# AS1Receiver Class The AS1Receiver class is used to process AS1 messages and generate receipts. ## Syntax ```text class ipworksedi.AS1Receiver ``` ## Remarks The AS1Receiver class allows you to receive AS1 messages as specified in RFC 3335. The class can act as an email client, decrypt and verify incoming messages, generate receipts including Message Disposition Notifications (MDNs), and send them over SMTP/S. **Basic Operation** You should first log in to your mail server by setting [mail_server](#mail_server-property), [user](#user-property), and [password](#password-property), and invoking [connect](#connect-method). You may then navigate your mail inbox by setting [mail_message_number](#mail_message_number-property), and inspecting properties such as [mail_message_from](#mail_message_from-property), etc. When you find the desired file you may download it by invoking [read_request](#read_request-method). Alternatively, you may acquire the AS1 data by other means and directly set [request](#request-property) and request_headers. [read_request](#read_request-method) (or parse_headers) will determine information such as [from_address](#from_address-property) and [send_to](#send_to-property), which will allow you to set the appropriate certificates. You may specify your certificate with the certificate property, and your trading partner's (signing) certificate with the signer_cert property. Then, invoke [process_request](#process_request-method) to process the request and generate the MDN receipt as specified in RFC 3335. If the request was processed successfully, [edi_data](#edi_data-property) will contain the transmitted EDI data. If a problem occurred, [edi_data](#edi_data-property) will not be populated and an exception will be thrown. In either case mdn_receipt will contain the RFC-compliant receipt, which should be returned to the client. The mdn_receipt may be returned over SMTP/S by invoking [send_response](#send_response-method). In case the server address for incoming mail is different than that for outgoing mail you should use [config](#config-method) to configure this. To create log files, set [log_directory](#log_directory-property) prior to invoking [process_request](#process_request-method). This will log all incoming and outgoing data, and will also write the received EDI files to disk. **Example** ```text AS1Receiver1.User = "myusername" AS1Receiver1.Password = "mypassword" AS1Receiver1.MailServer = "1.2.3.4" AS1Receiver1.Connect() // You may need to search the server for received files at this point AS1Receiver1.MessageNumber = 1; // You may check properties such as MailMessageFrom, etc. AS1Receiver1.ReadRequest() AS1Receiver1.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "\\my_server_directory\\my_pfx_file.pfx", "my password", "CN=Me"); AS1Receiver1.SignerCert = (base 64 encoded certificate); AS1Receiver1.LogDirectory = "c:\\my_server_directory\\my_log_directory"; AS1Receiver1.ProcessRequest(); AS1Receiver1.SendResponse(); AS1Receiver1.Disconnect(); ``` Additional functionality allows the user to examine details of the client's request, to permit certain types of errors, or to customize the outgoing MDN.

Code Example. SSH Authentication with Security Key (without CertMgr): Alternatively, collect the necessary data using the [CertMgr](#CertMgr) class by calling the [list_store_certificates](#CertMgr_m_ListStoreCertificates) method after setting the corresponding properties accordingly. The certificate information returned in the [on_cert_list](#CertMgr_e_CertList) event's CertEncoded parameter may be saved for later use. When using a certificate obtained with this approach, pass the previously saved security key information as the [signer_cert_store](#signer_cert_store-property) and set [signer_cert_store_password](#signer_cert_store_password-property) to the PIN.

This property is read-only. # ssl_server_cert_store_type property The type of certificate store for this certificate. ## Syntax ```text def get_ssl_server_cert_store_type() -> int: ... ssl_server_cert_store_type = property(get_ssl_server_cert_store_type, None) ``` ## Possible Values ```text 0 # User1 # Machine2 # PFXFile3 # PFXBlob4 # JKSFile5 # JKSBlob6 # PEMKeyFile7 # PEMKeyBlob8 # PublicKeyFile9 # PublicKeyBlob10 # SSHPublicKeyBlob11 # P7BFile12 # P7BBlob13 # SSHPublicKeyFile14 # PPKFile15 # PPKBlob16 # XMLFile17 # XMLBlob18 # JWKFile19 # JWKBlob20 # SecurityKey21 # BCFKSFile22 # BCFKSBlob23 # PKCS1199 # Auto ``` ## Default Value 0 ## Remarks The type of certificate store for this certificate. The class supports both public and private keys in a variety of formats. When the *cstAuto* value is used, the class will automatically determine the type. This property can take