AS2Sender Class

Properties   Methods   Events   Config Settings   Errors  

The AS2Sender class implements an AS2 / EDI-INT client.

Syntax

class ipworksedi.AS2Sender

Remarks

The AS2Sender component may be used to send EDI or other messages over HTTP/S, using the AS2 protocol. It may also be used to verify synchronous or asynchronous server responses.

A typical AS2 transaction is as follows:

(1) The sender sends an EDI document to the receiver using HTTP or HTTPS. Typically the document will be signed and encrypted (particularly if 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, as2_from and as2_to, url, and edi_data. The post 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 class will apply message security if the appropriate certificates are specified. To sign the data, set signing_cert. To encrypt, set recipient_certs. If the recipient uses different certificates for signing and encryption it will also be necessary to set receipt_signer_cert.

SSL will also be used if the scheme in url is "https". If your trading partner is using a self-signed certificate, it will be necessary to set ssl_accept_server_cert or trap the on_ssl_server_authentication event to accept the certificate.

The message may also be compressed by setting compression_format.

To request a receipt, or Message Disposition Notification (MDN), simply set the mdn_to property. The mdn_options property may be used to customize the request. By default, the class will request a signed MDN over an SHA1 hash.

The class supports both synchronous and asynchronous MDN receipt delivery. By default, the class requests synchronous MDN receipt delivery, and the MDN will be returned in the HTTP reply. To request asynchronous MDN delivery, set the mdn_delivery_option to the URL where MDN's are to be delivered.

The HTTP reply will automatically be processed by the class. If an MDN was requested, post will validate the MDN and (if signed) establish non-repudiation of receipt. Any errors or warnings will cause the class to throw an exception.

In either case, after the EDI transaction is processed successfully, the mdn_receipt will be populated with the appropriate values.

Validating Asynchronous MDNs

The class may also be used to process and verify asynchronous MDNs. To do this, you should invoke read_async_receipt. This will read the receipt from the current HTTP context (or from mdn_receipt, if set manually), and allow you to determine your trading partner's identity and the message ID. You should then set receipt_signer_cert and original_content_mic, and finally invoke verify_receipt.

The class will write multiple log file for each transmission, with separate extensions for each type of data:

Status (.log)Contains information on applied security options and pass/fail status of transmission
Request (.req)Contains the outgoing request, after security options have been applied
Payload (.dat)Contains log of unsecured payload prior to transmission
MDN Receipt (.mdn)For synchronous requests or asynchronous receipts verified with verify_receipt, contains MDN receipt.
Error (.err)This is only written in an error is encountered, containing the error.

One or more of these logs may be disabled by setting the LogOptions configuration setting.

log_directory supports several macros that can be used to specify a unique directory path. If the path specified does not already exist, the class will attempt to create the directory. The following macros are supported:

%MessageID%The MessageID of the AS2 transmission, after it is generated.
%AS2From%The AS2-From field in the transmission
%OriginalMessageID%In MDN Receipts, the MessageID of the transmission that the receipt is for. You can use this to pair asynchronous MDN receipt logs with their transmissions
%date:format%%Format% is a platform-specific date/time formatting string. For example:

The filenames will be chosen automatically by the class. 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 log_file will contain the name of the files just written, minus the extension.

If logs cannot be written an exception will be thrown.

log_file Property

The log file written.

Syntax

def get_log_file() -> str: ...

log_file = property(get_log_file, None)

Default Value

""

Remarks

If log_directory is specified a log file will be written in the specified directory and log_file will contain the full path and name of the files written, minus the extension.

The class will write multiple log files for each transmission, with separate extensions for each type of data:

Status (.log)Contains information on applied security options and pass/fail status of transmission
Request (.req)Contains the outgoing request, after security options have been applied
Payload (.dat)Contains the unsecured payload data prior to transmission
MDN Receipt (.mdn)For synchronous requests or asynchronous receipts verified with verify_receipt. This contains the MDN receipt.
Error (.err)This is only written if an error is encountered and will contain the error.

This property is read-only.

mdn_delivery_option Property

mdn_delivery_option = property(get_mdn_delivery_option, set_mdn_delivery_option)

Default Value

""

Remarks

The default mode of operation is for the receipt to be returned synchronously within the HTTP reply. By specifying a valid URL, the user may request asynchronous delivery instead. The URL indicates the destination for the reply, and may use any appropriate protocol, such as "http", "https", or "mailto".

If mdn_delivery_option is set to an empty string, the receipt will be returned synchronously, and will be processed automatically by the class. Clients requesting asynchronous delivery should provide their own processing for reading receipts.

mdn_options Property

Used to indicate the options requested for the MDN receipt.

