2. Bindings to SSHv2 channels
SSHv2 [RFC4251] provides both, a secure channel and material (the
SSHv2 "session ID") that is suitable for use as channel binding
identifiers [I-D.williams-on-channel-bindings].
Thus it is RECOMMENDED that the SSHv2 "session ID" be used as the
channel bindings for SSHv2.