one of the following values: ```csharp sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll", "123456", // PIN "CN=cert_subject"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22); ``` ```csharp certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; // PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22); ``` | | | | --- | --- | | 0 (cstUser - default) | For Windows, this specifies that the certificate store is a certificate store owned by the current user. NOTE: This store type is not available in Java. | | 1 (cstMachine) | For Windows, this specifies that the certificate store is a machine store. NOTE: This store type is not available in Java. | | 2 (cstPFXFile) | The certificate store is the name of a PFX (PKCS#12) file containing certificates. | | 3 (cstPFXBlob) | The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format. | | 4 (cstJKSFile) | The certificate store is the name of a Java Key Store (JKS) file containing certificates. NOTE: This store type is only available in Java. | | 5 (cstJKSBlob) | The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. NOTE: This store type is only available in Java. | | 6 (cstPEMKeyFile) | The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate. | | 7 (cstPEMKeyBlob) | The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate. | | 8 (cstPublicKeyFile) | The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate. | | 9 (cstPublicKeyBlob) | The certificate store is a string (binary or Base64-encoded) that contains a PEM- or DER-encoded public key certificate. | | 10 (cstSSHPublicKeyBlob) | The certificate store is a string (binary or Base64-encoded) that contains an SSH-style public key. | | 11 (cstP7BFile) | The certificate store is the name of a PKCS#7 file containing certificates. | | 12 (cstP7BBlob) | The certificate store is a string (binary) representing a certificate store in PKCS#7 format. | | 13 (cstSSHPublicKeyFile) | The certificate store is the name of a file that contains an SSH-style public key. | | 14 (cstPPKFile) | The certificate store is the name of a file that contains a PPK (PuTTY Private Key). | | 15 (cstPPKBlob) | The certificate store is a string (binary) that contains a PPK (PuTTY Private Key). | | 16 (cstXMLFile) | The certificate store is the name of a file that contains a certificate in XML format. | | 17 (cstXMLBlob) | The certificate store is a string that contains a certificate in XML format. | | 18 (cstJWKFile) | The certificate store is the name of a file that contains a JWK (JSON Web Key). | | 19 (cstJWKBlob) | The certificate store is a string that contains a JWK (JSON Web Key). | | 21 (cstBCFKSFile) | The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). NOTE: This store type is only available in Java and .NET. | | 22 (cstBCFKSBlob) | The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. NOTE: This store type is only available in Java and .NET. | | 23 (cstPKCS11) | The certificate is present on a physical security key accessible via a PKCS#11 interface. To use a security key, create a new [Certificate](#Type_Certificate) object and pass cstPKCS11 as the [ssl_server_cert_store_type](#ssl_server_cert_store_type-property), the full path of the PKCS#11 DLL as the [ssl_server_cert_store](#ssl_server_cert_store-property), and the PIN as the [ssl_server_cert_store_password](#ssl_server_cert_store_password-property). Code Example. SSH Authentication with Security Key (without CertMgr): Alternatively, collect the necessary data using the [CertMgr](#CertMgr) class by calling the [list_store_certificates](#CertMgr_m_ListStoreCertificates) method after setting the corresponding properties accordingly. The certificate information returned in the [on_cert_list](#CertMgr_e_CertList) event's CertEncoded parameter may be saved for later use. When using a certificate obtained with this approach, pass the previously saved security key information as the [ssl_server_cert_store](#ssl_server_cert_store-property) and set [ssl_server_cert_store_password](#ssl_server_cert_store_password-property) to the PIN. Code Example. SSH Authentication with Security Key (with CertMgr): | | 99 (cstAuto) | The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically. | This property is read-only. # ssl_server_cert_subject property The subject of the certificate used for client authentication. ## Syntax ```text def get_ssl_server_cert_subject() -> str: ... ssl_server_cert_subject = property(get_ssl_server_cert_subject, None) ``` ## Default Value "" ## Remarks The subject of the certificate used for client authentication. 