Syntax

class secureblackbox.SMTPClient

Remarks

Use this component to send e-mails from your application.

You can connect to an SMTP server using either username/password or with an access token. // Connect using username/password SMTPClient client = new SMTPClient(); client.Username = "user"; client.Password = "password"; client.Connect("mail.domain.com", 465); client.SendFile("path\\message.eml"); client.Disconnect(); // Connect using an access token (note that the username should be the same as the one used to obtain the access token) SMTPClient client = new SMTPClient(); client.Username = "user"; client.AccessToken = access_token; client.Connect("smtp.gmail.com", 587); client.SendBytes(buffer); client.Disconnect(); // To send messages without authentication, switch off ForceLogin config property SMTPClient client = new SMTPClient(); client.Config("ForceLogin=false"); client.Connect("smtp.myisp.net", 25); client.SendBytes(buffer); client.Disconnect();

Use on_command and on_command_reply events to get a session log. SMTPClient client = new SMTPClient(); client.OnCommand += delegate (Object sender, SMTPClientCommandEventArgs e) { Console.WriteLine($"C: {e.Cmd}"); }; client.OnCommandReply += delegate (Object sender, SMTPClientCommandReplyEventArgs e) { Console.WriteLine($"S: {e.Reply}"); };

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use external_crypto_key_secret to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

def set_tls_revocation_check(value: int) -> None: ...

tls_revocation_check = property(get_tls_revocation_check, set_tls_revocation_check)

Default Value

1

Remarks

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

Note: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

Note: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

Returns the raw certificate data in DER format.

Syntax

def get_trusted_cert_bytes(trusted_cert_index: int) -> bytes: ...

Remarks

Returns the raw certificate data in DER format.

The trusted_cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the trusted_cert_count property.

This property is read-only.

trusted_cert_handle Property

Allows to get or set a 'handle', a unique identifier of the underlying property object.

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.

connect Method

ErrorCode contains an error code, and ErrorMessage contains an error message.

ServerReply provides the error info reported by the server. This info depends on the transport protocol and on the authentication method.

Set the TryAgain parameter to true if the class should try to authenticate again. If the parameter remains false, the authentication will fail with an exception.

on_auth_start Event

Fires when the authentication is about to be started.

Syntax

class SMTPClientAuthStartEventParams(object):
  @property
  def usable_auths() -> str: ...

# In class SMTPClient:
@property
def on_auth_start() -> Callable[[SMTPClientAuthStartEventParams], None]: ...
@on_auth_start.setter
def on_auth_start(event_hook: Callable[[SMTPClientAuthStartEventParams], None]) -> None: ...

Remarks

The class fires this event when it has established the TCP connection and is ready to proceed to the user authentication step.

The UsableAuths parameter contains a comma-separated list of the authentication methods supported by both, the client and the server.

In this event handler it's possible to update the method list in the Authentications config property according to the provided list of usable methods. The full list of the authentication methods supported by the server is available in ServerInfo.SupportedAuths.

on_auth_succeeded Event

Fires when the authentication has succeeded.

Syntax

class SMTPClientAuthSucceededEventParams(object):
  @property
  def auth() -> str: ...

# In class SMTPClient:
@property
def on_auth_succeeded() -> Callable[[SMTPClientAuthSucceededEventParams], None]: ...
@on_auth_succeeded.setter
def on_auth_succeeded(event_hook: Callable[[SMTPClientAuthSucceededEventParams], None]) -> None: ...

Remarks

The class fires this event when it has succeeded to authenticate to the server. Auth reports the authentication method that has succeeded.

on_command Event

Reports a command sent to the server.

Syntax

class SMTPClientCommandEventParams(object):
  @property
  def cmd() -> str: ...

# In class SMTPClient:
@property
def on_command() -> Callable[[SMTPClientCommandEventParams], None]: ...
@on_command.setter

on_error Event

Provides information about errors during SMTP operations.

Syntax

class SMTPClientErrorEventParams(object):
  @property
  def error_code() -> int: ...

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

# In class SMTPClient:
@property
def on_error() -> Callable[[SMTPClientErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[SMTPClientErrorEventParams], None]) -> None: ...

Remarks

This event is fired in case of exceptional conditions occured during SMTP operations.

ErrorCode contains an error code and Description contains a textual description of the error.

on_external_sign Event

Handles remote or external signing initiated by the SignExternal method or other source.

Syntax

class SMTPClientExternalSignEventParams(object):
  @property
  def operation_id() -> str: ...

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

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

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

  @property
  def signed_data() -> str: ...
  @signed_data.setter
  def signed_data(value) -> None: ...

# In class SMTPClient:
@property
def on_external_sign() -> Callable[[SMTPClientExternalSignEventParams], None]: ...
@on_external_sign.setter
def on_external_sign(event_hook: Callable[[SMTPClientExternalSignEventParams], None]) -> None: ...

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the class via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

on_notification Event

This event notifies the application about an underlying control flow event.

Syntax

class SMTPClientNotificationEventParams(object):
  @property
  def event_id() -> str: ...

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

# In class SMTPClient:
@property
def on_notification() -> Callable[[SMTPClientNotificationEventParams], None]: ...
@on_notification.setter
def on_notification(event_hook: Callable[[SMTPClientNotificationEventParams], None]) -> None: ...

