RFC 4256 - Generic Message Exchange Authentication for the Secure Shell Protocol (SSH)
12.01.2006
Abstract:
The Secure Shell Protocol (SSH) is a protocol for secure remote login
and other secure network services over an insecure network. This
document describes a general purpose authentication method for the
SSH protocol, suitable for interactive authentications where the
authentication data should be entered via a keyboard (or equivalent
alphanumeric input device). The major goal of this method is to
allow the SSH client to support a whole class of authentication
mechanism(s) without knowing the specifics of the actual
authentication mechanism(s).