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. # ssl_server_cert_subject_alt_names property Comma-separated lists of alternative subject names for the certificate. ## Syntax ```text def get_ssl_server_cert_subject_alt_names() -> str: ... ssl_server_cert_subject_alt_names = property(get_ssl_server_cert_subject_alt_names, None) ``` ## Default Value "" ## Remarks Comma-separated lists of alternative subject names for the certificate. This property is read-only. # ssl_server_cert_thumbprint_md5 property The MD5 hash of the certificate. ## Syntax ```text def get_ssl_server_cert_thumbprint_md5() -> str: ... ssl_server_cert_thumbprint_md5 = property(get_ssl_server_cert_thumbprint_md5, None) ``` ## Default Value "" ## Remarks The MD5 hash of the certificate. It is primarily used for X.509 certificates. If the hash does not already exist, it is automatically computed. This property is read-only. # ssl_server_cert_thumbprint_sha1 property The SHA-1 hash of the certificate. ## Syntax ```text def get_ssl_server_cert_thumbprint_sha1() -> str: ... ssl_server_cert_thumbprint_sha1 = property(get_ssl_server_cert_thumbprint_sha1, None) ``` ## Default Value "" ## Remarks The SHA-1 hash of the certificate. It is primarily used for X.509 certificates. If the hash does not already exist, it is automatically computed. This property is read-only. # ssl_server_cert_thumbprint_sha256 property The SHA-256 hash of the certificate. ## Syntax ```text def get_ssl_server_cert_thumbprint_sha256() -> str: ... ssl_server_cert_thumbprint_sha256 = property(get_ssl_server_cert_thumbprint_sha256, None) ``` ## Default Value "" ## Remarks The SHA-256 hash of the certificate. It is primarily used for X.509 certificates. If the hash does not already exist, it is automatically computed. This property is read-only. # ssl_server_cert_usage property The text description of UsageFlags . ## Syntax ```text def get_ssl_server_cert_usage() -> str: ... ssl_server_cert_usage = property(get_ssl_server_cert_usage, None) ``` ## Default Value "" ## Remarks The text description of [ssl_server_cert_usage_flags](#ssl_server_cert_usage_flags-property). This value will be one or more of the following strings and will be separated by commas: - Digital Signature - Non-Repudiation - Key Encipherment - Data Encipherment - Key Agreement - Certificate Signing - CRL Signing - Encipher Only If the provider is OpenSSL, the value is a comma-separated list of X.509 certificate extension names. This property is read-only. # ssl_server_cert_usage_flags property The flags that show intended use for the certificate. ## Syntax ```text def get_ssl_server_cert_usage_flags() -> int: ... ssl_server_cert_usage_flags = property(get_ssl_server_cert_usage_flags, None) ``` ## Default Value 0 ## Remarks The flags that show intended use for the certificate. The value of [ssl_server_cert_usage_flags](#ssl_server_cert_usage_flags-property) is a combination of the following flags: | | | | --- | --- | | 0x80 | Digital Signature | | 0x40 | Non-Repudiation | | 0x20 | Key Encipherment | | 0x10 | Data Encipherment | | 0x08 | Key Agreement | | 0x04 | Certificate Signing | | 0x02 | CRL Signing | | 0x01 | Encipher Only | Please see the [ssl_server_cert_usage](#ssl_server_cert_usage-property) property for a text representation of [ssl_server_cert_usage_flags](#ssl_server_cert_usage_flags-property). This functionality currently is not available when the provider is OpenSSL. This property is read-only. # ssl_server_cert_version property The certificate's version number. ## Syntax ```text def get_ssl_server_cert_version() -> str: ... ssl_server_cert_version = property(get_ssl_server_cert_version, None) ``` ## Default Value "" ## Remarks The certificate's version number. The possible values are the strings "V1", "V2", and "V3". This property is read-only. # ssl_start_mode property Determines how the class starts the SSL negotiation. By default, SSL will not be used. ## Syntax ```text def get_ssl_start_mode() -> int: ... def set_ssl_start_mode(value: int) -> None: ... ssl_start_mode = property(get_ssl_start_mode, set_ssl_start_mode) ``` ## 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 - default) | If the remote port is set to the standard plaintext port of the protocol (where applicable), the class 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 class will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS. | | 3 (sslNone) | No SSL negotiation, no SSL security. All communication will be in plaintext mode. | # user property The username for your incoming mail server. ## Syntax ```text def get_user() -> str: ... def set_user(value: str) -> None: ... user = property(get_user, set_user) ``` ## Default Value "" ## Remarks The username for your incoming mail server. Set this before invoking [connect](#connect-method). # config method Sets or retrieves a configuration setting. ## Syntax ```text def