       key] [file...]

       [md5|md4|md2|sha1|sha|mdc2|ripemd160] [-c] [-d] [file...]

DESCRIPTION
       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.

OPTIONS
       -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.

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

       -binary
           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 "filename".

       -passin arg
           the private key password source. For more information about the
           format of arg see the PASS PHRASE ARGUMENTS section in openssl(1).

       -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 "filename".

       -signature filename
           the actual signature to verify.

       -hmac key
           create a hashed MAC using "key".

       -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

       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.
