NAME

Digest::Perl::MD4 - Perl implementation of Ron Rivests MD4 Algorithm

DISCLAIMER

This is not C-code interface (like `Digest::MD5') but a Perl-only implementation of MD4 (like `Digest::Perl::MD5'). Because of this, it is slow but avoids platform specific complications. For efficiency you should use `Digest::MD4' instead of this module if it is available.

SYNOPSIS

     # Functional style
     use Digest::Perl::MD4 qw(md4 md4_hex md4_base64);

     $hash = md4 $data;
     $hash = md4_hex $data;
     $hash = md4_base64 $data;

     # OO style
     use Digest::Perl::MD4;

     $ctx = Digest::Perl::MD4->new;

     $ctx->add($data);
     $ctx->addfile(*FILE);

     $digest = $ctx->digest;
     $digest = $ctx->hexdigest;
     $digest = $ctx->b64digest;

MANIFEST

README          This file.
MD4.pm          The Perl code implementing Rivest's MD4 algorithm.
Digest-MD4.pm   A wrapper module called Digest::MD4.
test.pl         A test program for the MD4 module.

The MD4 module's interface should be compatible with the C-code MD4 module written by Mike McCauley <mikem@open.com.au>. The Digest-MD4.pm is provided which makes the MD4 module available as the shorter module Digest::MD4. It should not be installed as is if Mike's module is already installed. If you want both of these installed (e.g. multiple platforms are using the same installation), the adaptive aspects of Digest-MD4.pm will have to be merged with the Mike's actual MD4.pm code.

Assuming "Perl-site-lib" is one of the directories listed in @INC, install the module like this:

file            Perl-site-lib
----            ------------------
MD4.pm          Digest/Perl/MD4.pm
Digest-MD4.pm   Digest/MD4.pm           # if C-code MD4 is NOT installed
