      md5 - calculate a message-digest fingerprint (checksum) for a file

      md5 [ -t | -x | -sstring | filename(s) ]

      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 RSA.

      The following four options may be used in any combination, except that
      filename(s) must be the last objects on the command line.

      -sstring prints a checksum of the given "string".

      -t runs a built-in time trial.

      -x runs a built-in test script.

      filename(s) prints a checksum(s) for each of the files.


      RFC 1321 describes in detail the MD2, MD4, and MD5 message-digest

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