v0.1.66

• Added support for RFC 8308 extension negotiation and server-sig-algs extension
  • This support is enabled by default, but can be controlled via the enable_server_sig_algs config option (or jsch.enable_server_sig_algs system property)
  • When enabled and a server-sig-algs message is received from the server, the algorithms included by the server and also present in the PubkeyAcceptedKeyTypes config option will be attempted first when using publickey authentication
  • Additionally if the server is detected as OpenSSH version 7.4, the rsa-sha2-256 & rsa-sha2-512 algorithms will be added to the received server-sig-algs as a workaround for OpenSSH bug 2680
• Added support for various algorithms supported by Tectia (ssh.com):

• Added support for SHA224 to FingerprintHash
• Fixing #52
• Deprecate void setFilenameEncoding(String encoding) in favor of void setFilenameEncoding(Charset encoding) in ChannelSftp
• Added support for rsa-sha2-256 & rsa-rsa2-512 algorithms to ChannelAgentForwarding
• Address #65 by adding ssh-agent support derived from jsch-agent-proxy
  • See examples/JSchWithAgentProxy.java for simple example
  • ssh-agent support requires either Java 16's JEP 380 or the addition of junixsocket to classpath
  • Pageant support is untested & requires the addition of JNA to classpath
• Added support for the following algorithms with older Java releases by using Bouncy Castle:
  • ssh-ed25519
  • ssh-ed448
  • curve25519-sha256
