: Determines the type of firewall to connect through.Possible values are as follows: | | | | --- | --- | | 0 | No firewall (default setting). | | 1 | Connect through a tunneling proxy. [FirewallPort](#FirewallPort) is set to 80. | | 2 | Connect through a SOCKS4 Proxy. [FirewallPort](#FirewallPort) is set to 1080. | | 3 | Connect through a SOCKS5 Proxy. [FirewallPort](#FirewallPort) is set to 1080. | | 10 | Connect through a SOCKS4A Proxy. [FirewallPort](#FirewallPort) is set to 1080. | NOTE: This setting is provided for use by structs that do not directly expose Firewall properties. **FirewallUser**: A user name if authentication is to be used connecting through a firewall.If the [FirewallHost](#FirewallHost) is specified, the [FirewallUser](#FirewallUser) and [FirewallPassword](#FirewallPassword) settings are used to connect and authenticate to the Firewall. If the authentication fails, the struct fails with an error. NOTE: This setting is provided for use by structs that do not directly expose Firewall properties. **KeepAliveInterval**: The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.When set, [TCPKeepAlive](#TCPKeepAlive) will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by [KeepAliveTime](#KeepAliveTime). If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second. NOTE: This value is not applicable in macOS. **KeepAliveTime**: The inactivity time in milliseconds before a TCP keep-alive packet is sent.When set, [TCPKeepAlive](#TCPKeepAlive) will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds. **Linger**: When set to True, connections are terminated gracefully.This property controls how a connection is closed. The default is True. In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if [LingerTime](#LingerTime) is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires. In the second scenario, if [LingerTime](#LingerTime) is a positive value, the system will attempt to send pending data until the specified [LingerTime](#LingerTime) is reached. If this attempt fails, then the system will reset the connection. The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the struct returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes). Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action. **LingerTime**: Time in seconds to have the connection linger. LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout. **LocalHost**: The name of the local host through which connections are initiated or accepted. The [local_host](#local_host-property-pfilemailer-struct) setting contains the name of the local host as obtained by the *gethostname()* system call, or if the user has assigned an IP address, the value of that address. In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the struct initiate connections (or accept in the case of server structs) only through that interface. If the struct is connected, the [local_host](#local_host-property-pfilemailer-struct) setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface). **LocalPort**: The port in the local host where the struct binds. This configuration setting must be set before a connection is attempted. It instructs the struct to bind to a specific port (or communication endpoint) in the local machine. Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by local_port after the connection is established. local_port cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error. This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems. **MaxLineLength**: The maximum amount of data to accumulate when no EOL is found.[MaxLineLength](#MaxLineLength) is the size of an internal buffer, which holds received data while waiting for an eol string. If an eol string is found in the input stream before [MaxLineLength](#MaxLineLength) bytes are received, the on_data_in event is fired with the *EOL* parameter set to True, and the buffer is reset. If no eol is found, and [MaxLineLength](#MaxLineLength) bytes are accumulated in the buffer, the on_data_in event is fired with the *EOL* parameter set to False, and the buffer is reset. The minimum value for [MaxLineLength](#MaxLineLength) is 256 bytes. The default value is 2048 bytes. **MaxTransferRate**: The transfer rate limit in bytes per second.This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit. **ProxyExceptionsList**: A semicolon separated list of hosts and IPs to bypass when using a proxy.This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance: *www.google.com;www.example.com* **TCPKeepAlive**: Determines whether or not the keep alive socket option is enabled.If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set [KeepAliveTime](#KeepAliveTime) and [KeepAliveInterval](#KeepAliveInterval) to configure the timing of the keep-alive packets. NOTE: This value is not applicable in Java. **TcpNoDelay**: Whether or not to delay when sending packets. When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm. By default, this