         dgst, md5, md4, md2, sha1, sha, mdc2, ripemd160 - message


         openssl dgst
         [-md5|-md4|-md2|-sha1|-sha|-mdc2|-ripemd160|-dss1] [-c] [-d]
         [-hex] [-binary] [-out filename] [-sign filename] [-verify

         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.


         -c  print out the digest in two digit groups separated by
             colons, only relevant if hex format output is used.
         -d  print out BIO debugging information.
             digest is to be output as a hex dump. This is the
             default case for a "normal" digest as opposed to a
             digital signature.
             output the digest or signature in binary form.
         -out filename
             filename to output to, or standard output by default.
         -sign filename
             digitally sign the digest using the private key in
         -verify filename
             verify the signature using the the public key in
             "filename".  The output is either "Verification OK" or
             "Verification Failure".
         -prverify filename
             verify the signature using the  the private key in
         -signature filename
             the actual signature to verify.
         -rand file(s)
             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.
             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.