config(configuration_string: str) -> str: ... ``` ## Remarks config is a generic method available in every class. It is used to set and retrieve [configuration settings](#as1receiver-config-settings) for the class. These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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](#as1receiver-config-settings), you must call *Config("PROPERTY")*. The value will be returned as a string. # connect method Connects to the incoming mail server. ## Syntax ```text def connect() -> None: ... ``` ## Remarks Connects to the incoming mail server specified by [mail_server](#mail_server-property). You must set [user](#user-property) and [password](#password-property) prior to calling connect. The connection will be maintained until you call [disconnect](#disconnect-method). If you wish to connect in SSL you should first set the [ssl_start_mode](#ssl_start_mode-property) 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. # create_mdn_receipt method Creates MDNReceipt . ## Syntax ```text def create_mdn_receipt(headers: str, mdn: str, message: str) -> None: ... ``` ## Remarks **CreateMDNReceipt** may be invoked after [parse_request](#parse_request-method) to create an MDN-based receipt. The receipt will report success or failure depending on [ErrorReportingFlags](#ErrorReportingFlags) and the success or failure of [parse_request](#parse_request-method). This method populates mdn_receipt with a new **MDNReceipt**. The *Headers*, *MDN*, and *Message* parameters can be used to further customize the receipt, or empty string ("") parameters may be set to use the class generated defaults. *Headers* will set additional transport headers to be sent with the receipt (in the HTTP or SMTP headers of the signed receipt). *MDN* can be used to append additional headers to the Message Disposition Notification portion of the MDN Receipt. If *MDN* is set to a value prefixed with an at sign ("@"), the at sign will be removed and the specified MDN will be used in the receipt in place of the component generated value. *Message* will set the human-readable portion of the receipt, and should describe any error conditions that may have occurred. # delete_message method Deletes the message specified by MailMessageNumber . ## Syntax ```text def delete_message() -> None: ... ``` ## Remarks Requests that the [mail_server](#mail_server-property) delete the message specified by [mail_message_number](#mail_message_number-property). The message will not actually be deleted until the connection is closed. # disconnect method Disconnects from the incoming mail server. ## Syntax ```text def disconnect() -> None: ... ``` ## Remarks Disconnects from the incoming mail server specified by [mail_server](#mail_server-property). # parse_request method Parses the EDI message and determines the EDIData . ## Syntax ```text def parse_request() -> None: ... ``` ## Remarks Processes the EDI message in the request (either from the HTTP context, or as given by [request](#request-property) and possibly [request_headers_string](#request_headers_string-property)). If the message is encrypted, it will be decrypted with the certificate specified in certificate. If it is signed, the signature will be verified against the certificate specified in signer_cert. If the message is scanned without difficulty, [edi_data](#edi_data-property) will be populated. If a problem occurs, an exception will be thrown. This might occur if the client used or requested unsupported algorithms or data formats. In this case, [edi_data](#edi_data-property) will not be determined. The class may be configured to ignore certain errors by setting [ErrorProcessingFlags](#ErrorProcessingFlags). This will allow the message to be processed and [edi_data](#edi_data-property) to be determined. If any errors occur, an exception will be thrown and the [scan_result](#scan_result-property) property will reflect the error condition. Whether or not an exception is thrown, an mdn_receipt may be generated by invoking [create_mdn_receipt](#create_mdn_receipt-method). In the case of a successful scan mdn_receipt will report the success, otherwise the receipt will provide information to the client about the error. [process_request](#process_request-method) may be used to scan and create the receipt in one step. [read_request](#read_request-method) may be used to scan the request headers only to obtain details that can be used to configure the correct settings for the partner. # process_queue method Send the messages queued for sending. ## Syntax ```text def process_queue(directory: str) -> None: ... ``` ## Remarks Invoking process_queue sends the messages that have been queued by [queue](#queue-method). # process_request method