Digest::base - Digest base class
package Digest::Foo; use base 'Digest::base';
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 the Digest manpage.
