NAME

       hmackeys - utility program for generating good HMAC-SHA1 keys

SYNOPSIS

       hmackeys [ keynames_filename ]

DESCRIPTION

       hmackeys writes files containing randomized 160-bit key values suitable for use by
       HMAC-SHA1 in support of Bundle Authentication Block processing, Bundle Relay Service
       connections, or other functions for which symmetric hash computation is applicable.  One
       file is written for each key name presented to hmackeys; the content of each file is 20
       consecutive randomly selected 8-bit integer values, and the name given to each file is
       simply "keyname.hmk".

       hmackeys operates in response to the key names found in the file keynames_filename, one
       name per file text line, if provided; if not, hmackeys prints a simple prompt (:) so that
       the user may type key names directly into standard input.

       When the program is run in interactive mode, either enter 'q' or press ^C to terminate.

EXIT STATUS

       "0" Completion of key generation.

EXAMPLES

       hmackeys
           Enter interactive HMAC/SHA1 key generation mode.

       hmackeys host1.keynames
           Create a key file for each key name in host1.keynames, then terminate immediately.

FILES

       No other files are used in the operation of hmackeys.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

       The following diagnostics may be issued to the logfile ion.log:

       Can't open keynames file...
           The keynames_filename specified in the command line doesn't exist.