Syntax

def get_mdn_options() -> str: ...
def set_mdn_options(value: str) -> None: ...

mdn_options = property(get_mdn_options, set_mdn_options)

Default Value

"signed-receipt-protocol=optional, pkcs7-signature; signed-receipt-micalg=optional, sha-256"

Remarks

By default, the class will request that the MDN be signed with a PKCS#7 signature over a SHA-256 hash, which is the industry standard.

Set mdn_options to an empty string to request an unsigned receipt.

This property will automatically be updated when signature_algorithm is set. Normally you will not need to set this property, however you can set a value here to override the automatically generated value.

The string format is that of the Disposition-Notification-Options HTTP header, as specified in RFC 3335. As a form of shorthand, you may set this property to "sha1", "sha-256", or "md5" to request the indicated hash algorithm.

mdn_receipt_content Property

mdn_receipt_mic_value = property(get_mdn_receipt_mic_value, None)

Default Value

""

Remarks

The Message Integrity Check(s) (one-way hash) of the original EDI message.

An MDN Receipt contains a MIC calculated over the EDI message that the receipt is in response to, to be matched on the sender side against a saved value for the original request to ensure that the integrity of the data that the receiver reports is preserved. When a signed receipt is requested, the MIC is be calculated using the algorithm used on the incoming message's signature, or SHA-1 if the incoming message is not signed.

The MIC will be base64 encoded and reported with the algorithm name as specified in RFC 3335; e.g., "w7AguNJEmhF/qIjJw6LnnA==, md5".

mdn_to Property

Used to indicate that a message disposition notification is requested.

Syntax

def get_mdn_to() -> str: ...
def set_mdn_to(value: str) -> None: ...

mdn_to = property(get_mdn_to, set_mdn_to)

Default Value

""

Remarks

If this property is set, a Disposition-Notification-To header will be added to the request, and an MDN will be requested. The value may be an email address, URL, etc., and while its presence is used to determine whether or not an MDN is sent, the value itself will typically be ignored by the server.

By default, the class will request a PKCS#7 signature and synchronous delivery. You may set mdn_delivery_option to request an asynchronous MDN, and you may set mdn_options to request a different type of signature, or no signature at all.

message_id Property

Syntax

def get_message_id() -> str: ...
def set_message_id(value: str) -> None: ...

message_id = property(get_message_id, set_message_id)

Default Value

""

Remarks

The Id format is as in RFC 2822: id-left@id-right .

A unique Id will automatically be generated on startup. Sending a message will reset id-left if the MessageId has been used in the previous message.

If you set message_id to a string of the form "@(id-right)" a unique id-left will be generated. If you set message_id to an empty string, a new message_id will be generated with the same id-right.

Default Value

""

Remarks

A MIC will be calculated over the outgoing message using the same algorithm in the signature_algorithm configuration used to sign the message. The property will be set when post (in AS3, send) is invoked, and the MIC will automatically be checked against the Original-Content-MIC in the MDN for synchronous MDNs.

The format is in RFC 3335, i.e. "w7AguNJEmhF/qIjJw6LnnA==, md5", with a newline at the end.

If you are requesting an asynchronous MDN, you must save this value externally so that it can be loaded when the MDN is received (you may also use async_mdn_info_dir).

proxy_auth_scheme Property

This property is used to tell the class which type of authorization to perform when connecting to the proxy.

The certificate information returned in the on_cert_list event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the recipient_cert_store and set recipient_cert_store_password to the PIN.

Code Example. SSH Authentication with Security Key: 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);

recipient_cert_subject Property

This is the subject of the certificate used for client authentication.

Syntax

def get_recipient_cert_subject(recipient_cert_index: int) -> str: ...
def set_recipient_cert_subject(recipient_cert_index: int, value: str) -> None: ...

Default Value

""

Remarks

This is 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=support@nsoftware.com". Common fields and their meanings are as follows:

FieldMeaning
CNCommon Name. This is commonly a hostname like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

If a field value contains a comma, it must be quoted.

The recipient_cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the recipient_cert_count property.

recipient_cert_encoded Property

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The recipient_cert_store and recipient_cert_subject properties also may be used to specify a certificate.

When recipient_cert_encoded is set, a search is initiated in the current recipient_cert_store for the private key of the certificate. If the key is found, recipient_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, recipient_cert_subject is set to an empty string.

The recipient_cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the recipient_cert_count property.

restart_directory Property

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS#11 interface.

To use a security key, the necessary data must first be collected using the CertMgr class. The list_store_certificates method may be called after setting cert_store_type to cstPKCS11, cert_store_password to the PIN, and cert_store to the full path of the PKCS#11 DLL. The certificate information returned in the on_cert_list event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the ssl_accept_server_cert_store and set ssl_accept_server_cert_store_password to the PIN.

Code Example. SSH Authentication with Security Key: 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);

This functionality currently is not available when the provider is OpenSSL.

