Rebex FTP/SSL for .NET 2020 R2
Released: May 24, 2020
Updates in 2020 R2
Features
- FTP: Added FtpExtensions.ExtendedPassiveMode (enables EPSV if supported by the server).
- FTP: Added FtpSettings.EnableBrokenShutdownWorkaround option (workaround for FTPS servers that don't handle TLS 1.3 close messages properly).
- SSH: Added new properties to SshCipher to make it possible to determine IDs of active ciphers.
- SSH: Added workaround for a weakness in legacy CBC ciphers.
- TLS Core: Enhanced TlsSocket.Timeout property to apply to subsequent Send, SendAsync, Receive and ReceiveAsync methods even when TLS is already active.
- TLS Core: Improved and unified behavior of the TlsSocket Shutdown/ShutdownAsync methods when negotiation has not been started.
- TLS Core: Improved TLS exception reporting.
- TLS Core: Logging improvements.
- TLS Core: Optimizations in TLS 1.3 internals.
- TLS Core: Support for the TLS 1.3 record with empty application data payload and random padding.
- TLS Core: Unified TlsSocket.Cipher property behavior across TLS versions.
- TLS: Added TlsServerSocket class. Provides server-side TLS 1.3, 1.2, 1.1 and 1.0 support.
- Cryptography: Added ContentInfo.ToStream() method.
- Cryptography: Enhanced Certificate.LoadDerWithKey to support RSASSA-PSS and RSAES-OAEP for RSA keys.
- Cryptography: Improved AsymmetricKeyAlgorithm to support RSASSA-PSS and RSAES-OAEP with keys loaded via ImportKey method.
- Cryptography: Optimized Certificate and CertificateChain class to only consume native resources when needed.
- Cryptography: Optimized CNG handles cleanup.
Fixes
- TLS Core: Fixed availability of TLS 1.3 session ticket when the receive side of the connection has already been closed.
- TLS Core: Fixed behavior of server-side DoNotCacheSessions option (which previously led to connection failures).
- TLS Core: Fixed some cases of missing AggregateException unwrapping.
- TLS: Fixed TlsClientSocket.EndConnect method.
- Cryptography: Fixed AsymmetricKeyAlgorithm.GenerateDiffieHellmanParameters slowness (only affected the previous release).
