 215     "The SSH2 protocol implemented in OpenSSH is standardised by the
 216 IETF secsh working group and is specified in several RFCs and drafts.
 217 It is composed of three layered components:
 218
 219 The transport layer provides algorithm negotiation and a key exchange.
 220 The key exchange includes server authentication and results in a
 221 cryptographically secured connection: it provides integrity, confidentiality
 222 and optional compression.
 223
 224 The user authentication layer uses the established connection and relies on
 225 the services provided by the transport layer.  It provides several mechanisms
 226 for user authentication.  These include traditional password authentication
 227 as well as public-key or host-based authentication mechanisms.
 228
 229 The connection layer multiplexes many different concurrent channels over the
 230 authenticated connection and allows tunneling of login sessions and
 231 TCP-forwarding.  It provides a flow control service for these channels.
 232 Additionally, various channel-specific options can be negotiated.")
