- Description: ========================================================
- PKCS#5 password-based key derivation function 2 (PBKDF2)
- ========================================================
-
- This is a backport of ``hashlib.pbkdf2_hmac`` for Python 2.6 to 2.7. The
- implementation comes with a pure Python implementation and a C module that
- depends on OpenSSL. The C code does *not* wrap ``PKCS5_PBKDF2_HMAC`` as
- its implementation is suboptimal.
-
-
- Usage
- =====
-
- ::
-
- >>> from backports.pbkdf2 import pbkdf2_hmac, compare_digest
- >>> dkey = pbkdf2_hmac('sha1', passwordbytes, saltbytes, iterations=100000)
- >>> compare_digest(dkey, originalkey)
- True
-
-
- pbkdf2_hmac(hash_name, password, salt, iterations, dklen=None)
-
- hash_name
- name of the digest algorithm as string
-
- password
- password as bytes, bytearray or bytes-like object (*)
-
- salt
- salt as bytes, bytearray or bytes-like object (*). The salt should be
- generated with a CPRNG like ``os.urandom()``. You should **never** use
- ``random.random()``. About 16 bytes seem to be a good choice.
-
- iterations
- number of rounds, 100,000 rounds of SHA-1 take about 30ms on a modern
- CPU.
-
- dklen
- length of the derived key (defaults to digest_size)
-
- returns
- derived key as bytes
-
- (*) bytearray and bytes-like objects are not supported on Python 2.6
