gzsig
embeds or verifies RSA PKCS #1 v2.0
or DSA SHA1 signatures in
gzip(1) compressed files using
SSH identity keys or X.509 certificates.
The file operands are processed in
command-line order. If file is a single dash
(‘-’) or absent, gzsig
reads from the
standard input.
The options are as follows:
-f
secret_file-q
-q
and
-v
are mutually exclusive; the last one specified
takes precedence.-v
-q
and -v
are mutually
exclusive; the last one specified takes precedence.sign
verify
The gzsig
utility exits 0 on
success, and >0 if an error occurs.
Sign file1 and file2 with the SSH2 identity key in ~/.ssh/id_rsa:
$ gzsig sign ~/.ssh/id_rsa file1
file2
Sign file1 with the SSH2 identity key, saving the signed file in file2:
$ gzsig sign ~/.ssh/id_rsa <file1
>file2
Verify the signature on file1 using the SSL certificate in /etc/ssl/server.crt:
$ gzsig verify /etc/ssl/server.crt
<file1
