Description:
Perl implementation of PBKDF2 password hash
PBKDF2 (part of the PKCS#5 standard) is a secure password hashing algorithm that uses the techniques of "key strengthening" to make the complexity of a brute-force attack arbitrarily high. The Crypt::PBKDF2 module supports SHA-1, SHA-2 and SHA-3 as the underlying hash functions natively and can also use arbitrary Digest-compatible classes. It allows for an arbitrary number of iterations of the hashing function, and a nearly unlimited output hash size (up to 2**32 - 1 times the size of the output of the backend hash). The hash is salted, as any password hash should be, and the salt may also be of arbitrary size.
