I think it's a bad idea to use hashing and salting for password storage.

Cryptographers recommend using an *adaptive* hash such as PBKDF2, bcrypt 
or scrypt today.


MD5 is WAY past broken for password storage. Not because the hash is bad 
- but any hash is bad - because they are fast. You need to store 
passwords in a way that is slow.
