While SHA-1 has not yet been broken, there are worrying signs. Related
and weakened versions have been broken, SHA-1 itself has been "broken"
by algorithms which are still impractically expensive but much cheaper
than brute force, and it's generally accepted that the full SHA-1 is
just a matter of time. It's premature to start ripping SHA-1 out of
existing code, but if you are writing new code for which security is a
concern, it's best to start using one of the SHA-2 family of hashes.
