# AS1Sender Component The AS1Sender class implements an AS1 / EDI-INT client, capable of sending EDI messages over electronic mail. ## Syntax ```text ipworksedi.AS1Sender ``` ## Remarks The AS1Sender component is used to send EDI or other messages over SMTP/S, using the AS1 protocol specified in RFC 3335. The struct is also used to retrieve and verify server responses. A typical AS1 transaction is as follows: (1) The sender sends an EDI document to the receiver using SMTP or SMTPS. Typically the document will be signed and encrypted (particularly if TLS/SSL is not used). A signed receipt will also be requested. (2) The receiver decrypts the message and verifies the signature. (3) The receiver sends a signed receipt back to the client. The signature is over the hash of an MDN, which contains a hash of the received message. **When sending an EDI message**, the client should specify, at a minimum, [From](#from-property-as1sender-component) and [SendTo](#sendto-property-as1sender-component), [MailServer](#mailserver-property-as1sender-component), and [EDIData](#edidata-property-as1sender-component) and [EDIType](#editype-property-as1sender-component). The [Send](#send-method-as1sender-component) method should then be invoked. **To secure the EDI transmission**, the message may be signed and/or encrypted by setting the appropriate certificates. By default, the struct will apply message security if the appropriate certificates are specified. To sign the data set SigningCert. To encrypt, set RecipientCerts. **TLS/SSL** will also be used if [SSLStartMode](#sslstartmode-property-as1sender-component) is set. In case your trading partner is using a self-signed certificate with their mail server it will be necessary to set SSLAcceptServerCert or trap the [SSLServerAuthentication](#sslserverauthentication-event-as1sender-component) event to accept the certificate. The message may also be **compressed** by setting [CompressionFormat](#compressionformat-property-as1sender-component). **To request a receipt**, or Message Disposition Notification (MDN), simply set the [MDNTo](#mdnto-property-as1sender-component) property. The MDN will be returned in a separate email response. The [MDNOptions](#mdnoptions-property-as1sender-component) property may be used to customize the request. By default, the struct will request a signed MDN over an SHA1 hash. **Validating AS1 MDNs** AS1 MDNs are returned asynchronously in a separate email. Generally MDNs will not be returned immediately. The struct supports the use of the POP/S protocol for receiving e-mail. To receive an MDN, set the [MailServer](#mailserver-property-as1sender-component), [User](#user-property-as1sender-component), and [Password](#password-property-as1sender-component) properties, and call [Connect](#connect-method-as1sender-component). At this point you may search your mailbox using the **MailMessage** properties; when you have found the appropriate message you should invoke [ReadReceipt](#readreceipt-method-as1sender-component), which will set MDNReceipt. If the receipt is indeed an MDN it will also be parsed (although not verified) and [MessageId](#messageid-property-as1sender-component) will be set. If the message is not an MDN an exception will be thrown. You should then use the values of [From](#from-property-as1sender-component) and [MessageId](#messageid-property-as1sender-component) to look up your trading partner's certificates, the [MDNOptions](#mdnoptions-property-as1sender-component) requested, and the [OriginalContentMIC](#originalcontentmic-property-as1sender-component) calculated when you sent the original message (you *must* store this value externally to verify signed receipts). Finally, invoke [VerifyReceipt](#verifyreceipt-method-as1sender-component). ## Property List *The following is the full list of the properties of the component with short descriptions.

