s. In fact it's insecure on so many levels that I don't know where to start... A hash function and a fixed salt are always the wrong way to handle passwords. You must use a non-deterministic key stretching and key derivation function with a salt from a CPRNG. For example PBKDF2 (usually used with HMAC as PRF), bcrypt or scrypt are well studied and tune-able KDFs. You must also use a constant timing comparison function. You don't have to do all the hard stuff on your own. I highly recommend `passlib` to handle your passwords. It has a good API and is secure.
