Salted Password Hashing

Here are some examples of poor wacky hash functions I've seen suggested in forums on the internet.

• md5(sha1(password))
• md5(md5(salt) + md5(password))
• sha1(sha1(password))
• sha1(str_rot13(password + salt))
• md5(sha1(md5(md5(password) + sha1(password)) + md5(password)))
