TSIG-KEYGEN(8)			     BIND 9			  TSIG-KEYGEN(8)

NAME
     tsig-keygen - TSIG key generation tool

SYNOPSIS
     tsig-keygen [-a algorithm] [-h] [name]

DESCRIPTION
     tsig-keygen  is  an utility that generates keys for use with TSIG (Transac-
     tion Signatures) as defined in RFC 2845. The resulting keys  can  be  used,
     for  example, to secure dynamic DNS updates to a zone, or for the rndc com-
     mand channel.

     A domain name can be specified on the command line to be used as  the  name
     of the generated key. If no name is specified, the default is tsig-key.

OPTIONS
     -a algorithm
	    This  option specifies the algorithm to use for the TSIG key. Avail-
	    able choices are:  hmac-md5,  hmac-sha1,  hmac-sha224,  hmac-sha256,
	    hmac-sha384,  and  hmac-sha512.  The default is hmac-sha256. Options
	    are case-insensitive, and the "hmac-" prefix may be omitted.

     -h     This option prints a short summary of options and arguments.
