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.