Processes the EDI data, and generates the receipt. ## Syntax ```text def process_request() -> None: ... ``` ## Remarks Invoking **ProcessRequest** automates the entire AS2 server process. The method scans the request, determines the [edi_data](#edi_data-property), and generates the mdn_receipt. In a server environment the receipt may be returned by invoking [send_response](#send_response-method). The method's functionality is the same as the combined functionality of [parse_request](#parse_request-method) and [create_mdn_receipt](#create_mdn_receipt-method). The method's operation is controlled by [ErrorProcessingFlags](#ErrorProcessingFlags) and [ErrorReportingFlags](#ErrorReportingFlags), and [scan_result](#scan_result-property) will be populated as in [parse_request](#parse_request-method). The method will throw an exception, as [parse_request](#parse_request-method) does, if a problem is found while processing the request. However, if the problem does not prevent an MDN from being generated, mdn_receipt will still be generated before the exception is thrown. In all cases, the receipt will be suitable for returning to the client. If an exception is thrown, the mdn_receipt will provide more detail on the cause of the error. The class will populate [edi_data](#edi_data-property) if no errors occurred scanning the request, or if [ErrorProcessingFlags](#ErrorProcessingFlags) had been previously configured to allow the error. # query_message_size method Returns the size in bytes of the current message. ## Syntax ```text def query_message_size() -> int: ... ``` ## Remarks This method queries the server for the size in bytes of the message specified by [mail_message_number](#mail_message_number-property). The method returns the size (in bytes) of the message. # query_message_uid method Returns the unique identifier of the message as specified by the server. ## Syntax ```text def query_message_uid() -> str: ... ``` ## Remarks This method returns the unique identifier of the message specified by [mail_message_number](#mail_message_number-property). # queue method Prepares and queues the message to the specified directory. ## Syntax ```text def queue(directory: str) -> None: ... ``` ## Remarks Invoking queue will prepare and queue the AS1 message. It will be signed if signing_cert is set, encrypted if recipient_cert is set, and compressed if [compression_format](#compression_format-property) is set. A receipt will be requested if [mdn_to](#mdn_to-property) is set. The queued message can then be sent by invoking [process_queue](#process_queue-method). # read_request method Reads the AS1 request from the mail server. ## Syntax ```text def read_request() -> None: ... ``` ## Remarks In the **Java** edition, read_request will retrieve the file specified by [mail_message_number](#mail_message_number-property) from the mail server. The request will be stored in [request](#request-property) and the headers in request_headers. The headers will also be parsed as in parse_headers, and the appropriate values of [from_address](#from_address-property), [send_to](#send_to-property), etc., will be populated. After looking up and setting your trading partner information (such as certificates) you may then call [process_request](#process_request-method). # reset method Resets the state of the control. ## Syntax ```text def reset() -> None: ... ``` ## Remarks **Reset** resets the state of the class. All properties will be set to their default values. # select_mail_message method Selects and obtains information about the specified message. ## Syntax ```text def select_mail_message() -> None: ... ``` ## Remarks This method selects the message specified by [mail_message_number](#mail_message_number-property) and retrieves information about it. After calling this method properties such as [mail_message_headers](#mail_message_headers-property), [mail_message_date](#mail_message_date-property), [mail_message_from](#mail_message_from-property), etc., allow you to determine if this message is an AS1 message. Additional properties are exposed via the [config](#config-method) method. If this message is an AS1 transmission, you may use [read_request](#read_request-method) to read it. The [request](#request-property) and request_headers properties will contain the request and request headers, and [from_address](#from_address-property) will be populated with the originator of the request. You may then set trading partner information and invoke [process_request](#process_request-method) to process the request. # send_response method Sends the MDN receipt. ## Syntax ```text def send_response() -> None: ... ``` ## Remarks Sends the MDN receipt specified by mdn_receipt. The receipt will be created