=head1 NAME

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

=head1 VERSION

version 0.161520

=head1 METHODS

=head2 hash_len()

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

=head2 generate($data, $key)

Generate strong pseudorandom bits based on the C<$data> and C<$key>

=head2 to_algo_string()

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

=head2 from_algo_string($str)

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