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 Command and CommandReply 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}"); };

The ID of the pre-shared key used for DC request authentication.

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 ExternalCryptoKeySecret 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";

Data Type

String

TLSRevocationCheck Property (SecureBlackbox_SMTPClient Class)

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

Object Oriented Interface

public function getTLSRevocationCheck();
public function setTLSRevocationCheck($value);

Procedural Interface

secureblackbox_smtpclient_get($res, 288 );
secureblackbox_smtpclient_set($res, 288, $value );

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.

This property is not available at design time.

secureblackbox_smtpclient_register_callback($res, 8, array($this, 'fireExternalSign'));

Parameter List

 'operationid'
 'hashalgorithm'
 'pars'
 'data'
 'signeddata'

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(); };
