Even if it is the longer one, if I'm not mistaken, log2(36^25) ~ 129.
For a birthday attack by a powerful adversary, and where presumably
the attacker can generate numerous keys and possibly somehow
deliberately craft the generated keys in order to get (closer to) a
desired fingerprint, is that really sufficient?