The recipient is given by [SendTo](#sendto-property-as1sender-component). Note that From and [SendTo](#sendto-property-as1sender-component) correspond to the sender and recipient of the original message. For MDNs the roles are reversed, so that From indicates the *recipient*, and [SendTo](#sendto-property-as1sender-component) indicates the *sender* of the MDN. ## Data Type **string** # LocalHost Property ([AS1Sender](#as1sender-component) Component) The name of the local host or user-assigned IP interface through which connections are initiated or accepted. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) LocalHost() (string, error)func (obj *AS1Sender) SetLocalHost(value string) error ``` ## 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 LocalHost 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: LocalHost is not persistent. You must always set it in code, and never in the property window. ## Data Type **string** # LogDirectory Property ([AS1Sender](#as1sender-component) Component) The path to a directory for logging. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) LogDirectory() (string, error)func (obj *AS1Sender) SetLogDirectory(value string) error ``` ## Default Value "" ## Remarks Setting **LogDirectory** will instruct the component to log the details of each transmission to unique files in the specified directory. For each request processed, the struct will log the original EDI data, the complete text of the outgoing request and the incoming response. The struct will write a file for each transmission, with extension ".log". In case of error an additional file will be written with extension ".err", and the error will be reported in both files. Raw AS1 messages created or downloaded by the struct will be written with extension ".as1", and MDNs created or downloaded will be written with extension ".as1-mdn". The filenames will be chosen automatically by the struct. Each filename will be the system time, in the format YYYY-MM-DD-HH-MM-SS-MMMM, with extensions "-2", "-3", used in case files of those names already exist. After each transaction is processed [LogFile](#logfile-property-as1sender-component) will contain the name of the files just written, minus the extension ".log" or ".err". If logs cannot be written an exception will be thrown. ## Data Type **string** # LogFile Property ([AS1Sender](#as1sender-component) Component) The log file written. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) LogFile() (string, error) ``` ## Default Value "" ## Remarks In case [LogDirectory](#logdirectory-property-as1sender-component) is specified two log files will be written in the specified directory and LogFile will contain the path. LogFile will in fact refer to several files with appropriate extensions. A diagnostic log will be written with filename LogFile + ".log", and any EDI data read will be written with filename LogFile + ".dat". Raw AS1 messages and MDNs will also be written with extensions ".as1" and ".as1-mdn". This property is read-only. ## Data Type **string** # MailMessageCc Property ([AS1Sender](#as1sender-component) Component) The value of the Cc header of the mail message. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) MailMessageCc() (string, error) ``` ## Default Value "" ## Remarks After calling [SelectMailMessage](#selectmailmessage-method-as1sender-component) this property will be populated with the value of the Cc header of the mail message.

It is used to set and retrieve [configuration settings](#config-settings-as1sender-component) 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-as1sender-component), you must call *Config("PROPERTY")*. The value will be returned as a string. # Connect Method ([AS1Sender](#as1sender-component) Component) Connects to the incoming mail server. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) Connect() error ``` ## Remarks Connects to the incoming mail server specified by [MailServer](#mailserver-property-as1sender-component). You must set [User](#user-property-as1sender-component) and [Password](#password-property-as1sender-component) prior to calling Connect. The connection will be maintained until you call [Disconnect](#disconnect-method-as1sender-component). If you wish to connect in SSL you should first set the [SSLStartMode](#sslstartmode-property-as1sender-component) property. Note that it is not necessary to explicitly connect to an SMTP server for outgoing mail; a connection will be created and destroyed each time a mail is sent. # DeleteMessage Method ([AS1Sender](#as1sender-component) Component) Deletes the message specified by MailMessageNumber . ## Syntax *Go Syntax* ```text func (obj *AS1Sender) DeleteMessage() error ``` ## Remarks Requests that the [MailServer](#mailserver-property-as1sender-component) delete the message specified by [MailMessageNumber](#mailmessagenumber-property-as1sender-component).

