YAFIC-SIGN(1)		    General Commands Manual		 YAFIC-SIGN(1)

NAME
       yafic-sign, yafic-check -- Signature utilities for yafic(1)

SYNOPSIS
       yafic-sign [-Vhp] [-c] keyfile file

       yafic-check [-Vhp] keyfile file

DESCRIPTION
       yafic-sign  cryptographically signs file	using the key keyfile.	yafic-
       check (which is simply another name for yafic-sign -c) verifies a  file
       against its signature.

       keyfile is expected to be an RSA	or DSA key. See	openssl(1), genrsa(1),
       gendsa(1), and specifically:

	      http://www.openssl.org/docs/HOWTO/keys.txt

       Signature files have the	same name as  file,  but  with	the  extension
       .sig.

OPTIONS
       The options are as follows:

       -V     Display version information.

       -h     Display help summary.

       -p     Expect keyfile to	be a public key	rather than a private key.

       -c     Instead of signing file, file is checked against its signature.

RETURN VALUES
       Both yafic-sign and yafic-check exit with one of	the following values:

       0      file was successfully signed or verified

       1      An error occurred.

       2      There  was  a  problem with the arguments	given to yafic-sign or
	      yafic-check.

       3      The verification of file against its signature failed.
