finding hashes
Well one way is to type them into http://www.securitystats.com/tools/hashcrack.php It's an online cracker for SHA1, NT, LANMAN, MD4 and MD5 hashes. If the hash is in their database, you get the password + format, otherwise you get the format.
Btw, JtR can also auto-detect what type a hash is.
