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.

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.