It will be signed if SigningCert is set, encrypted if RecipientCert is set, and compressed if [CompressionFormat](#compressionformat-property-as1sender-component) is set. A receipt will be requested if [MDNTo](#mdnto-property-as1sender-component) is set. The queued message can then be sent by invoking [ProcessQueue](#processqueue-method-as1sender-component). # ReadReceipt Method ([AS1Sender](#as1sender-component) Component) Reads and parses (but does not verify) an MDN receipt. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) ReadReceipt() error ``` ## Remarks ReadReceipt will retrieve the file specified by [MailMessageNumber](#mailmessagenumber-property-as1sender-component) from the mail server, store it in MDNReceipt and attempt to parse it as an MDN receipt. If the file is a valid MDN receipt, the struct will determine the originator of the receipt and the [MessageId](#messageid-property-as1sender-component) of the original message. The originator of the receipt (your trading partner) will be stored in [SendTo](#sendto-property-as1sender-component), the intended recipient (presumably your system) will be stored in [From](#from-property-as1sender-component), and the original message Id will be stored in [MessageId](#messageid-property-as1sender-component). If you are not currently connected to a mail server, the struct will process the receipt specified by MDNReceipt. You should then look up the original message and set [OriginalContentMIC](#originalcontentmic-property-as1sender-component) to the value of [OriginalContentMIC](#originalcontentmic-property-as1sender-component) originally computed when the message was sent (you will need to save this information externally). You should also set ReceiptSignerCert based on the value of [SendTo](#sendto-property-as1sender-component) if necessary. Also, set [MDNOptions](#mdnoptions-property-as1sender-component) to the value used when making the original request. Finally, [VerifyReceipt](#verifyreceipt-method-as1sender-component) should be used to verify the receipt. # Reset Method ([AS1Sender](#as1sender-component) Component) Resets the state of the control. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) Reset() error ``` ## Remarks **Reset** resets the state of the struct. All properties will be set to their default values. # SelectMailMessage Method ([AS1Sender](#as1sender-component) Component) Selects and obtains information about the specified message. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) SelectMailMessage() error ``` ## Remarks This method selects the message specified by [MailMessageNumber](#mailmessagenumber-property-as1sender-component) and retrieves information about it. After calling this method properties such as [MailMessageHeaders](#mailmessageheaders-property-as1sender-component), [MailMessageDate](#mailmessagedate-property-as1sender-component), [MailMessageFrom](#mailmessagefrom-property-as1sender-component), etc. will be populated and allow you to determine if this message is an AS1 message. Additional properties are exposed via the [Config](#config-method-as1sender-component) method. If this message is an AS1 receipt (MDN), use [ReadReceipt](#readreceipt-method-as1sender-component) to read it. The MDNReceipt will then be populated with the receipt, and [SendTo](#sendto-property-as1sender-component) will be populated with the email address of the *originator*. ([From](#from-property-as1sender-component) and [SendTo](#sendto-property-as1sender-component) correspond to the originator and recipient of the original AS1 transmission.) You may then set trading partner information and invoke [VerifyReceipt](#verifyreceipt-method-as1sender-component) to verify the receipt. # Send Method ([AS1Sender](#as1sender-component) Component) Prepares and sends the AS1 message. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) Send() error ``` ## Remarks Invoking Send will prepare and send the AS1 message. It will be signed if SigningCert is set, encrypted if RecipientCert is set, and compressed if [CompressionFormat](#compressionformat-property-as1sender-component) is set. A receipt will be requested if [MDNTo](#mdnto-property-as1sender-component) is set. You should set [MailServer](#mailserver-property-as1sender-component) prior to sending. # SetRequestHeader Method ([AS1Sender](#as1sender-component) Component) Allows the user to set or add arbitrary HTTP request headers. