+.TH MD5 1 "Feb 14, 1994"
+.SH NAME
+md5 \- calculate a message-digest fingerprint (checksum) for a file
+.SH SYNOPSIS
+.B md5
+[ -p | -t | -x | -sstring | filename(s) ]
+.SH DESCRIPTION
+.B md5
+takes as input a message of arbitrary length and produces
+as output a 128-bit "fingerprint" or "message digest" of the input.
+It is conjectured that it is computationally infeasible to produce
+two messages having the same message digest, or to produce any
+message having a given prespecified target message digest.
+The MD5 algorithm is intended for digital signature applications, where a
+large file must be "compressed" in a secure manner before being
+encrypted with a private (secret) key under a public-key cryptosystem
+such as
+.I RSA.
+.SH OPTIONS
+The following four options may be used in any combination, except
+that
+.B "filename(s)"
+must be the last objects on the command line.
+.in +5
+.PP
+.B -sstring
+prints a checksum of the given "string".
+.PP
+.B -p
+echos stdin to stdout and appends the MD5 sum to stdout.
+.PP
+.B -t
+runs a built-in time trial.
+.PP
+.B -x
+runs a built-in test script.
+.PP
+.B filename(s)
+prints a checksum(s) for each of the files.
+.SH "SEE ALSO"
+.BR cksum (1)
+.PP
+RFC 1321 describes in detail the MD2, MD4, and MD5 message-digest algorithms.
+.SH ACKNOWLEDGEMENTS
+This program is placed in the public domain for free general use by
+RSA Data Security.
