73Digest::base - Digest base class
74
75=head1 SYNOPSIS
76
77 package Digest::Foo;
78 use base 'Digest::base';
79
80=head1 DESCRIPTION
81
82The C<Digest::base> class provide implementations of the methods
83C<addfile> and C<add_bits> in terms of C<add>, and of the methods
84C<hexdigest> and C<b64digest> in terms of C<digest>.
85
86Digest implementations might want to inherit from this class to get
87this implementations of the alternative I<add> and I<digest> methods.
88A minimal subclass needs to implement the following methods by itself:
89
90 new
91 clone
92 add
93 digest
94
95The arguments and expected behaviour of these methods are described in
96L<Digest>.
