-.Dt GZSIG 1
-.Os
-.Sh NAME
-.Nm gzsig
-.Nd gzip signing utility
-.Sh SYNOPSIS
-.Nm gzsig
-.Ic sign
-.Op Fl q | v
-.Op Fl f Ar secret_file
-.Ar privkey
-.Op Ar
-.Nm gzsig
-.Ic verify
-.Op Fl q | v
-.Op Fl f Ar secret_file
-.Ar pubkey
-.Op Ar
-.Sh DESCRIPTION
-.Nm
-embeds or verifies RSA PKCS #1 v2.0 or DSA SHA1 signatures in
-.Xr gzip 1
-compressed files using SSH identity keys or X.509 certificates.
-.Pp
-The
-.Ar file
-operands are processed in command-line order.
-If
-.Ar file
-is a single dash
-.Pq Sq -
-or absent,
-.Nm
-reads from the standard input.
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It Fl f Ar secret_file
-Indicates that the passphrase for the key should be read from
-.Ar secret_file
-instead of being supplied manually.
-.It Fl q
-Enable quiet mode.
-The options
-.Fl q
-and
-.Fl v
-are mutually exclusive;
-the last one specified takes precedence.
-.It Fl v
-Enable verbose mode.
-This is the default.
-The options
-.Fl q
-and
-.Fl v
-are mutually exclusive;
-the last one specified takes precedence.
-.It Ic sign
-Sign the input using the private key in
-.Ar privkey .
-.It Ic verify
-Verify the signature using the public key in
-.Ar pubkey .
-.El
-.Sh EXIT STATUS
-.Ex -std gzsig
-.Sh EXAMPLES
-Sign
-.Ar file1
-and
-.Ar file2
-with the SSH2 identity key in
-.Ar ~/.ssh/id_rsa :
-.Pp
-.Dl $ gzsig sign ~/.ssh/id_rsa file1 file2
-.Pp
-Sign
-.Ar file1
-with the SSH2 identity key, saving the signed file in
-.Ar file2 :
-.Pp
-.Dl $ gzsig sign ~/.ssh/id_rsa \*(Ltfile1 \*(Gtfile2
-.Pp
-Verify the signature on
-.Ar file1
-using the SSL certificate in
-.Ar /etc/ssl/server.crt :
-.Pp
-.Dl $ gzsig verify /etc/ssl/server.crt \*(Ltfile1
-.Sh SEE ALSO
-.Xr gzip 1 ,
-.Xr ssh-keygen 1 ,
