GZSIG(1) OpenBSD Reference Manual GZSIG(1)NAMEgzsig - gzip signing utility
SYNOPSISgzsig sign [-q] [-f secret_file] privkey [file ...]
gzsig verify [-q] [-f secret_file] pubkey [file ...]
DESCRIPTIONgzsig embeds or verifies RSA PKCS #1 v2.0 or DSA SHA1 signatures in
gzip(1) compressed files using SSH identity keys or X509 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
Indicates that the passphrase for the key should be read from
secret_file instead of being supplied manually.
-q Enable quiet mode.
sign Sign the input using the private key in privkey.
verify Verify the signature using the public key in pubkey.
EXIT STATUS
The gzsig utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
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