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.

This class can fire this event with the following EventID values:

on_progress Event

Reports the progress of the data transfer operation.

Syntax

class SMTPClientProgressEventParams(object):
  @property
  def total() -> int: ...

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

  @property
  def cancel() -> bool: ...
  @cancel.setter
  def cancel(value) -> None: ...

# In class SMTPClient:
@property
def on_progress() -> Callable[[SMTPClientProgressEventParams], None]: ...
@on_progress.setter
def on_progress(event_hook: Callable[[SMTPClientProgressEventParams], None]) -> None: ...

Remarks

The class fires this event repeatedly to report the progress of the data transfer operation.

on_tls_cert_needed Event

Fires when a remote TLS party requests a client certificate.

Syntax

class SMTPClientTLSCertNeededEventParams(object):
  @property
  def host() -> str: ...

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

# In class SMTPClient:
@property
def on_tls_cert_needed() -> Callable[[SMTPClientTLSCertNeededEventParams], None]: ...
@on_tls_cert_needed.setter
def on_tls_cert_needed(event_hook: Callable[[SMTPClientTLSCertNeededEventParams], None]) -> None: ...

Remarks

This event fires to notify the implementation that a remote TLS server has requested a client certificate. The Host parameter identifies the host that makes a request, and the CANames parameter (optional, according to the TLS spec) advises on the accepted issuing CAs.

Use the tls_client_chain property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire.

This event is preceded by the on_tls_handshake event for the given host and, if the certificate was accepted, succeeded by the on_tls_established event.

on_tls_cert_validate Event

This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.

Syntax

class SMTPClientTLSCertValidateEventParams(object):
  @property
  def server_host() -> str: ...

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

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class SMTPClient:
@property
def on_tls_cert_validate() -> Callable[[SMTPClientTLSCertValidateEventParams], None]: ...
@on_tls_cert_validate.setter
def on_tls_cert_validate(event_hook: Callable[[SMTPClientTLSCertValidateEventParams], None]) -> None: ...

Remarks

This event is fired during a TLS handshake. Use the tls_server_chain property to access the certificate chain. In general, classes may contact a number of TLS endpoints during their work, depending on their configuration.

Accept is assigned in accordance with the outcome of the internal validation check performed by the class, and can be adjusted if needed.

on_tls_established Event

Fires when a TLS handshake with Host successfully completes.

Syntax

class SMTPClientTLSEstablishedEventParams(object):
  @property
  def host() -> str: ...

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

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

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

  @property
  def abort() -> bool: ...
  @abort.setter
  def abort(value) -> None: ...

# In class SMTPClient:
@property
def on_tls_established() -> Callable[[SMTPClientTLSEstablishedEventParams], None]: ...
@on_tls_established.setter
def on_tls_established(event_hook: Callable[[SMTPClientTLSEstablishedEventParams], None]) -> None: ...

Remarks

The class uses this event to notify the application about a successful completion of a TLS handshake.

The Version, Ciphersuite, and ConnectionId parameters indicate the security parameters of the new connection. Use the Abort parameter if you need to terminate the connection at this stage.

on_tls_handshake Event

Fires when a new TLS handshake is initiated, before the handshake commences.

Syntax

class SMTPClientTLSHandshakeEventParams(object):
  @property
  def host() -> str: ...

  @property
  def abort() -> bool: ...
  @abort.setter
  def abort(value) -> None: ...

# In class SMTPClient:
@property
def on_tls_handshake() -> Callable[[SMTPClientTLSHandshakeEventParams], None]: ...
@on_tls_handshake.setter
def on_tls_handshake(event_hook: Callable[[SMTPClientTLSHandshakeEventParams], None]) -> None: ...

Remarks

The class uses this event to notify the application about the start of a new TLS handshake to Host. If the handshake is successful, this event will be followed by the on_tls_established event. If the server chooses to request a client certificate, the on_tls_cert_needed event will also be fired.

on_tls_psk Event

Notifies the application about the PSK key exchange.

Syntax

class SMTPClientTLSPSKEventParams(object):
  @property
  def host() -> str: ...

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

# In class SMTPClient:
@property
def on_tls_psk() -> Callable[[SMTPClientTLSPSKEventParams], None]: ...
@on_tls_psk.setter
def on_tls_psk(event_hook: Callable[[SMTPClientTLSPSKEventParams], None]) -> None: ...

Remarks

The class fires this event to notify the application about the beginning of TLS-PSK key exchange with Host. The Hint parameter may be used by the server to identify the key or service to use. Use the PreSharedKey field of tls_settings to provide the pre-shared key to the component.

on_tls_shutdown Event

Reports the graceful closure of a TLS connection.

Syntax

class SMTPClientTLSShutdownEventParams(object):
  @property
  def host() -> str: ...

# In class SMTPClient:
@property
def on_tls_shutdown() -> Callable[[SMTPClientTLSShutdownEventParams], None]: ...
@on_tls_shutdown.setter
def on_tls_shutdown(event_hook: Callable[[SMTPClientTLSShutdownEventParams], None]) -> None: ...

Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

SMTPClient 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.
