Version Description
Version 12.1.1
(25 March, 2024)
  • Add support for ECDSA server certificates in TLS 1.2 (previously only in TLS 1.3).
Version 12.1.0
(18 March, 2024)
  • Please note that this release requires .NET framework 4.7.2 or .NET Standard 2.0.
  • Replace .NET CORE support with support for .NET standard 2.0.
  • Add support for ECDSA server certificates in TLS.
  • Add support for diffie-hellman-group-15-sha512 to diffie-hellman-group-18-sha512 in SSH key exchange.
  • Fix TLS session resumption, which wasn't working for TLS 1.2 and lower.
  • Fix bug in reading the new OpenSSH format for private keys when no passphrase is used.
Version 12.0.0
(16 June, 2023)
  • Support for TLS 1.3.

Version 11.1.1
(26 September, 2022)
  • SSH/SFTP bug fix. If there is an RSA-SHA2-256/512 negotiation with the server, the server sends a list of server-sig-algs that are supported. The client falls over with an Unknown HostKeyAlgorithm error if the server sends an unrecognised algorithm, which is a bug. All it needs to do is skip the unknown algorithm as it parses the list.
