.SH DESCRIPTION
.IX Header "DESCRIPTION"
The \f(CW\*(C`Digest::MD2\*(C'\fR 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.
.PP
The \f(CW\*(C`Digest::MD2\*(C'\fR programming interface is identical to the interface
of \f(CW\*(C`Digest::MD5\*(C'\fR.
