It implements PKCS#5's password based key derivation function 2 with HMAC as pseudo-random function. It supports any digest that is supported by OpenSSL, e.g. SHA-1, SHA-256 and SHA-512. It's a low level inteface that takes the digest as unicode name, password and salt as bytes/buffer, keylen and rounds as int. I'd like to add the feature to Python 3.4. Now I'm looking for a good place to put it and some high level functions. In the future I like to add scrypt and bcrypt key stretching and key derivation functions, too. What's a good place for them?? [SNIP] * add PBKDF2 to hashlib * make hashlib a package and add PBKDF2 to a new hashlib.kdf module * make hashlib a package and add PBKDF2 to a new hashlib.pbkdf2 module One of these three depending on how bug the new API is (smaller the less need to add new modules).

+1 to hashlib from me (especially since we used that as the best available home for compare_digest).

Cheers, Nick.
