GZSIG(1)		   OpenBSD Reference Manual		      GZSIG(1)

NAME
     gzsig - gzip signing utility

SYNOPSIS
     gzsig sign [-q] [-f secret_file] privkey [file ...]
     gzsig verify [-q] [-f secret_file] pubkey [file ...]

DESCRIPTION
     gzsig 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
