46.Sh DESCRIPTION
47The
48.Nm
49utility signs PE binary files using Authenticode scheme, as required by
50UEFI Secure Boot specification.
51Alternatively, it can be used to view and verify existing signatures.
52These options are available:
53.Bl -tag -width ".Fl l"
54.It Fl V
55Determine whether the file is signed.
56Note that this does not verify the correctness of the signature;
57only that the file contains a signature.
58.It Fl k
59Name of file containing the private key used to sign the binary.
60.It Fl c
61Name of file containing the certificate used to sign the binary.
62.It Fl o
63Name of file to write the signed binary to.
64.It Fl v
65Be verbose.
66.El
67.Sh EXIT STATUS
68The
69.Nm
70utility exits 0 on success, and >0 if an error occurs.
71.Sh EXAMPLES
72Generate self-signed certificate and use it to sign a binary:
73.Dl /usr/share/examples/uefisign/uefikeys testcert
74.Dl uefisign -c testcert.pem -k testcert.key -o signed-binary binary
75.Pp