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) SetRequestHeader(HeaderName string, HeaderValue string) error ``` ## Remarks *HeaderName* should contain the header name, and *HeaderValue* should contain its value. Use this to set headers such as *To*, *Date*, etc. Note that a default value for *Date* will automatically be determined and this method may be used to override the default. **SetRequestHeader** may be used to set any header except for the following: *AS2-To*, *AS2-From*, *AS2-Version*, *Subject*, *Message-Id*, *Disposition-Notification-To*, *Disposition-Notification-Options*, *Receipt-Delivery-Option*, *Host*, *Content-Length*. # VerifyReceipt Method ([AS1Sender](#as1sender-component) Component) Verifies an MDN receipt. ## Syntax *Go Syntax* ```text func (obj *AS1Sender) VerifyReceipt() error ``` ## Remarks **VerifyReceipt** verifies the receipt in MDNReceipt against the values of [OriginalContentMIC](#originalcontentmic-property-as1sender-component) and [MessageId](#messageid-property-as1sender-component) and the preferences specified in [MDNOptions](#mdnoptions-property-as1sender-component). The method operates similarly to Post: After the method finishes, the MDNReceipt, [ReceiptSigningProtocol](#ReceiptSigningProtocol), and ReceiptSignerCert properties will be populated with the appropriate values. The method operates synchronously, and will throw an exception if any errors or warnings occur. Errors might include a failure to decrypt or authenticate the receipt, the absence of an MDN when one was requested, TCP/IP errors, or any errors reported by the server in the MDN. Warnings might include the return of an unsigned receipt when a signed receipt was requested, or other warnings reported by the server in the MDN. If an exception is thrown the error code will correspond to the severity of the warning or error, allowing client software to determine whether or not to accept the reply. If multiple errors occur, the exception will return a special error code, and the error message will contain a line for each error's code and description; i.e. "423: Failed to authenticate sender". If the error(s) is/are not fatal processing will not be interrupted, and the relevant properties will be populated as normal. You should first invoke [ReadReceipt](#readreceipt-method-as1sender-component) when it is not known which message the receipt is in response to. This will allow you to determine the original [MessageId](#messageid-property-as1sender-component) and originator of the receipt before trying to verify it. # ConnectionStatus Event ([AS1Sender](#as1sender-component) Component) Fired to indicate changes in the connection state. ## Syntax *Go Syntax* ```text // AS1SenderConnectionStatusEventArgs carries the AS1Sender ConnectionStatus event's parameters. type AS1SenderConnectionStatusEventArgs struct {...} func (args *AS1SenderConnectionStatusEventArgs) ConnectionEvent() string func (args *AS1SenderConnectionStatusEventArgs) StatusCode() int32 func (args *AS1SenderConnectionStatusEventArgs) Description() string // AS1SenderConnectionStatusEvent defines the signature of the AS1Sender ConnectionStatus event's handler function. type AS1SenderConnectionStatusEvent func(sender *AS1Sender, args *AS1SenderConnectionStatusEventArgs) func (obj *AS1Sender) GetOnConnectionStatusHandler() AS1SenderConnectionStatusEvent func (obj *AS1Sender) SetOnConnectionStatusHandler(handlerFunc AS1SenderConnectionStatusEvent) ``` ## 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 *ConnectionEvent* 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. | *StatusCode* has the error code returned by the Transmission Control Protocol (TCP)/IP stack. *Description* contains a description of this code. The value of *StatusCode* is equal to the value of the error. # EndTransfer Event ([AS1Sender](#as1sender-component) Component) Fired when the message text completes transferring. ## Syntax *Go Syntax* ```text // AS1SenderEndTransferEventArgs carries the AS1Sender EndTransfer event's parameters. type AS1SenderEndTransferEventArgs struct {...} // AS1SenderEndTransferEvent defines the signature of the AS1Sender EndTransfer event's handler function. type AS1SenderEndTransferEvent func(sender *AS1Sender, args *AS1SenderEndTransferEventArgs) func (obj *AS1Sender) GetOnEndTransferHandler() AS1SenderEndTransferEvent func (obj *AS1Sender) SetOnEndTransferHandler(handlerFunc AS1SenderEndTransferEvent) ``` ## Remarks Fired when the message text completes transferring (on either a send or receive). # Error Event ([AS1Sender](#as1sender-component) Component) Fired when information is available about errors during data delivery. ## Syntax *Go Syntax* ```text // AS1SenderErrorEventArgs carries the AS1Sender Error event's parameters. type AS1SenderErrorEventArgs struct {...