- Seeking help - how to calculate fingerprints

I often get this too familiar message, and want to know how to calculate
fingerprint. I do a lot of port forwarding, so I believe I have multiple
"localhost" keys that actually come from remote hosts. So I need to decide if
this fingerprint (allegedly "changed") is really changed, or is just due to
another host whose port was forwarded.
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
The fingerprint for the RSA key sent by the remote host is
I tried md5sum on entries for localhost in ssh_known_hosts file, but I fail to
get the same fingerprint that ssh gives me.
I would appreciate a pointer to a command, function or library that will do the
job. If possible I'd like to know one for windows platform (other than cygwin)
and one for unix platform (including cygwin).

If you're port-forwarding ssh itself and using OpenSSH, you can use
HostKeyAlias to store the key with the appropriate name associated with

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
