Introducing Rebex SMTP

This is the first release of stand-alone Rebex SMTP library for .NET.

Rebex SMTP library has been available since 2006 as part of Rebex Mail, a package of multiple e-mail libraries.

Detailed list of changes:

  • SSH: Fixed less common variants of multi-factor authentication.
  • SSH: Fixed SshSession.Authenticate(userName, password, privateKey) method that crashed when privateKey was null (since version 7.0).
  • Cryptography: Added ValidationOptions.​DisableCertificateDownloads option (only supported on .NET 5 and higher).
  • Cryptography: Fixed detection of support for ECDH with brainpool curves on iOS.
  • Cryptography: Fixed padding issues in AsymmetricKeyAlgorithm.​GetKeyMaterialDeriver (did not affect Rebex libraries).
  • Cryptography: Fixed wrong RSA public key format when saving private keys in new OpenSSH format.
  • Cryptography: Improved handling of wrong (negative) serial numbers in X.509 certificates.
