.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \f(CW\*(C`Digest::MD2\*(C'\fR module allows you to use the \s-1RSA\s0 Data Security
Inc. \s-1MD2\s0 Message Digest algorithm from within Perl programs.  The
algorithm takes as input a message of arbitrary length and produces as
output a 128\-bit \*(L"fingerprint\*(R" or \*(L"message digest\*(R" 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.
