# Digest::MD2(3pm)

Perl interface to the MD2 Algorithm

## NAME

Digest::MD2 - Perl interface to the MD2 Algorithm

## SYNOPSIS

```
 # Functional style
 use Digest::MD2  qw(md2 md2_hex md2_base64);
 $digest = md2($data);
 $digest = md2_hex($data);
 $digest = md2_base64($data);
 # OO style
 use Digest::MD2;
 $ctx = Digest::MD2->new;
 $ctx->add($data);
 $ctx->addfile(*FILE);
 $digest = $ctx->digest;
 $digest = $ctx->hexdigest;
 $digest = $ctx->b64digest;
```

## DESCRIPTION

The `"Digest::MD2"` module allows you to use the RSA Data Security Inc. MD2 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::MD2"` programming interface is identical to the interface of `"Digest::MD5"`.
