RMD160(1)                  OpenBSD Reference Manual                  RMD160(1)

     rmd160 - calculate a message-digest fingerprint (checksum) for a file

     rmd160 [-ptx] [-s string] [file ...]

     rmd160 takes as input a message of arbitrary length and produces as out-
     put a 160-bit "fingerprint" or "message digest" of the input.  It is con-
     jectured 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 RMD-160 algorithm is intended
     for digital signature applications, where a large file must be "com-
     pressed" in a secure manner before being encrypted with a private (se-
     cret) key under a public-key cryptosystem such as RSA.

     The following four options may be used in any combination and must pre-
     cede any files named on the command line.  The RMD-160 sum of each file
     listed on the command line is printed after the options are processed.

     -s string   Prints a checksum of the given string.

     -p          Echos stdin to stdout and appends the RMD-160 sum to stdout.

     -t          Runs a built-in time trial.

     -x          Runs a built-in test script.

     cksum(1),  md5(1),  sha1(1)

     RMD-160 is part of the ISO draft standard  on dedicated hash functions.

     This program is placed in the public domain for free general use by RSA
     Data Security.
