twisted.conch.ssh.transport

module documentation
(source)

The lowest level SSH protocol. This handles the key negotiation, the encryption and the compression. The transport layer is described in RFC 4253.

Maintainer: Paul Swartz

Class SSHCiphers SSHCiphers represents all the encryption operations that need to occur to encrypt and authenticate the SSH connection.
Class SSHClientTransport SSHClientTransport implements the client side of the SSH protocol.
Class SSHServerTransport SSHServerTransport implements the server side of the SSH protocol.
Class SSHTransportBase Protocol supporting basic SSH functionality: sending/receiving packets and message dispatch. To connect to or run a server, you must use SSHClientTransport or SSHServerTransport.
