I should have corrected this when i first saw it.  It was a typo.  Anyone
familiar with what i meant to say would have flagged that down immediately
as an error.  It should have read:

SSH allows for public key *authentication*.  Which actually means that you
need not have a password in order to log in.  You just need to have a a
predefined, shared key between two sites in order for a successful
authentication to occur.

Of course SSL has public keys, because SSH uses the SSL libraries
extensively.

Yes, and you could also configure applications like perl and vi to do the
same.  But why bother and do that at all when SSH is already there.

Real sysadmins with extensive experience in network security know that it
is an ongoing process and not simply a selection of what programs to use.

Your pot-shot at the information i provided not only degraded its value to
those who would like to learn from what i said, it also misleads the
readers as to the viability SSH is as a solution to network security.

Please the next time you poke humor into an otherwise serious topic, think
twice.  This is not a laughing matter.
