Digest-MD4
The Digest-MD4 module allows you to use the RSA Data Security Inc. MD4 Message Digest algorithm from within Perl programs. The algorithm takes as input a message of arbitrary length and produces as output a 128-bit fingerprint or message digest of the input.
The Digest-MD4 module provide a procedural interface for simple use, as well as an object oriented interface that can handle messages of arbitrary length and which can read files directly.