configuration setting is set to False. **UseIPv6**: Whether to use IPv6.When set to *0* (default), the struct will use IPv4 exclusively. When set to *1*, the struct will use IPv6 exclusively. To instruct the struct to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to *2*. The default value is *0*. Possible values are as follows: | | | | --- | --- | | 0 | IPv4 only | | 1 | IPv6 only | | 2 | IPv6 with IPv4 fallback | **UseNTLMv2**: Whether to use NTLM V2.When authenticating with NTLM, this setting specifies whether NTLM V2 is used. By default this value is True and NTLM V2 will be used. Set this to False to use NTLM V1. ### SSL Config Settings **LogSSLPackets**: Controls whether SSL packets are logged when using the internal security API.When [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Internal*, this configuration setting controls whether Secure Sockets Layer (SSL) packets should be logged. By default, this configuration setting is *False*, as it is useful only for debugging purposes. When enabled, SSL packet logs are output using the [on_ssl_status](#on_ssl_status-event-pfilemailer-struct) event, which will fire each time an SSL packet is sent or received. Enabling this configuration setting has no effect if [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Platform*. **OpenSSLCADir**: The path to a directory containing CA certificates.This functionality is available only when the provider is OpenSSL. The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details. **OpenSSLCAFile**: Name of the file containing the list of CA's trusted by your application.This functionality is available only when the provider is OpenSSL. The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences: -----BEGIN CERTIFICATE----- ... (CA certificate in base64 encoding) ... -----END CERTIFICATE----- Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details. **OpenSSLCipherList**: A string that controls the ciphers to be used by SSL.This functionality is available only when the provider is OpenSSL. The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH". **OpenSSLPrngSeedData**: The data to seed the pseudo random number generator (PRNG).This functionality is available only when the provider is OpenSSL. By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG. **ReuseSSLSession**: Determines if the SSL session is reused. If set to True, the struct will reuse the context if and only if the following criteria are met: - The target host name is the same. - The system cache entry has not expired (default timeout is 10 hours). - The application process that calls the function is the same. - The logon session is the same. - The instance of the struct is the same. **SSLCACerts**: A newline separated list of CA certificates to be included when performing an SSL handshake.When [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Internal*, this configuration setting specifies one or more CA certificates to be included with the ssl_cert property. Some servers or clients require the entire chain, including CA certificates, to be presented when performing SSL authentication. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance: ```text -----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert ... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE----- ``` **SSLCheckCRL**: Whether to check the Certificate Revocation List for the server certificate.This configuration setting specifies whether the struct will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the struct will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The struct will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the struct fails with an error. When set to 0 (default), the CRL check will not be performed by the struct. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported. This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems. **SSLCheckOCSP**: Whether to use OCSP to check the status of the server certificate.This configuration setting specifies whether the struct will use OCSP to check the validity of the server certificate. If set to 1 or 2, the struct will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The struct will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation, the struct fails with an error. When set to 0 (default), the struct will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported. This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems. **SSLCipherStrength**: The minimum cipher strength used for bulk encryption. This minimum cipher strength is largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated. NOTE: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the [on_ssl_status](#on_ssl_status-event-pfilemailer-struct) event. Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application. When the provider is OpenSSL, [SSLCipherStrength](#SSLCipherStrength) is currently not supported. This functionality is instead made available through the [OpenSSLCipherList](#OpenSSLCipherList) configuration setting. **SSLClientCACerts**: A newline separated list of CA certificates to use during SSL client certificate validation.This configuration setting is only applicable to server components (e.g., TCPServer) see [SSLServerCACerts](#SSLServerCACerts) for client components (e.g., TCPClient). This setting can be used to optionally specify one or more CA certificates to be used when verifying the client certificate that is presented by the client during the SSL handshake when ssl_authenticate_clients is enabled. When verifying the client's certificate, the certificates trusted by the system will be used as part of the verification process. If the client's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the client's CA certificates are not already trusted on the system and cannot be installed to the trusted system store. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance: ```text -----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert ... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE----- ``` **SSLEnabledCipherSuites**: The cipher suite to be used in an SSL negotiation.This configuration setting enables the cipher suites to be used in SSL negotiation. By default, the enabled cipher suites will include all available ciphers ("*"). The special value "*" means that the struct will pick all of the supported cipher suites. If [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) is set to any other value, only the specified cipher suites will be considered. Multiple cipher suites are separated by semicolons. Example values when [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Platform* include the following: ```text obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); ``` Possible values when [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Platform* include the following: - CALG_3DES - CALG_3DES_112 - CALG_AES - CALG_AES_128 - CALG_AES_192 - CALG_AES_256 - CALG_AGREEDKEY_ANY - CALG_CYLINK_MEK - CALG_DES - CALG_DESX - CALG_DH_EPHEM - CALG_DH_SF - CALG_DSS_SIGN - CALG_ECDH - CALG_ECDH_EPHEM - CALG_ECDSA - CALG_ECMQV - CALG_HASH_REPLACE_OWF - CALG_HUGHES_MD5 - CALG_HMAC - CALG_KEA_KEYX - CALG_MAC - CALG_MD2 - CALG_MD4 - CALG_MD5 - CALG_NO_SIGN - CALG_OID_INFO_CNG_ONLY - CALG_OID_INFO_PARAMETERS - CALG_PCT1_MASTER - CALG_RC2 - CALG_RC4 - CALG_RC5 - CALG_RSA_KEYX - CALG_RSA_SIGN - CALG_SCHANNEL_ENC_KEY - CALG_SCHANNEL_MAC_KEY - CALG_SCHANNEL_MASTER_HASH - CALG_SEAL - CALG_SHA - CALG_SHA1 - CALG_SHA_256 - CALG_SHA_384 - CALG_SHA_512 - CALG_SKIPJACK - CALG_SSL2_MASTER - CALG_SSL3_MASTER - CALG_SSL3_SHAMD5 - CALG_TEK - CALG_TLS1_MASTER - CALG_TLS1PRF Example values when [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Internal*include the following: ```text obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=TLS_DHE_DSS_WITH_AES_128_CBC_SHA"); obj.config("SSLEnabledCipherSuites=TLS_DHE_DSS_WITH_AES_128_CBC_SHA;TLS_ECDH_RSA_WITH_AES_128_CBC_SHA"); ``` Possible values when [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Internal* include the following: - TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 - TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 - TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 - TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 - TLS_ECDH_ECDSA_WITH_AES_256_GCM_SHA384 - TLS_RSA_WITH_AES_256_GCM_SHA384 - TLS_RSA_WITH_AES_128_GCM_SHA256 - TLS_ECDH_ECDSA_WITH_AES_128_GCM_SHA256 - TLS_DHE_DSS_WITH_AES_256_GCM_SHA384 - TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 - TLS_ECDH_RSA_WITH_AES_256_GCM_SHA384 - TLS_ECDH_RSA_WITH_AES_128_GCM_SHA256 - TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 - TLS_DHE_DSS_WITH_AES_128_GCM_SHA256 - TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 - TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 - TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA384 - TLS_DHE_DSS_WITH_AES_256_CBC_SHA256 - TLS_RSA_WITH_AES_256_CBC_SHA256 - TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 - TLS_ECDH_RSA_WITH_AES_256_CBC_SHA384 - TLS_DHE_RSA_WITH_AES_256_CBC_SHA256 - TLS_DHE_RSA_WITH_AES_128_CBC_SHA256 - TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 - TLS_RSA_WITH_AES_128_CBC_SHA256 - TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA256 - TLS_ECDH_RSA_WITH_AES_128_CBC_SHA256 - TLS_DHE_DSS_WITH_AES_128_CBC_SHA256 - TLS_RSA_WITH_AES_256_CBC_SHA - TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA - TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA - TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA - TLS_DHE_RSA_WITH_AES_256_CBC_SHA - TLS_ECDH_RSA_WITH_AES_256_CBC_SHA - TLS_DHE_DSS_WITH_AES_256_CBC_SHA - TLS_RSA_WITH_AES_128_CBC_SHA - TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA - TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA - TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA - TLS_ECDH_RSA_WITH_AES_128_CBC_SHA - TLS_DHE_RSA_WITH_AES_128_CBC_SHA - TLS_DHE_DSS_WITH_AES_128_CBC_SHA - TLS_ECDHE_ECDSA_WITH_3DES_EDE_CBC_SHA - TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA - TLS_ECDH_ECDSA_WITH_3DES_EDE_CBC_SHA - TLS_ECDH_RSA_WITH_3DES_EDE_CBC_SHA - TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA - TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA - TLS_RSA_WITH_3DES_EDE_CBC_SHA - TLS_RSA_WITH_DES_CBC_SHA - TLS_DHE_RSA_WITH_DES_CBC_SHA - TLS_DHE_DSS_WITH_DES_CBC_SHA - TLS_RSA_WITH_RC4_128_MD5 - TLS_RSA_WITH_RC4_128_SHA When TLS 1.3 is negotiated (see [SSLEnabledProtocols](#SSLEnabledProtocols)), only the following cipher suites are supported: - TLS_AES_256_GCM_SHA384 - TLS_CHACHA20_POLY1305_SHA256 - TLS_AES_128_GCM_SHA256 [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) is used together with [SSLCipherStrength](#SSLCipherStrength). **SSLEnabledProtocols**: Used to enable/disable the supported security protocols.This configuration setting is used to enable or disable the supported security protocols. Not all supported protocols are enabled by default. The default value is *4032* for client components, and *3072* for server components. To specify a combination of enabled protocol versions set this config to the binary *OR* of one or more of the following values: | | | | --- | --- | | TLS1.3 | 12288 (Hex 3000) | | TLS1.2 | 3072 (Hex C00) (Default - Client and Server) | | TLS1.1 | 768 (Hex 300) (Default - Client) | | TLS1 | 192 (Hex C0) (Default - Client) | | SSL3 | 48 (Hex 30) | | SSL2 | 12 (Hex 0C) | Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases. **SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:** By default when TLS 1.3 is enabled, the struct will first try to use the platform TLS 1.3 implementation when the [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to Automatic for all editions. If the platform TLS 1.3 implementation is not available, the internal implementation will be used. In editions that are designed to run on Windows, [ssl_provider](#ssl_provider-property-pfilemailer-struct) can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version. If set to *1* (Platform provider), please be aware of the following notes: - The platform provider is available only on Windows 11/Windows Server 2022 and up. - [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) and other similar SSL configuration settings are not supported. - If [SSLEnabledProtocols](#SSLEnabledProtocols) includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions. **SSLEnabledProtocols: SSL2 and SSL3 Notes: ** SSL 2.0 and 3.0 are not supported by the struct when the [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and [ssl_provider](#ssl_provider-property-pfilemailer-struct) needs to be set to platform. **SSLEnableRenegotiation**: Whether the renegotiation_info SSL extension is supported.This configuration setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This configuration setting is *false* by default, but it can be set to *true* to enable the extension. This configuration setting is applicable only when [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Internal*. **SSLIncludeCertChain**: Whether the entire certificate chain is included in the SSLServerAuthentication event.This configuration setting specifies whether the Encoded parameter of the [on_ssl_server_authentication](#on_ssl_server_authentication-event-pfilemailer-struct) event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the [on_ssl_server_authentication](#on_ssl_server_authentication-event-pfilemailer-struct) event. If set to True, all certificates returned by the server will be present in the Encoded parameter of the [on_ssl_server_authentication](#on_ssl_server_authentication-event-pfilemailer-struct) event. This includes the leaf certificate, any intermediate certificate, and the root certificate. **SSLKeyLogFile**: The location of a file where per-session secrets are written for debugging purposes.This configuration setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes. When set, the struct will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the struct will only append, it will not overwrite previous values. NOTE: This configuration setting is applicable only when [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Internal*. **SSLNegotiatedCipher**: Returns the negotiated cipher suite.This configuration setting returns the cipher suite negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedCipher[connId]"); ``` **SSLNegotiatedCipherStrength**: Returns the negotiated cipher suite strength.This configuration setting returns the strength of the cipher suite negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedCipherStrength[connId]"); ``` **SSLNegotiatedCipherSuite**: Returns the negotiated cipher suite.This configuration setting returns the cipher suite negotiated during the SSL handshake represented as a single string. