Adds new binaries for .NET Core 3.1 and .NET 5.0 Preview 6, on Windows, Linux and macOS.
Features
- All: Added binaries targeting Microsoft .NET Standard 2.1.
- File Server: Added support for anonymous authentication.
- File Server: Changed SSH cipher info logging style (unified with client-side SSH).
- SSH Shell: When TerminalOptions.LocalEcho is enabled, echo opcode is requested on SSH channel.
- SSH: Enhanced legacy group exchange autodetection.
- TLS Core: Added TlsSocket.ApplicationProtocol property to make it possible to determine protocol negotiated using ALPN extension.
- TLS Core: Now always prefers RSA/SHA-2 for client certificate authentication in TLS 1.2.
- TLS Core: Disabled ciphers based on AES/CBC and SHA-2 in legacy versions of TLS (they are only specified by TLS 1.2).
- TLS Core: Improved error message when server certificate is rejected in TLS 1.3.
- TLS Core: Improved error messages in TLS 1.3.
- TLS Core: Logging improvements.
- TLS Core: No longer sending 'internal error' alert to remote end on timeout.
- TLS Core: Optimized TLS 1.3 internals.
- TLS Core: TLS 1.3 initiates key update properly (before the AEAD limits are reached).
- TLS Core: Unified behavior of the Receive and ReceiveAsync methods across TLS versions.
- TLS: Added DisposeAsync method to TlsSocket.
- TLS: Added server-side support for Application-Layer Protocol Negotiation (ALPN) extension (RFC 7301).
- TLS: Added TlsParameters.CertificateChainMode property.
- TLS: Added TlsStream class. Supports TLS 1.0-1.3 via Stream-based API.
- TLS: An error is reported when trying to use one of deprecated methods via TlsServerSocket.
- Cryptography: Memory usage optimizations in CNG layer.
- Cryptography: On Microsoft Windows 10 and Microsoft Windows Server 2016 or higher, Microsoft CNG API is used for classic Diffie-Hellman calculations instead of legacy Microsoft CryptoAPI.
- Cryptography: Optimized disposing of temporary keys in Certificate class.