This property is read-only.

ssl_server_cert_version Property

This property contains the certificate's version number.

Syntax

def get_ssl_server_cert_version() -> str: ...

ssl_server_cert_version = property(get_ssl_server_cert_version, None)

Default Value

""

Remarks

This property contains the certificate's version number. The possible values are the strings "V1", "V2", and "V3".

This property is read-only.

ssl_server_cert_subject Property

This is the subject of the certificate used for client authentication.

Syntax

def get_ssl_server_cert_subject() -> str: ...

ssl_server_cert_subject = property(get_ssl_server_cert_subject, None)

Default Value

""

Remarks

This is 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=support@nsoftware.com". Common fields and their meanings are as follows:

FieldMeaning
CNCommon Name. This is commonly a hostname like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

If a field value contains a comma, it must be quoted.

This property is read-only.

ssl_server_cert_encoded Property

This is the certificate (PEM/Base64 encoded).

Syntax

def get_ssl_server_cert_encoded() -> bytes: ...

ssl_server_cert_encoded = property(get_ssl_server_cert_encoded, None)

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The ssl_server_cert_store and ssl_server_cert_subject properties also may be used to specify a certificate.

When ssl_server_cert_encoded is set, a search is initiated in the current ssl_server_cert_store for the private key of the certificate. If the key is found, ssl_server_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_server_cert_subject is set to an empty string.

This property is read-only.

subject Property

The subject of the message.

Syntax

def get_subject() -> str: ...
def set_subject(value: str) -> None: ...

subject = property(get_subject, set_subject)

Default Value

""

Remarks

The optional human-readable subject of the message. Some AS2 partners will use this field to send additional information about the transmission at the transport layer.

timeout Property

This property includes the timeout for the class.

Syntax

def get_timeout() -> int: ...
def set_timeout(value: int) -> None: ...

timeout = property(get_timeout, set_timeout)

Default Value

60

Remarks

If the timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use do_events to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If timeout expires, and the operation is not yet complete, the class fails with an error.

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by timeout seconds when any amount of data is successfully sent or received.

The default value for the timeout property is 60 seconds.

url Property

The URL to which the request is made.

Syntax

def get_url() -> str: ...
def set_url(value: str) -> None: ...

url = property(get_url, set_url)

Default Value

""

Remarks

This property specifies the URL to which the request is made. SSL will be used if and only if the URL scheme is "https".

use_oaep Property

This property specifies whether or not to use Optimal Asymmetric Encryption Padding (OAEP).

Syntax

def get_use_oaep() -> bool: ...
def set_use_oaep(value: bool) -> None: ...

use_oaep = property(get_use_oaep, set_use_oaep)

Default Value

FALSE

Remarks

This property specifies whether or not to use Optimal Asymmetric Encryption Padding (OAEP). By default, this value is False and the class will use PKCS1.

To specify nondefault OAEP options, please see OAEPRSAHashAlgorithm, OAEPMGF1HashAlgorithm, and OAEPParams

use_pss Property

This property specifies whether or not RSA-PSS will be used during signing and verification.

Syntax

def get_use_pss() -> bool: ...
def set_use_pss(value: bool) -> None: ...

use_pss = property(get_use_pss, set_use_pss)

Default Value

FALSE

Remarks

This property specifies whether or not RSA-PSS will be used when signing and verifying messages. The default value is False.

user_agent Property

Information about the user agent.

Syntax

def get_user_agent() -> str: ...
def set_user_agent(value: str) -> None: ...

user_agent = property(get_user_agent, set_user_agent)

Default Value

"IPWorks EDI AS2Sender Component - www.nsoftware.com"

Remarks

You may override the default with the name and version of your software.

config Method

Sets or retrieves a configuration setting.

Syntax

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 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, you must call Config("PROPERTY"). The value will be returned as a string.

do_events Method

This method processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

When do_events is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

interrupt Method

This method interrupts the current method.

Syntax

def interrupt() -> None: ...

Remarks

If there is no method in progress, interrupt simply returns, doing nothing.

post Method

Post data to the AS2 server, and check the receipt.

Syntax

def post() -> None: ...

Remarks

Post data to the server. The reply will also be checked, and if a synchronous MDN was requested (i.e., mdn_to is not empty), it will be validated. After the method finishes, the mdn_receipt, ReceiptSigningProtocol, and receipt_signer_cert 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.

read_async_receipt Method

Reads an asynchronous MDN receipt from the current HTTP session.

Syntax

def read_async_receipt() -> None: ...

Remarks

read_async_receipt is used to read an asynchronous MDN receipt from the . The class will fetch the request stream from the HTTP session. mdn_receipt will be populated with a new instance of MDNReceipt.

reset Method

Resets the state of the control.

Syntax

def reset() -> None: ...