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedCipherSuite[connId]"); ``` **SSLNegotiatedKeyExchange**: Returns the negotiated key exchange algorithm.This configuration setting returns the key exchange algorithm negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedKeyExchange[connId]"); ``` **SSLNegotiatedKeyExchangeStrength**: Returns the negotiated key exchange algorithm strength.This configuration setting returns the strength of the key exchange algorithm negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedKeyExchangeStrength[connId]"); ``` **SSLNegotiatedVersion**: Returns the negotiated protocol version.This configuration setting returns the protocol version negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedVersion[connId]"); ``` **SSLSecurityFlags**: Flags that control certificate verification.The following flags are defined (specified in hexadecimal notation). They can be ORed together to exclude multiple conditions: | | | | --- | --- | | 0x00000001 | Ignore time validity status of certificate. | | 0x00000002 | Ignore time validity status of CTL. | | 0x00000004 | Ignore non-nested certificate times. | | 0x00000010 | Allow unknown certificate authority. | | 0x00000020 | Ignore wrong certificate usage. | | 0x00000100 | Ignore unknown certificate revocation status. | | 0x00000200 | Ignore unknown CTL signer revocation status. | | 0x00000400 | Ignore unknown certificate authority revocation status. | | 0x00000800 | Ignore unknown root revocation status. | | 0x00008000 | Allow test root certificate. | | 0x00004000 | Trust test root certificate. | | 0x80000000 | Ignore non-matching CN (certificate CN non-matching server name). | This functionality is currently not available when the provider is OpenSSL. **SSLServerCACerts**: A newline separated list of CA certificates to use during SSL server certificate validation.This configuration setting is only used by client components (e.g., TCPClient) see [SSLClientCACerts](#SSLClientCACerts) for server components (e.g., TCPServer). This configuration setting can be used to optionally specify one or more CA certificates to be used when connecting to the server and verifying the server certificate. When verifying the server's certificate, the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance: ```text -----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE----- ``` **TLS12SignatureAlgorithms**: Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.This configuration setting specifies the allowed server certificate signature algorithms when [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Internal* and [SSLEnabledProtocols](#SSLEnabledProtocols) is set to allow TLS 1.2. When specified the struct will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the struct fails with an error. The format of this value is a comma-separated list of hash-signature combinations. For instance: ```csharp component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); ``` The default value for this configuration setting is *sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa*. To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent. **TLS12SupportedGroups**: The supported groups for ECC.This configuration setting specifies a comma-separated list of named groups used in TLS 1.2 for ECC. The default value is *ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1*. When using TLS 1.2 and [ssl_provider](#ssl_provider-property-pfilemailer-struct) is set to *Internal*, the values refer to the supported groups for ECC. The following values are supported: - "ecdhe_secp256r1" (default) - "ecdhe_secp384r1" (default) - "ecdhe_secp521r1" (default) **TLS13KeyShareGroups**: The groups for which to pregenerate key shares.This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional roundtrip during the handshake if the group is supported by the server. The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting. NOTE: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group. In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so. The default value is *ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072* The values are ordered from most preferred to least preferred. The following values are supported: - "ecdhe_x25519" (default) - "ecdhe_x448" - "ecdhe_secp256r1" (default) - "ecdhe_secp384r1" (default) - "ecdhe_secp521r1" - "ffdhe_2048" (default) - "ffdhe_3072" (default) - "ffdhe_4096" - "ffdhe_6144" - "ffdhe_8192" **TLS13SignatureAlgorithms**: The allowed certificate signature algorithms.This configuration setting holds a comma-separated list of allowed signature algorithms. Possible values include the following: - "ed25519" (default) - "ed448" (default) - "ecdsa_secp256r1_sha256" (default) - "ecdsa_secp384r1_sha384" (default) - "ecdsa_secp521r1_sha512" (default) - "rsa_pkcs1_sha256" (default) - "rsa_pkcs1_sha384" (default) - "rsa_pkcs1_sha512" (default) - "rsa_pss_sha256" (default) - "rsa_pss_sha384" (default) - "rsa_pss_sha512" (default) The