Appendix F: SSH-2 names specified for PuTTY
There are various parts of the SSH-2 protocol where things are specified using a textual name. Names ending in @putty.projects.tartarus.org
are reserved for allocation by the PuTTY team. Allocated names are documented here.
F.1 Connection protocol channel request names
These names can be sent in a SSH_MSG_CHANNEL_REQUEST
message.
simple@putty.projects.tartarus.org
- This is sent by a client to announce that it will not have more than one channel open at a time in the current connection (that one being the one the request is sent on). The intention is that the server, knowing this, can set the window on that one channel to something very large, and leave flow control to TCP. There is no message-specific data.
winadj@putty.projects.tartarus.org
- PuTTY sends this request along with some
SSH_MSG_CHANNEL_WINDOW_ADJUST
messages as part of its window-size tuning. It can be sent on any type of channel. There is no message-specific data. Servers MUST treat it as an unrecognised request and respond withSSH_MSG_CHANNEL_FAILURE
.(Some SSH servers get confused by this message, so there is a bug-compatibility mode for disabling it. See section 4.27.5.)
F.2 Key exchange method names
rsa-sha1-draft-00@putty.projects.tartarus.org
rsa-sha256-draft-00@putty.projects.tartarus.org
rsa1024-sha1-draft-01@putty.projects.tartarus.org
rsa1024-sha256-draft-01@putty.projects.tartarus.org
rsa2048-sha256-draft-01@putty.projects.tartarus.org
rsa1024-sha1-draft-02@putty.projects.tartarus.org
rsa2048-sha512-draft-02@putty.projects.tartarus.org
rsa1024-sha1-draft-03@putty.projects.tartarus.org
rsa2048-sha256-draft-03@putty.projects.tartarus.org
rsa1024-sha1-draft-04@putty.projects.tartarus.org
rsa2048-sha256-draft-04@putty.projects.tartarus.org
- These appeared in various drafts of what eventually became RFC 4432. They have been superseded by
rsa1024-sha1
andrsa2048-sha256
.
F.3 Encryption algorithm names
arcfour128-draft-00@putty.projects.tartarus.org
arcfour256-draft-00@putty.projects.tartarus.org
- These were used in drafts of what eventually became RFC 4345. They have been superseded by