Remarks

Resets all HTTP headers as well as edi_data, etc. After invoking this method the class may be reused as if it were newly created.

restart Method

Restart sending of the file specified by the Etag property.

Syntax

def restart() -> None: ...

Remarks

This method should be called when using the AS2 restart functionality. When called, the class will process the file and cache the processed contents to the restart_directory. Before sending, the etag property will be populated with a unique etag which identifies the processed file.

If sending is interrupted or fails, this method should be called to restart sending of the previously processed file starting where the interruption occurred. In order to restart from the last transfer, the etag must be populated with the value from the last connection.

NOTE: When using restart functionality, the data is completely processed to the restart_directory before sending begins.

send_cem_request Method

Sends a Certificate Exchange Messaging (CEM) request.

Syntax

def send_cem_request(request_id: str) -> None: ...

Remarks

This method send the Certificate Exchange Messaging (CEM) request with the details specified in cem_details.

Certificate Exchange Messaging (CEM) allows for new certificates to be sent to a recipient and be automatically updated. This removes the requirement to manually send new certificates to a partner via email or other means. When both sides support this functionality updating certificates can be accomplished in a short period of time.

To prepare a CEM request populate the cem_details collection with at least one certificate. For instance if the certificate of the application will be updated soon, the cem_details may be populated with the corresponding public certificate to be sent to your partner. cem_details should only contain public certificates.

Set cem_respond_by_date to the date by which you expect a response. The format is of the XML standard dateTime type expressed in local time with UTC offset. For instance: "2005-08-31T00:21:00-05:00".

Optionally set cem_cert_id to a friendly identifier that the partner may use to help understand the purpose of the new certificate. For instance "New.Encryption.Cert.2014".

Set cem_response_url to the publicly accessible URL where the CEM response will be sent after the partner processes it.

The RequestId parameter uniquely identifies this CEM request and must be saved for use later when receiving the CEM response.

When calling this method the applicable cem_details properties are:

send_cem_response Method

Sends a Certificate Exchange Messaging (CEM) response.

Syntax

def send_cem_response(request_id: str) -> None: ...

Remarks

This method send the Certificate Exchange Messaging (CEM) request with the details specified in cem_details.

A CEM request must have previously been received using AS2Receiver. To send the CEM response, populate cem_details with the certificate information and decide whether to accept or reject the request. The following properties may be set to specify the certificate:

Alternatively, the certificate information may be set:

After specifying the certificate information choose whether to accept or reject the request. To accept the request set cem_accepted to True. To reject the request set cem_accepted to False and specify a reason in cem_rejection_reason.

Call send_cem_response and pass the CEM request Id that was retrieved from the request.

set_request_header Method

Allows the user to set or add arbitrary HTTP request headers.

Syntax

def set_request_header(header_name: str, header_value: str) -> None: ...

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.

set_tp_info Method

A convenient way to set AS2 communication parameters using XML strings.

Syntax

def set_tp_info(profile: str) -> None: ...

Remarks

SetTPInfo offers a convenient way to set AS2 communication parameters using XML strings. The format of the XML is the same as provided by the method GetTPInfo of AS2ProfileMgr.

The "self" information should always precede the partner information as shown below. AS2Sender as2sender = new AS2Sender(); AS2Profilemgr mgr = new AS2Profilemgr(); mgr.DataDir = @"C:\as2data"; as2sender.SetTPInfo(mgr.GetTPInfo("self")); as2sender.SetTPInfo(mgr.GetTPInfo("partnerOrg")); as2sender.EDIFile = @"C:\as2Data.x12"; as2sender.Post();

verify_receipt Method

Verifies an asynchronous MDN receipt.

Syntax

def verify_receipt() -> None: ...

Remarks

VerifyReceipt verifies the receipt in mdn_receipt against original_content_mic, message_id and the preferences specified in mdn_options. The method operates similarly to post: After the method finishes, the mdn_receipt, ReceiptSigningProtocol, and receipt_signer_cert 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.

This method should be used to verify receipts received asynchronously; i.e., not in the HTTP reply to a POST. When posting, asynchronous MDN delivery may be requested by setting mdn_delivery_option.

on_connected Event

This event is fired immediately after a connection completes (or fails).

Syntax

class AS2SenderConnectedEventParams(object):
  @property
  def status_code() -> int: ...

on_header Event

This event is fired every time a header line comes in.

Syntax

class AS2SenderHeaderEventParams(object):
  @property
  def field() -> str: ...

  @property
  def value() -> str: ...

# In class AS2Sender:
@property
def on_header() -> Callable[[AS2SenderHeaderEventParams], None]: ...
@on_header.setter
def on_header(event_hook: Callable[[AS2SenderHeaderEventParams], None]) -> None: ...

Remarks

The Field parameter contains the name of the HTTP header (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 an empty string.

