This script:
http://www.zip.com.au/~cs/scripts/pwcrypt
does it for old style crypt() passwords. There should be equivalent code
for the MD5 stuff. The only thing you've missed is that most of these
things use a salt, kept with the hash, to make sure that if two people
have the same password, their hashes _aren't_ the same.
Anyway, your basic idea is correct: hash the passwords and compare.
