 203     "The SSH2 protocol implemented in OpenSSH is standardised by the
 204 IETF secsh working group and is specified in several RFCs and drafts.
 205 It is composed of three layered components:
 206
 207 The transport layer provides algorithm negotiation and a key exchange.
 208 The key exchange includes server authentication and results in a
 209 cryptographically secured connection: it provides integrity, confidentiality
 210 and optional compression.
 211
 212 The user authentication layer uses the established connection and relies on
 213 the services provided by the transport layer.  It provides several mechanisms
 214 for user authentication.  These include traditional password authentication
 215 as well as public-key or host-based authentication mechanisms.
 216
 217 The connection layer multiplexes many different concurrent channels over the
 218 authenticated connection and allows tunneling of login sessions and
 219 TCP-forwarding.  It provides a flow control service for these channels.
 220 Additionally, various channel-specific options can be negotiated.")