Note that only the top-level headers will be returned through this event, and that they are available through the reply_headers property.

The Field parameter contains the name of the HTTP header (which is the same 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_log Event

Fired with log information while processing a message.

Syntax

class AS2SenderLogEventParams(object):

@on_log.setter
def on_log(event_hook: Callable[[AS2SenderLogEventParams], None]) -> None: ...

Remarks

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

Log messages available through this event correspond to log files written to log_directory. 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 (i.e. when log_directory 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 is True.

on_set_cookie Event

This event is fired for every cookie set by the server.

Syntax

class AS2SenderSetCookieEventParams(object):
  @property
  def name() -> str: ...

  @property
  def value() -> str: ...

  @property
  def expires() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def path() -> str: ...

  @property
  def secure() -> bool: ...

# In class AS2Sender:
@property
def on_set_cookie() -> Callable[[AS2SenderSetCookieEventParams], None]: ...
@on_set_cookie.setter
def on_set_cookie(event_hook: Callable[[AS2SenderSetCookieEventParams], None]) -> None: ...

Remarks

The on_set_cookie event is fired for every Set-Cookie: header received from the HTTP server.

The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.

The Expires parameter contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.

The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (url_server) as the cookie domain.

The Path parameter contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the Path parameter will be an empty string. The convention in this case is to use the path specified in the URL (url_path) as the cookie path.

The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class AS2SenderSSLServerAuthenticationEventParams(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 AS2Sender:
@property
def on_ssl_server_authentication() -> Callable[[AS2SenderSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[AS2SenderSSLServerAuthenticationEventParams], None]) -> None: ...

Remarks

This event is where the client can decide whether to continue with the connection process or not. 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 to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK").

on_ssl_status Event

Fired when secure connection progress messages are available.

Syntax

class AS2SenderSSLStatusEventParams(object):
  @property
  def message() -> str: ...

# In class AS2Sender:
@property
def on_ssl_status() -> Callable[[AS2SenderSSLStatusEventParams], None]: ...
@on_ssl_status.setter
def on_ssl_status(event_hook: Callable[[AS2SenderSSLStatusEventParams], 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

This event is fired when a document starts transferring (after the headers).

Syntax

class AS2SenderStartTransferEventParams(object):
  @property
  def direction() -> int: ...

# In class AS2Sender:
@property
def on_start_transfer() -> Callable[[AS2SenderStartTransferEventParams], None]: ...
@on_start_transfer.setter
def on_start_transfer(event_hook: Callable[[AS2SenderStartTransferEventParams], None]) -> None: ...

Remarks

The on_start_transfer event is fired first when the client starts sending data to the server (in a POST or PUT request) and then when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_transfer Event

This event is fired while a document transfers (delivers document).

Syntax

class AS2SenderTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def bytes_transferred() -> int: ...

  @property
  def percent_done() -> int: ...

  @property
  def text() -> bytes: ...

# In class AS2Sender:
@property
def on_transfer() -> Callable[[AS2SenderTransferEventParams], None]: ...
@on_transfer.setter
def on_transfer(event_hook: Callable[[AS2SenderTransferEventParams], None]) -> None: ...

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

AS2Sender 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 method.

AS2Sender Config Settings

AllowMDNWarnings:   Whether to fail on MDN warnings.

When processing MDNs this setting determines if the class throws an exception when a MDN warning is processed. By default this value is False and MDN warnings other than duplicate files warnings will result in an exception. If set to True all MDN warnings will be allowed and processing will continue as normal. Check MDNDisposition to process the warning manually in this case.

Authorization:   The Authorization string to be sent to the server.

If the Authorization setting contains a non-empty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

This setting is provided so that the class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The AuthScheme; setting defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization setting in the form "Basic [encoded-user-password]".

AuthScheme:   The authorization scheme to be used when server authorization is to be performed.

Use the AuthScheme property to tell the component which type of authorization to perform when the User and Password properties are set. Possible values are:

0 (default)Basic
1Digest
2Proprietary
3None
4NTLM
5Negotiate
6OAuth
By default, AuthScheme is Basic (0), and if the User and Password configuration settings are set, the component will attempt basic authentication. If AuthScheme is set to Digest (1), digest authentication will be attempted instead.

For security reasons, setting this value will clear the values of User and Password.

EncodeToTempDir:   Whether to use temporary files when creating messages.

This setting determines if temporary files are used when creating messages. By default this value is not set and messages are created in memory before posting. When working with very large files this can cause substantial memory usage. To avoid memory overhead when working with large files set this to a relative or absolute path to a directory on disk. When post is called the class will create a file in the specified directory during processing.

IgnoreLoggingErrors:   Whether to ignore errors that occur when writing to the log.

