NAME

       Crypt::PBKDF2::Hash - Abstract role for PBKDF2 hashing algorithms.

VERSION

       version 0.161520

METHODS

   hash_len()
       Returns the length (in bytes) of the hashes this algorithm generates.

   generate($data, $key)
       Generate strong pseudorandom bits based on the $data and $key

   to_algo_string()
       Return a string representing any optional arguments this object was created with, for use
       by Crypt::PBKDF2's "generate" and "encode_string" methods. May return undef if no
       arguments are required, in which case none will be serialized and "from_algo_string" won't
       be called on reading the hash.

   from_algo_string($str)
       Given a string as produced by "from_algo_string", return an instance of this class with
       options corresponding to those in $str. If no options are expected, it's permissible for
       this method to throw an exception.