when invoking [process_request](#process_request-method) or [create_mdn_receipt](#create_mdn_receipt-method). By default, the class will assume that the SMTP server is located at the same address as the incoming mail server. The [SMTPServer](#SMTPServer) and [SMTPPort](#SMTPPort) settings can be used to set a different address or to use a non default port. A response will only be sent if requested by the client. The MDN will be directed to the [from_address](#from_address-property) address that sent the request, regardless of the [mdn_to](#mdn_to-property) value. If [mdn_to](#mdn_to-property) is empty, this method will do nothing. # on_connection_status event Fired to indicate changes in the connection state. ## Syntax ```text class AS1ReceiverConnectionStatusEventParams(object): @property def connection_event() -> str: ... @property def status_code() -> int: ... @property def description() -> str: ... # In class AS1Receiver: @property def on_connection_status() -> Callable[[AS1ReceiverConnectionStatusEventParams], None]: ... @on_connection_status.setter def on_connection_status(event_hook: Callable[[AS1ReceiverConnectionStatusEventParams], None]) -> None: ... ``` ## 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 Fired when the message text completes transferring. ## Syntax ```text class AS1ReceiverEndTransferEventParams(object): # In class AS1Receiver: @property def on_end_transfer() -> Callable[[AS1ReceiverEndTransferEventParams], None]: ... @on_end_transfer.setter def on_end_transfer(event_hook: Callable[[AS1ReceiverEndTransferEventParams], None]) -> None: ... ``` ## Remarks Fired when the message text completes transferring (on either a send or receive). # on_error event Fired when information is available about errors during data delivery. ## Syntax ```text class AS1ReceiverErrorEventParams(object): @property def error_code() -> int: ... @property def description() -> str: ... # In class AS1Receiver: @property def on_error() -> Callable[[AS1ReceiverErrorEventParams], None]: ... @on_error.setter def on_error(event_hook: Callable[[AS1ReceiverErrorEventParams], None]) -> None: ... ``` ## Remarks The on_error event is fired in case of exceptional conditions during message processing. Normally the class 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](#as1receiver-errors) section. # on_header event This event is fired for every message header being retrieved. ## Syntax ```text class AS1ReceiverHeaderEventParams(object): @property def field() -> str: ... @property def value() -> str: ... # In class AS1Receiver: @property def on_header() -> Callable[[AS1ReceiverHeaderEventParams], None]: ... @on_header.setter def on_header(event_hook: Callable[[AS1ReceiverHeaderEventParams], None]) -> None: ... ``` ## 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). # on_launch_browser event Fires before launching a browser with the authorization URL. ## Syntax ```text class AS1ReceiverLaunchBrowserEventParams(object): @property def url() -> str: ... @url.setter def url(value) -> None: ... @property def command() -> str: ... @command.setter def command(value) -> None: ... # In class AS1Receiver: @property def on_launch_browser() -> Callable[[AS1ReceiverLaunchBrowserEventParams], None]: ... @on_launch_browser.setter def on_launch_browser(event_hook: Callable[[AS1ReceiverLaunchBrowserEventParams], None]) -> None: ... ``` ## Remarks When the client_profile property is set to ocpApplication and get_authorization is called, the class will fire this event with the *command*, which will be executed by the class. 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 class 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 Fired with log information while processing a message. ## Syntax ```text class AS1ReceiverLogEventParams(object): @property def log_type() -> str: ... @property def log_message() -> bytes: ... # In class AS1Receiver: @property def on_log() -> Callable[[AS1ReceiverLogEventParams], None]: ... @on_log.setter def on_log(event_hook: Callable[[AS1ReceiverLogEventParams], None]) -> None: ... ``` ## Remarks This event is fired once for each log message generated by the class. 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" This event fires once for each log message generated by the class. The verbosity is controlled by the [LogLevel](#LogLevel) setting. Log messages available through this event correspond to log files written to [log_directory](#log_directory-property). This event provides a way to obtain log messages without relying on files on disk. This event fires regardless of the value of [log_directory](#log_directory-property) (i.e. when [log_directory](#log_directory-property) 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.

