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.
