What about a fascist passwd program which refers to a dictionary and
rejects "easy" passwords? Does such an animal exist?

I think this one comes under the heading of "brute force attack" - just
with alphanumerics (a-z,A-Z,0-9) you're looking at needing 62^8 entries
for a complete set of 8 character passwords. It's probably faster to try
and decrypt the passwd file entry directly.