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 class code). | # on_signer_cert_info event This event is fired during verification of the signed message. ## Syntax ```text class AS1ReceiverSignerCertInfoEventParams(object): @property def issuer() -> str: ... @property def serial_number() -> str: ... @property def subject_key_identifier() -> str: ... @property def cert_encoded() -> bytes: ... # In class AS1Receiver: @property def on_signer_cert_info() -> Callable[[AS1ReceiverSignerCertInfoEventParams], None]: ... @on_signer_cert_info.setter def on_signer_cert_info(event_hook: Callable[[AS1ReceiverSignerCertInfoEventParams], None]) -> None: ... ``` ## Remarks During verification, this event will be raised while parsing the signer's certificate information. The parameters that are populated depend on the options used when the message was originally signed. This information may be used to select the correct certificate for signer_cert to verify the signature. The following parameters may be populated: *Issuer* specifies the subject of the issuer of the certificate used to sign the message. *SerialNumber* is the serial number of the certificate used to sign the message. *SubjectKeyIdentifier* is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string. *CertEncoded* is the PEM (Base64 encoded) public certificate needed to verify the signature. NOTE: When this value is present, the class will automatically use this value to perform signature verification. The signer_cert property may be set from within this event. In this manner, the decision of which signer certificate to load may be delayed until the parameters of this event are inspected and the correct certificate can be located and loaded. # on_ssl_server_authentication event Fired after the server presents its certificate to the client. ## Syntax ```text class AS1ReceiverSSLServerAuthenticationEventParams(object): @property def cert_encoded() -> bytes: ... @property def cert_subject() -> str: ... @property def cert_issuer() -> str: ... @property def status() -> str: ... @property def accept() -> bool: ... @accept.setter def accept(value) -> None: ... # In class AS1Receiver: @property def on_ssl_server_authentication() -> Callable[[AS1ReceiverSSLServerAuthenticationEventParams], None]: ... @on_ssl_server_authentication.setter def on_ssl_server_authentication(event_hook: Callable[[AS1ReceiverSSLServerAuthenticationEventParams], None]) -> None: ... ``` ## 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 Fired when secure connection progress messages are available. ## Syntax ```text class AS1ReceiverSSLStatusEventParams(object): @property def message() -> str: ... # In class AS1Receiver: @property def on_ssl_status() -> Callable[[AS1ReceiverSSLStatusEventParams], None]: ... @on_ssl_status.setter def on_ssl_status(event_hook: Callable[[AS1ReceiverSSLStatusEventParams], None]) -> None: ... ``` ## Remarks The event is fired for informational and logging purposes only. This event tracks the progress of the connection. # on_start_transfer event Fired when the message text starts transferring (on either a send or receive). ## Syntax ```text class AS1ReceiverStartTransferEventParams(object): # In class AS1Receiver: @property def on_start_transfer() -> Callable[[AS1ReceiverStartTransferEventParams], None]: ... @on_start_transfer.setter def on_start_transfer(event_hook: Callable[[AS1ReceiverStartTransferEventParams], None]) -> None: ... ``` ## Remarks Fired when the message text starts transferring (on either a send or receive). # on_transfer event Fired while the message text gets transferred to or from MailServer . ## Syntax ```text class AS1ReceiverTransferEventParams(object): @property def bytes_transferred() -> int: ... # In class AS1Receiver: @property def on_transfer() -> Callable[[AS1ReceiverTransferEventParams], None]: ... @on_transfer.setter def on_transfer(event_hook: Callable[[AS1ReceiverTransferEventParams], None]) -> None: ... ``` ## Remarks Fired while the message text gets transferred to or from [mail_server](#mail_server-property). # AS1Receiver Config Settings The class 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 class, access to these *internal properties* is provided through the [config](#config-method) method. ### AS1Receiver Config Settings **FileName**: The filename of the EDI Data.This is a read only setting that gives the filename of the content received. ### 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 [ssl_provider](#ssl_provider-property) 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) 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) 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 class 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 class