default value is *rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448*. This configuration setting is applicable only when [SSLEnabledProtocols](#SSLEnabledProtocols) includes TLS 1.3. **TLS13SupportedGroups**: The supported groups for (EC)DHE key exchange.This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. This configuration setting should be modified only if there is a specific reason to do so. The default value is *ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192,mlkem_512,mlkem_768,mlkem_1024,x25519_mlkem_768,secp256r1_mlkem_768* The values are ordered from most preferred to least preferred. The following values are supported: - "ecdhe_x25519" (default) - "ecdhe_x448" (default) - "ecdhe_secp256r1" (default) - "ecdhe_secp384r1" (default) - "ecdhe_secp521r1" (default) - "ffdhe_2048" (default) - "ffdhe_3072" (default) - "ffdhe_4096" (default) - "ffdhe_6144" (default) - "ffdhe_8192" (default) - "mlkem_512" (default) - "mlkem_768" (default) - "mlkem_1024" (default) - "x25519_mlkem_768" (default) - "secp256r1_mlkem_768" (default) Post-quantum algorithms (*mlkem_512,mlkem_768,mlkem_1024,x25519_mlkem_768,secp256r1_mlkem_768*) in our components rely on the operating system's underlying cryptographic primitives. The following platforms are currently supported: - Windows Server 2025 - Windows 11 24H2 - Windows 11 25H2 ### Socket Config Settings **AbsoluteTimeout**: Determines whether timeouts are inactivity timeouts or absolute timeouts.If [AbsoluteTimeout](#AbsoluteTimeout) is set to True, any method that does not complete within [timeout](#timeout-property-pfilemailer-struct) seconds will be aborted. By default, *AbsoluteTimeout* is False, and the timeout is an inactivity timeout. NOTE: This option is not valid for User Datagram Protocol (UDP) ports. **FirewallData**: Used to send extra data to the firewall.When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes). **InBufferSize**: The size in bytes of the incoming queue of the socket.This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the *InBufferSize* setting can provide significant improvements in performance. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the struct is activated the *InBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small. **OutBufferSize**: The size in bytes of the outgoing queue of the socket.This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the *OutBufferSize* setting can provide significant improvements in performance. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the struct is activated the *OutBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small. ### Base Config Settings **BuildInfo**: Information about the product's build.When queried, this setting will return a string containing information about the product's build. **CodePage**: The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001).

It will return the following information: - Product: The product the license is for. - Product Key: The key the license was generated from. - License Source: Where the license was found (e.g., RuntimeLicense, License File). - License Type: The type of license installed (e.g., Royalty Free, Single Server). - Last Valid Build: The last valid build number for which the license will work. **MaskSensitiveData**: Whether sensitive data is masked in log messages.In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to *true* to mask sensitive data. The default is *true*. **UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the struct will use the system security libraries by default to perform cryptographic functions where applicable. Setting this configuration setting to *true* tells the struct to use the internal implementation instead of using the system security libraries. On Windows, this setting is set to *false* by default. On Linux/macOS, this setting is set to *true* by default. To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the [OpenSSL Notes](platforms.md) section. # Trappable Errors ([PFileMailer](#struct-ipworkspgppfilemailer) Struct) ### FileMailer Errors | | | | --- | --- | | 169 | Invalid attachment index (out of range). | | 170 | Cannot create temporary file. | The class may also return one of the following error codes, which are inherited from other classes. ### MIME Errors | | | | --- | --- | | 3 | Can't create the file for write (illegal name or disk is write-protected). | | 4 | Can't open the file for read (doesn't exist?). | | 5 | Can't read from file. | | 6 | Can't write to file (disk full?). | | 280 | Invalid Part Index. | | 281 | Unknown MIME type. | | 282 | No MIME-boundary found. | | 283 | No file given. | | 284 | The struct is busy. | | 285 | Can't create a temporary file to decode the data. | | 286 | Can't read message file. | | 287 | No header separator found. | | 289 | No separator found. | | 290 | Input stream must have seeking enabled. | ### SMTP Errors | | | | --- | --- | | 118 | Firewall Error.
