# Digest::base(3p)

Digest base class

## NAME

Digest::base - Digest base class

## 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.