When this setting is enabled (default False), any errors that occur while writing to log files will be ignored, and no exception will be thrown. Note that this may cause logs to be incomplete or missing without any indication that an issue occurred.

IncludeHeaders:   Whether headers are included when posting to a file.

This setting determines if headers are included in the file when using PostToFile. By default this value is true. When set to False headers are not included in the content written to the file. When set to False this also allows data to be streamed directly to the file specified by PostToFile without any substantial memory overhead or the use of EncodeToTempDir. After posting to a file check the MessageHeaders to obtain the headers. This setting should only be used when PostToFile is set.

LogDebug:   Whether to log debug data.

This setting specifies whether to log debug data. When set to True the class will create additional files in the log_directory. The default value is False.

When sending, files with extensions ".input", ".sign", ".compress", and ".encrypt" may be created. When receiving, files with extensions ".input", ".verify", ".decompress", and ".decrypt" may be created.

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.

LogOptions:   The information to be written to log files.

When log_directory is set, several pieces of information are written to log files in the specified directory. Set LogOptions to one or more of the following values to control what information is written to file. When specifying multiple values, include them in the same string (i.e. "LogOptions=Status, Response, Payload"):

StatusContains information on applied security options and pass/fail status of transmission
RequestContains outgoing transmission, with applied security options
PayloadContains log of unsecured payload prior to transmission
ResponseFor synchronous requests or asynchronous receipts verified with verify_receipt, contains MDN receipt, if sent. For asynchronous requests, contains server acknowledgement.
ErrorsA separate file with a .err extension is written when an error is encountered.
AllAll of the above

MDNDisposition:   Returns the Disposition header of the MDN.

This setting returns the Disposition header value from the MDN.

MessageHeaders:   Returns the headers of the message.

This setting returns the headers of the generated message when IncludeHeaders is False and PostToFile is set. It should not be used in any other cases.

NormalizeMIC:   Whether to normalize line endings before calculating the MIC.

This setting determines whether to normalize line endings before signature verification.

In most cases the signature is verified by calculating a Message Integrity Check (MIC) over the exact data that is received. In some cases other software such as Mendelson AS2 may calculate signatures over a version of the data with normalized line endings. During processing attempts to verify a signature that was created in this manner may lead to one of the following errors:

  • Unable to verify content integrity: Message digest mismatch in signature.
  • The receipt signature could not be verified: Message digest mismatch in signature.

If one of the errors above is encountered and the received data is expected to be otherwise correct setting this setting to True may resolve the issue by normalizing line endings before verifying the signature.

Note: This should only be set to True if there is a specific reason to do so.

OAEPMGF1HashAlgorithm:   The MGF1 hash algorithm used when encrypting a key.

When use_oaep is True, this algorithm specifies the MGF1 hash algorithm used for the encryption key by RSA OAEP. Possible values are:

  • "SHA1"
  • "SHA224"
  • "SHA256" (default)
  • "SHA384"
  • "SHA512"

Note: An empty string value indicates that the algorithm specified by OAEPRSAHashAlgorithm is used as the RSA hash algorithm as well.

OAEPParams:   The hex encoded OAEP parameters to be used when encrypting a key.

This setting is optional and should only be specified if OAEP parameters need to be explicitly set. The value specified should be a hex string. By default this setting is unspecified.

OAEPRSAHashAlgorithm:   The RSA hash algorithm used when encrypting a key.

When use_oaep is True, this algorithm specifies the RSA hash algorithm used for the encryption key. This may differ from the hash algorithm used to sign the AS4 message content. Possible values are:

  • "SHA1"
  • "SHA224"
  • "SHA256" (default)
  • "SHA384"
  • "SHA512"
Password:   A password if authentication is to be used.

If AuthScheme is set to Basic, the User and Password are Base64 encoded and the result is put in the Authorization configuration setting in the form "Basic [encoded-user-password]".

If AuthScheme is set to Digest, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.

The User and Password properties must be set only after the url property is set. When the url property is set, for security reasons, User and Password are immediately cleared.

PostToFile:   Creates the message on disk.

This setting allows for the message to be created on disk without actually being sent. This is useful in certain situations to prepare the message where it is sent by a different transport mechanism at a later time. This should be set to a relative or absolute file path including the filename. When this is set the class will immediately start processing the message and writing to the specified file.

RequiredSignatureAlgorithms:   Specifies a list of acceptable signature algorithms.

This setting specifies a comma separated list of allowed signature algorithms used in messages verified by the class. By default the setting is empty and any signature algorithm is supported. To restrict the algorithms to one or more values set this setting to a comma separated list. For instance sha1,sha256.

User:   A user name if authentication is to be used.

If AuthScheme is set to Basic, the User and Password are Base64 encoded and the result is put in the Authorization configuration setting in the form "Basic [encoded-user-password]".

If AuthScheme is set to Digest, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.

