When I make a ssh connection (5510, pix 7) PuTTY gives a security alert to confirm the pix rsa key fingerprint. Is there a way to see the fingerprint of the pix generated rsa key?

sh cry key mypubkey rsa will show you the public key. The fingerprint should be displayed when you first connect via putty. Did the ssh key recently change?

I would like to know if the fingerprint shown by PuTTY matches the pix public key fingerprint.

I dont know of any way other than to zeroize the rsa key, generate a new key and document the fingerprint when you reconnect.

Yes, the need to document the SSH fingerprints after install have been a bit of a pain for quite some time.
Dont know how popular external links are in this forum, but Didier Stevens seem to have solved this
problem for us, and even provided a Python script for it:
