Search for passwords on IT Security and you will find tons of advice on how to store passwords, and how not to. Your scheme is not a good method for hashing passwords: it is a fast hash, it lacks any salt, and it unnecessarily limits the password length. People have studied this at great length: before trying to re-invent the wheel, I suggest you read up ...

I think what you are looking for is a Password-Based Key Derivation Function (PBKDF).
You can take a moderately strong password, like 12-14 random letters and numbers (no dictionary words though!), and throw it into the PBKDF function together with some other parameters, e.g. salt, number of iterations and the desired key length.
After that you have a ...

What you are looking for is a Pseudo Random Function that should be indistinguishable from uniform, even if the key material that is passed to it is not. One potential problem with your scheme is that the AES key schedule is not particularly good at extracting the entropy from keys that are not selected (pseudo-)randomly, such as passwords and pass-phrases. ...
