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