 271 IETF secsh working group and is specified in several RFCs and drafts.
 272 It is composed of three layered components:
 273
 274 The transport layer provides algorithm negotiation and a key exchange.
 275 The key exchange includes server authentication and results in a
 276 cryptographically secured connection: it provides integrity, confidentiality
 277 and optional compression.
 278
 279 The user authentication layer uses the established connection and relies on
 280 the services provided by the transport layer.  It provides several mechanisms
 281 for user authentication.  These include traditional password authentication
 282 as well as public-key or host-based authentication mechanisms.
 283
 284 The connection layer multiplexes many different concurrent channels over the
 285 authenticated connection and allows tunneling of login sessions and
 286 TCP-forwarding.  It provides a flow control service for these channels.
 287 Additionally, various channel-specific options can be negotiated.")
