SYNOPSIS

package Digest::Foo;
use base 'Digest::base';

DESCRIPTION

The "Digest::base" class provide implementations of the methods "addfile" and "add_bits" in terms of "add", and of the methods "hexdigest" and "b64digest" in terms of "digest".

Digest implementations might want to inherit from this class to get this implementations of the alternative add and digest methods. A minimal subclass needs to implement the following methods by itself:

    new
    clone
    add
    digest

The arguments and expected behaviour of these methods are described in Digest.