The User and Password properties must be set only after the url property is set. When the url property is set, for security reasons, User and Password are immediately cleared.

HTTP Config Settings

AcceptEncoding:   Used to tell the server which types of content encodings the client supports.

When AllowHTTPCompression is True, the class adds an Accept-Encoding header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the Accept-Encoding header. Note: The class only supports gzip and deflate decompression algorithms.

AllowHTTPCompression:   This property enables HTTP compression for receiving data.

This configuration setting enables HTTP compression for receiving data. When set to True (default), the class will accept compressed data. It then will uncompress the data it has received. The class will handle data compressed by both gzip and deflate compression algorithms.

When True, the class adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".

The default value is True.

AllowHTTPFallback:   Whether HTTP/2 connections are permitted to fallback to HTTP/1.1.

This configuration setting controls whether HTTP/2 connections are permitted to fall back to HTTP/1.1 when the server does not support HTTP/2. This setting is applicable only when http_version is set to "2.0".

If set to True (default), the class will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the class fails with an error if the server does not support HTTP/2.

The default value is True.

Append:   Whether to append data to LocalFile.

This configuration setting determines whether data will be appended when writing to local_file. When set to True, downloaded data will be appended to local_file. This may be used in conjunction with range to resume a failed download. This is applicable only when local_file is set. The default value is False.

Authorization:   The Authorization string to be sent to the server.

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The auth_scheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time user and password are set, they are Base64 encoded, and the result is put in the authorization property in the form "Basic [encoded-user-password]".

BytesTransferred:   Contains the number of bytes transferred in the response data.

This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the on_transfer event, by BytesTransferred.

ChunkSize:   Specifies the chunk size in bytes when using chunked encoding.

This is applicable only when UseChunkedEncoding is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

CompressHTTPRequest:   Set to true to compress the body of a PUT or POST request.

If set to True, the body of a PUT or POST request will be compressed into gzip format before sending the request. The "Content-Encoding" header is also added to the outgoing request.

The default value is False.

EncodeURL:   If set to True the URL will be encoded by the class.

If set to True, the URL passed to the class will be URL encoded. The default value is False.

FollowRedirects:   Determines what happens when the server issues a redirect.

This option determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new url for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new url is retrieved automatically only if the URL Scheme is the same; otherwise, the class fails with an error.

Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, user and password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A on_redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the on_redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the class fails with an error instead.

Following are the valid options:

  • 0 - Never
  • 1 - Always
  • 2 - Same Scheme

GetOn302Redirect:   If set to True the class will perform a GET on the new location.

The default value is False. If set to True, the class will perform a GET on the new location. Otherwise, it will use the same HTTP method again.

HTTP2HeadersWithoutIndexing:   HTTP2 headers that should not update the dynamic header table with incremental indexing.

HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically, these headers are inserted into the table through incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

HTTPVersion:   The version of HTTP used by the class.

This property specifies the HTTP version used by the class. Possible values are as follows:

  • "1.0"
  • "1.1" (default)
  • "2.0"
  • "3.0"

When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.

HTTP/2 Notes

When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2, the class will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.

HTTP/3 Notes

HTTP/3 is supported only in .NET and Java.

When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.

IfModifiedSince:   A date determining the maximum age of the desired document.

If this setting contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example: Sat, 29 Oct 2017 19:43:31 GMT.

KeepAlive:   Determines whether the HTTP connection is closed after completion of the request.

If True, the component will not send the Connection: Close header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. Note: Not all servers support persistent connections. If False, the connection will be closed immediately after the server response is received.

The default value for KeepAlive is False.

KerberosSPN:   The Service Principal Name for the Kerberos Domain Controller.

If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

LogLevel:   The level of detail that is logged.

This configuration setting controls the level of detail that is logged through the on_log event. 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).

MaxRedirectAttempts:   Limits the number of redirects that are followed in a request.

When follow_redirects is set to any value other than frNever, the class will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

NegotiatedHTTPVersion:   The negotiated HTTP version.

This configuration setting may be queried after the request is complete to indicate the HTTP version used. When http_version is set to "2.0" (if the server does not support "2.0"), then the class will fall back to using "1.1" automatically. This setting will indicate which version was used.

OtherHeaders:   Other headers as determined by the user (optional).

This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.

This configuration setting is useful for extending the functionality of the class beyond what is provided.

ProxyAuthorization:   The authorization string to be sent to the proxy server.

This is similar to the Authorization configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If proxy_user and proxy_password are specified, this value is calculated using the algorithm specified by proxy_auth_scheme.

ProxyAuthScheme:   The authorization scheme to be used for the proxy.

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyPassword:   A password if authentication is to be used for the proxy.

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyPort:   Port for the proxy server (default 80).

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyServer:   Name or IP address of a proxy server (optional).

