pbkdf2_hmac(p1, p2, p3, p4, p5)

public

Parameters

pass - string
salt - string - should be at least 8 bytes long.
iter - integer - should be greater than 1000. 20000 is better.
keylen - integer
digest - a string or OpenSSL::Digest object.

Available in OpenSSL 0.9.4.

Digests other than SHA1 may not be supported by other cryptography libraries.
