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