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyUser:   A user name if authentication is to be used for the proxy.

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

SentHeaders:   The full set of headers as sent by the client.

This configuration setting returns the complete set of raw headers as sent by the client.

StatusCode:   The status code of the last response from the server.

This configuration setting contains the result code of the last response from the server.

StatusLine:   The first line of the last response from the server.

This setting contains the first line of the last response from the server. The format of the line will be [HTTP version] [Result Code] [Description].

TransferredData:   The contents of the last response from the server.

This configuration setting contains the contents of the last response from the server.

TransferredDataLimit:   The maximum number of incoming bytes to be stored by the class.

If TransferredDataLimit is set to 0 (default), no limits are imposed. Otherwise, this reflects the maximum number of incoming bytes that can be stored by the class.

TransferredHeaders:   The full set of headers as received from the server.

This configuration setting returns the complete set of raw headers as received from the server.

TransferredRequest:   The full request as sent by the client.

This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ HTTP http; http.Config("TransferredRequest=on"); http.SetPostData("body", 5); http.Post("http://someserver.com"); printf("%s\r\n", http.Config("TransferredRequest"));

UseChunkedEncoding:   Enables or Disables HTTP chunked encoding for transfers.

If UseChunkedEncoding is set to True, the class will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the class will not use HTTP-chunked encoding. The default value is False.

Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

UseIDNs:   Whether to encode hostnames to internationalized domain names.

This configuration setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True, if a hostname contains non-ASCII characters, it is encoded using Punycode to an IDN (internationalized domain name).

The default value is False and the hostname will always be used exactly as specified. Note: The CodePage setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set CodePage to 65001. In the C++ Edition for Windows, the *W version of the class must be used. For instance, DNSW or HTTPW.

UsePlatformHTTPClient:   Whether or not to use the platform HTTP client.

When using this configuration setting, if True, the component will use the default HTTP client for the platform (URLConnection in Java, WebRequest in .NET, or CFHTTPMessage in Mac/iOS) instead of the internal HTTP implementation. This is important for environments in which direct access to sockets is limited or not allowed (e.g., in the Google AppEngine).

Note: This setting is applicable only to Mac/iOS editions.

UseProxyAutoConfigURL:   Whether to use a Proxy auto-config file when attempting a connection.

This configuration specifies whether the class will attempt to use the Proxy auto-config URL when establishing a connection and proxy_auto_detect is set to True.

When True (default), the class will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.

UserAgent:   Information about the user agent (browser).

This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

TCPClient Config Settings

ConnectionTimeout:   Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect:   Tells the class whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType:   Determines the type of firewall to connect through.

The appropriate values are as follows:

0No firewall (default setting).
1Connect through a tunneling proxy. FirewallPort is set to 80.
2Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger:   When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime:   Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost:   The name of the local host through which connections are initiated or accepted.

The local_host setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the local_host setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the class binds.

This configuration setting must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by local_port after the connection is established.

local_port cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength:   The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an eol string.

If an eol string is found in the input stream before MaxLineLength bytes are received, the on_data_in event is fired with the EOL parameter set to True, and the buffer is reset.

If no eol is found, and MaxLineLength bytes are accumulated in the buffer, the on_data_in event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate:   The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList:   A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive:   Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this configuration setting is set to False.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are as follows:

0 IPv4 only
1 IPv6 only
2 IPv6 with IPv4 fallback

SSL Config Settings

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When ssl_provider 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 event, which will fire each time an SSL packet is sent or received.

Enabling this configuration setting has no effect if ssl_provider 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 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:

-----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 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 is currently not supported. This functionality is instead made available through the 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 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:

-----BEGIN CERTIFICATE-----

-----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 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 is set to Platform include the following: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when ssl_provider is set to Platform include the following:

When TLS 1.3 is negotiated (see SSLEnabledProtocols), only the following cipher suites are supported:

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with 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:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default - Client and Server)
TLS1.1768 (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 use the internal TLS implementation when the ssl_provider is set to Automatic for all editions.

In editions that are designed to run on Windows, ssl_provider 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 and other similar SSL configuration settings are not supported.
  • If 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 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 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 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 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 event.

If set to True, all certificates returned by the server will be present in the Encoded parameter of the on_ssl_server_authentication 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 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: 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: 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: 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: 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: 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: 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:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown certificate authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown certificate authority revocation status.
0x00000800Ignore unknown root revocation status.
0x00008000Allow test root certificate.
0x00004000Trust test root certificate.
0x80000000Ignore 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 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:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

-----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 is set to Internal and 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: 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 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 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

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)

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method that does not complete within timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for User Datagram Protocol (UDP) ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the InBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. 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.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

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 article.

Note: This setting is applicable only on Windows.

Note: Enabling FIPS compliance requires a special license; please contact 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 section.