} func (args *AS1SenderErrorEventArgs) ErrorCode() int32 func (args *AS1SenderErrorEventArgs) Description() string // AS1SenderErrorEvent defines the signature of the AS1Sender Error event's handler function. type AS1SenderErrorEvent func(sender *AS1Sender, args *AS1SenderErrorEventArgs) func (obj *AS1Sender) GetOnErrorHandler() AS1SenderErrorEvent func (obj *AS1Sender) SetOnErrorHandler(handlerFunc AS1SenderErrorEvent) ``` ## Remarks The Error event is fired in case of exceptional conditions during message processing. Normally the struct fails with an error. The *ErrorCode* 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-as1sender-component) section. # Header Event ([AS1Sender](#as1sender-component) Component) This event is fired for every message header being retrieved. ## Syntax *Go Syntax* ```text // AS1SenderHeaderEventArgs carries the AS1Sender Header event's parameters. type AS1SenderHeaderEventArgs struct {...} func (args *AS1SenderHeaderEventArgs) Field() string func (args *AS1SenderHeaderEventArgs) Value() string // AS1SenderHeaderEvent defines the signature of the AS1Sender Header event's handler function. type AS1SenderHeaderEvent func(sender *AS1Sender, args *AS1SenderHeaderEventArgs) func (obj *AS1Sender) GetOnHeaderHandler() AS1SenderHeaderEvent func (obj *AS1Sender) SetOnHeaderHandler(handlerFunc AS1SenderHeaderEvent) ``` ## Remarks The *Field* parameter contains the name of the header (in the same case as it is delivered). The *Value* parameter contains the header contents. If the header line being retrieved is a continuation header line, then the *Field* parameter contains "" (empty string). # LaunchBrowser Event ([AS1Sender](#as1sender-component) Component) Fires before launching a browser with the authorization URL. ## Syntax *Go Syntax* ```text // AS1SenderLaunchBrowserEventArgs carries the AS1Sender LaunchBrowser event's parameters. type AS1SenderLaunchBrowserEventArgs struct {...} func (args *AS1SenderLaunchBrowserEventArgs) URL() string func (args *AS1SenderLaunchBrowserEventArgs) SetURL(value string) func (args *AS1SenderLaunchBrowserEventArgs) Command() string func (args *AS1SenderLaunchBrowserEventArgs) SetCommand(value string) // AS1SenderLaunchBrowserEvent defines the signature of the AS1Sender LaunchBrowser event's handler function. type AS1SenderLaunchBrowserEvent func(sender *AS1Sender, args *AS1SenderLaunchBrowserEventArgs) func (obj *AS1Sender) GetOnLaunchBrowserHandler() AS1SenderLaunchBrowserEvent func (obj *AS1Sender) SetOnLaunchBrowserHandler(handlerFunc AS1SenderLaunchBrowserEvent) ``` ## Remarks When the ClientProfile property is set to ocpApplication and GetAuthorization 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 # Log Event ([AS1Sender](#as1sender-component) Component) Fired with log information while processing a message. ## Syntax *Go Syntax* ```text // AS1SenderLogEventArgs carries the AS1Sender Log event's parameters. type AS1SenderLogEventArgs struct {...} func (args *AS1SenderLogEventArgs) LogType() string func (args *AS1SenderLogEventArgs) LogMessage() []byte // AS1SenderLogEvent defines the signature of the AS1Sender Log event's handler function. type AS1SenderLogEvent func(sender *AS1Sender, args *AS1SenderLogEventArgs) func (obj *AS1Sender) GetOnLogHandler() AS1SenderLogEvent func (obj *AS1Sender) SetOnLogHandler(handlerFunc AS1SenderLogEvent) ``` ## Remarks This event fires once for each log message generated by the struct. The verbosity is controlled by the [LogLevel](#LogLevel) setting. Log messages available through this event correspond to log files written to [LogDirectory](#logdirectory-property-as1sender-component). This event provides a way to obtain log messages without relying on files on disk. This event fires regardless of the value of [LogDirectory](#logdirectory-property-as1sender-component) (i.e. when [LogDirectory](#logdirectory-property-as1sender-component) is empty the event will still fire). The *LogMessage* event parameter holds the raw log data. The *LogType* event parameter indicates the type of log. Possible values are: | | | | --- | --- | | "LOG" | Information about the status of the process. | | "ERR" | An error was encountered. | | "DAT" | The EDI payload. | | "REQ" | The raw request | | "MDN" | The MDN response. | | "DEBUG" | Debug information. | | "DAT.INPUT" | Debug information when processing payload. Only applicable when [LogDebug](#LogDebug) is True. | | "DAT.ENCRYPT" | Debug information when processing payload. Only applicable when [LogDebug](#LogDebug) is True. | | "DAT.COMPRESS" | Debug information when processing payload. Only applicable when [LogDebug](#LogDebug) is True. | | "DAT.SIGN" | Debug information when processing payload. Only applicable when [LogDebug](#LogDebug) is True. | | "DAT.DECRYPT" | Debug information when processing payload. Only applicable when [LogDebug](#LogDebug) is True. | | "DAT.DECOMPRESS" | Debug information when processing payload. Only applicable when [LogDebug](#LogDebug) is True. | | "DAT.VERIFY" | Debug information when processing payload. Only applicable when [LogDebug](#LogDebug) is True. | | "DAT.DEBUG" | Debug information when processing payload. Only applicable when [LogDebug](#LogDebug) is True. | # PITrail Event ([AS1Sender](#as1sender-component) Component) This event traces the commands sent to the mail server, and the respective replies. ## Syntax *Go Syntax* ```text // AS1SenderPITrailEventArgs carries the AS1Sender PITrail event's parameters. type AS1SenderPITrailEventArgs struct {...