        "description": "========================================================\nPKCS#5 password-based key derivation function 2 (PBKDF2)\n========================================================\n\nThis is a backport of ``hashlib.pbkdf2_hmac`` for Python 2.6 to 2.7. The\nimplementation comes with a pure Python implementation and a C module that\ndepends on OpenSSL. The C code does *not* wrap ``PKCS5_PBKDF2_HMAC`` as\nits implementation is suboptimal.\n\n\nUsage\n=====\n\n::\n\n  >>> from backports.pbkdf2 import pbkdf2_hmac, compare_digest\n  >>> dkey = pbkdf2_hmac('sha1', passwordbytes, saltbytes, iterations=100000)\n  >>> compare_digest(dkey, originalkey)\n  True\n\n\npbkdf2_hmac(hash_name, password, salt, iterations, dklen=None)\n\n  hash_name\n    name of the digest algorithm as string\n\n  password\n    password as bytes, bytearray or bytes-like object (*)\n\n  salt\n    salt as bytes, bytearray or bytes-like object (*). The salt should be\n    generated with a CPRNG like ``os.urandom()``. You should **never** use\n    ``random.random()``. About 16 bytes seem to be a good choice.\n\n  iterations\n    number of rounds, 100,000 rounds of SHA-1 take about 30ms on a modern\n    CPU.\n\n  dklen\n    length of the derived key (defaults to digest_size)\n\n  returns\n    derived key as bytes\n\n  (*) bytearray and bytes-like objects are not supported on Python 2.6\n\n\nBenchmarks\n==========\n\n====================   =====   =====   =====   ======\npassword length           10     100     500     1000\n====================   =====   =====   =====   ======\nbackports.pbkdf2 C     0.314   0.321   0.310    0.310\nbackports.pbkdf2 Py    0.838   0.847   0.853    0.913\npbkdf2_ctypes 0.99.3   0.554   0.663   0.954    1.344\npbkdf2 1.3             5.235   5.746   6.155    6.450\nDjango pbkdf2 1.5.4    1.976   2.430   2.676    3.078\nPyCrypto 2.6.1         6.903   9.062   9.518   10.274\n====================   =====   =====   =====   ======\n\n  algorithm\n    sha1\n  rounds\n    50000\n  dklen\n    20\n  saltlen\n    16\n  number of runs per test\n    10\n  Python\n    Python 3.3 on Linux AMD64\n  CPU\n    Intel i7-2860QM @ 2.50GHz\n\nChangelog\n=========\n\npbkdf2 0.1\n----------\n\n*Release date: 19-Oct-2013*\n\n- initial release of backports.pbkdf2",
