digest

Name
     digest - calculate a message digest

Synopsis
     /usr/bin/digest -l | [-v] -a algorithm [file]...

Description
     The digest utility calculates  the  message  digest  of  the
     given  files or stdin using the algorithm specified. If more
     than one file is given, each line of output is the digest of
     a single file.

Options
     The following options are supported:

     -a algorithm
                     Specifies the name of the algorithm  to  use
                     during the encryption or decryption process.
                     See USAGE, Algorithms, for details.


     -l
                     Displays list of algorithms available on the
                     system.  This  list  can change depending on
                     the  configuration  of   the   cryptographic
                     framework.


     -v
                     Verbose output. Includes the algorithm  name
                     and filename in the output.

Usage
  Algorithms
     These algorithms are provided by  the  Cryptographic  Frame-
     work. Each algorithm supported by the command is an alias of
     the PKCS #11 mechanism for easier access. For example,  sha1
     is an alias to CKM_SHA_1.


     These aliases are used with the  -a  option  and  are  case-
     sensitive.

Examples
     Example 1 Simulating Output


     The following example simulates output of the common  md5sum
     program:


       example$ digest -v -a md5 /usr/bin/vi
       md5 (/usr/bin/vi) = e4e3588c5212903847c66d36b1a828a5

     Example 2 Digesting a File


     The following example generates the sha1 digest of the  file
     /etc/motd:


       example$ digest -a sha1 /etc/motd
       9498a4f5303d056ad3ecae826b59f41448d63790



     Example 3 Generating a Directory Manifest


     The following example generates a  directory  manifest  with
     sha1:


       example$ digest -v -a sha1 /usr/lib/inet/*
       sha1 (/usr/lib/inet/certdb) = f6d43e6e395d50db24d34e4af4828598c8918b16