} func (args *AS1SenderPITrailEventArgs) Direction() int32 func (args *AS1SenderPITrailEventArgs) Message() string // AS1SenderPITrailEvent defines the signature of the AS1Sender PITrail event's handler function. type AS1SenderPITrailEvent func(sender *AS1Sender, args *AS1SenderPITrailEventArgs) func (obj *AS1Sender) GetOnPITrailHandler() AS1SenderPITrailEvent func (obj *AS1Sender) SetOnPITrailHandler(handlerFunc AS1SenderPITrailEvent) ``` ## Remarks The PITrail 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). | # SSLServerAuthentication Event ([AS1Sender](#as1sender-component) Component) Fired after the server presents its certificate to the client. ## Syntax *Go Syntax* ```text // AS1SenderSSLServerAuthenticationEventArgs carries the AS1Sender SSLServerAuthentication event's parameters. type AS1SenderSSLServerAuthenticationEventArgs struct {...} func (args *AS1SenderSSLServerAuthenticationEventArgs) CertEncoded() []byte func (args *AS1SenderSSLServerAuthenticationEventArgs) CertSubject() string func (args *AS1SenderSSLServerAuthenticationEventArgs) CertIssuer() string func (args *AS1SenderSSLServerAuthenticationEventArgs) Status() string func (args *AS1SenderSSLServerAuthenticationEventArgs) Accept() bool func (args *AS1SenderSSLServerAuthenticationEventArgs) SetAccept(value bool) // AS1SenderSSLServerAuthenticationEvent defines the signature of the AS1Sender SSLServerAuthentication event's handler function. type AS1SenderSSLServerAuthenticationEvent func(sender *AS1Sender, args *AS1SenderSSLServerAuthenticationEventArgs) func (obj *AS1Sender) GetOnSSLServerAuthenticationHandler() AS1SenderSSLServerAuthenticationEvent func (obj *AS1Sender) SetOnSSLServerAuthenticationHandler(handlerFunc AS1SenderSSLServerAuthenticationEvent) ``` ## 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. # SSLStatus Event ([AS1Sender](#as1sender-component) Component) Fired when secure connection progress messages are available. ## Syntax *Go Syntax* ```text // AS1SenderSSLStatusEventArgs carries the AS1Sender SSLStatus event's parameters. type AS1SenderSSLStatusEventArgs struct {...} func (args *AS1SenderSSLStatusEventArgs) Message() string // AS1SenderSSLStatusEvent defines the signature of the AS1Sender SSLStatus event's handler function. type AS1SenderSSLStatusEvent func(sender *AS1Sender, args *AS1SenderSSLStatusEventArgs) func (obj *AS1Sender) GetOnSSLStatusHandler() AS1SenderSSLStatusEvent func (obj *AS1Sender) SetOnSSLStatusHandler(handlerFunc AS1SenderSSLStatusEvent) ``` ## Remarks The event is fired for informational and logging purposes only. This event tracks the progress of the connection. # StartTransfer Event ([AS1Sender](#as1sender-component) Component) Fired when the message text starts transferring (on either a send or receive). ## Syntax *Go Syntax* ```text // AS1SenderStartTransferEventArgs carries the AS1Sender StartTransfer event's parameters. type AS1SenderStartTransferEventArgs struct {...} // AS1SenderStartTransferEvent defines the signature of the AS1Sender StartTransfer event's handler function. type AS1SenderStartTransferEvent func(sender *AS1Sender, args *AS1SenderStartTransferEventArgs) func (obj *AS1Sender) GetOnStartTransferHandler() AS1SenderStartTransferEvent func (obj *AS1Sender) SetOnStartTransferHandler(handlerFunc AS1SenderStartTransferEvent) ``` ## Remarks Fired when the message text starts transferring (on either a send or receive). # Transfer Event ([AS1Sender](#as1sender-component) Component) Fired while the message text gets transferred to or from MailServer . ## Syntax *Go Syntax* ```text // AS1SenderTransferEventArgs carries the AS1Sender Transfer event's parameters. type AS1SenderTransferEventArgs struct {...} func (args *AS1SenderTransferEventArgs) BytesTransferred() int64 // AS1SenderTransferEvent defines the signature of the AS1Sender Transfer event's handler function. type AS1SenderTransferEvent func(sender *AS1Sender, args *AS1SenderTransferEventArgs) func (obj *AS1Sender) GetOnTransferHandler() AS1SenderTransferEvent func (obj *AS1Sender) SetOnTransferHandler(handlerFunc AS1SenderTransferEvent) ``` ## Remarks Fired while the message text gets transferred to or from [MailServer](#mailserver-property-as1sender-component). # Config Settings ([AS1Sender](#as1sender-component) Component) 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-as1sender-component) method. ### AS1 Config Settings **LogFilename**: The base name of the log file.If set, this will be used as for the filename of the log file. Note