     The digest functions output the message digest of a supplied
     file or files in hexadecimal form. They can also be used for
     digital signing and verification.

OOOOPPPPTTTTIIIIOOOONNNNSSSS
     -cccc  print out the digest in two digit groups separated by
         colons, only relevant if hhhheeeexxxx format output is used.

     -dddd  print out BIO debugging information.

     -hhhheeeexxxx
         digest is to be output as a hex dump. This is the
         default case for a "normal" digest as opposed to a
         digital signature.

         "Verification Failure".

         a file or files containing random data used to seed the
         random number generator, or an EGD socket (see
         RAND_egd(3)).  Multiple files can be specified separated
         by a OS-dependent character.  The separator is ;;;; for
         MS-Windows, ,,,, for OpenVMS, and :::: for all others.

     ffffiiiilllleeee............
         file or files to digest. If no files are specified then
         standard input is used.

     The digest of choice for all new applications is SHA1. Other
     digests are however still widely used.

     If you wish to sign or verify data using the DSA algorithm
     then the dss1 digest must be used.

     A source of random numbers is required for certain signing
     algorithms, in particular DSA.

     The signing and verify options should only be used if a
     single file is being signed or verified.