is the same. **SSLCACertFilePaths**: The paths to CA certificate files on Unix/Linux.This configuration setting specifies the paths on disk to CA certificate files on Unix/Linux. The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found, the CA certificates within the file will be loaded and used to determine the validity of server or client certificates. The default value is as follows: */etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem* **SSLCACerts**: A newline separated list of CA certificates to be included when performing an SSL handshake.When [ssl_provider](#ssl_provider-property) 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 class will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class 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 class fails with an error. When set to 0 (default), the CRL check will not be performed by the class. 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 class will use OCSP to check the validity of the server certificate. If set to 1 or 2, the class will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The class 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 class fails with an error. When set to 0 (default), the class 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) 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 class 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) 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) 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) 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) 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 class will first try to use the platform TLS 1.3 implementation when the [ssl_provider](#ssl_provider-property) 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) 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 class when the [ssl_provider](#ssl_provider-property) 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) 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) 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) 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) 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) 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 class 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 class will only append, it will not overwrite previous values. NOTE: This configuration setting is applicable only when [ssl_provider](#ssl_provider-property) 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) is set to *Internal* and [SSLEnabledProtocols](#SSLEnabledProtocols) is set to allow TLS 1.2. When specified the class 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 class 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) 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*. **ProcessIdleEvents**: Whether the class uses its internal event loop to process events when the main thread is idle.If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True. **SelectWaitMillis**: The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.If there are no events to process when do_events is called, the class will wait for the amount of time specified here before returning. The default value is 20. **UseFIPSCompliantAPI**: Tells the class whether or not to use FIPS certified APIs.When set to *True*, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries. FIPS mode can be enabled by setting the *UseFIPSCompliantAPI* configuration setting to *True*. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior. For more details, please see the [FIPS 140-2 Compliance](https://www.nsoftware.com/kb/articles/fips.rst) article. NOTE: This setting is applicable only on Windows. NOTE: Enabling FIPS compliance requires a special license; please contact [sales@nsoftware.com](mailto:sales@nsoftware.com) for details. **UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *False*, the class will use the system security libraries by default to perform cryptographic functions where applicable. Setting this configuration setting to *True* tells the class 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. # AS1Receiver Errors *Note: The starred errors may be ignored by configuring the [ErrorProcessingFlags](#ErrorProcessingFlags) and [ErrorReportingFlags](#ErrorReportingFlags) of the class.* ### AS1Receiver Errors | | | | --- | --- | | 701 | Unable to write log file. | | 711 | The incoming message was encrypted with an unknown protocol. | | 712 | Unable to decrypt message. | | 713 | Unable to decompress message. | | 732 | *Unable to verify content integrity. | | 733 | *Unsupported signature type was requested. | | 734 | *Unsupported MIC algorithm(s) were requested. | ### POP Errors | | | | --- | --- | | 116 | mail_port cannot be zero.