that only the base name should be specified as the component will append the appropriate file extension. **POPPort**: The POP mail port to be used, if different than MailServer.The mail port to be used for POP (or POP/S). For implicit SSL, use port 995. **POPServer**: The POP server to be used, if different than MailServer.The mail server to be used for POP (or POP/S), in case different than **MailServer**. **SMTPAuthMechanism**: The authentication mechanism used to connect to the SMTP server.By default, **SMTPAuthMechanism** is set to 0, which sends the AUTH command is **SMTPUser** and **SMTPPassword** are set. **SMTPAuthMechanism** can be set to 1 to use the more secure CRAM-MD5 authentication command. **SMTPPassword**: The password used for authentication.If SMTPPassword is set to a non empty string, then when connecting to the **SMTPServer** an AUTH or CRAM-MD5 (depending on **SMTPAuthMechanism**) command is sent for user authentication. **SMTPPort**: The SMTP mail port to be used, if different than MailServer.The mail port to be used for SMTP (or POP/S). For implicit SSL, use port 465. **SMTPServer**: The SMTP server to be used, if different than MailServer.The mail server to be used for SMTP (or SMTP/S), in case different than **MailServer**. **SMTPSSLStartMode**: Determines how SSL negotiation starts with the SMTP server.0 **ssl Automatic** 1 **ssl Implicit** 2 **ssl Explicit** 3 **ssl None** Default These modes have the same interpretation as defined by the property **SSLStartMode**. **SMTPUser**: The user name used for authentication.If SMTPUser is set to a non empty string, then when connecting to the **SMTPServer** an AUTH or CRAM-MD5 (depending on **SMTPAuthMechanism**) command is sent for user authentication. ### SSL Config Settings **LogSSLPackets**: Controls whether SSL packets are logged when using the internal security API.When [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLStatus](#sslstatus-event-as1sender-component) event, which will fire each time an SSL packet is sent or received. Enabling this configuration setting has no effect if [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) is set to *Internal*, this configuration setting specifies one or more CA certificates to be included with the SSLCert 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 [SSLStatus](#sslstatus-event-as1sender-component) 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 SSLAuthenticateClients 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 [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) 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, [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLServerAuthentication](#sslserverauthentication-event-as1sender-component) 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 [SSLServerAuthentication](#sslserverauthentication-event-as1sender-component) event. If set to True, all certificates returned by the server will be present in the Encoded parameter of the [SSLServerAuthentication](#sslserverauthentication-event-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) 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 [SSLProvider](#sslprovider-property-as1sender-component) 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 ### 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 ([AS1Sender](#as1sender-component) Component) ### AS1Sender Errors | | | | --- | --- | | 501 | Unable to parse the receipt. | | 502 | The receipt is signed with an unsupported signature format (details follow). | | 511 | Unsupported compression algorithm requested. | | 521 | A Message Integrity Check was requested, but not provided in the MDN. | | 522 | The Message Integrity Check returned in the MDN is incorrect. | | 523 | Unable to parse Message Integrity Check. | | 524 | Unrequested hashing algorithm used (check MDNOptions). | | 525 | The Message ID returned in the MDN does not match. | | 531 | The receipt was unsigned, and a signed receipt was expected. | | 532 | The receipt signature could not be verified. | | 533 | An MDN was expected, but was not returned. | | 600 | Failure reported in MDN: Unsupported signing protocol. | | 601 | Failure reported in MDN: Unsupported MIC algorithms. | | 602 | Failure reported in MDN: Other (details follow). | | 611 | Error reported in MDN: Decryption failed. | | 612 | Error reported in MDN: Authentication failed. | | 613 | Error reported in MDN: Could not verify content integrity. | | 614 | Error reported in MDN: Unexpected processing error. | | 615 | Error reported in MDN: Other (details follow). | | 621 | Warning reported in MDN: Authentication failed, processing continued by receiver. | | 622 | Warning reported in MDN: Other (details follow). | | 831 | I/O Error (details follow). | ### POP Errors | | | | --- | --- | | 116 | MailPort cannot be zero.
