NAME

uefisign — UEFI Secure Boot signing utility

SYNOPSIS

uefisign -k key -c certificate -o output [-v] file

uefisign -V [-v] file

DESCRIPTION

The uefisign utility signs PE binary files using Authenticode scheme, as required by UEFI Secure Boot specification. Alternatively, it can be used to view and verify existing signatures. These options are available:

-V: Determine whether the file is signed. Note that this does not verify the correctness of the signature; only that the file contains a signature.
-k: Name of file containing the private key used to sign the binary.
-c: Name of file containing the certificate used to sign the binary.
-o: Name of file to write the signed binary to.
-v: Be verbose.

EXIT STATUS

The uefisign utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

Generate self-signed certificate and use it to sign a binary:

/usr/share/examples/uefisign/uefikeys
  testcert

uefisign -c testcert.pem -k
  testcert.key -o signed-binary binary

View signature:

uefisign -Vv binary

The uefisign command appeared in FreeBSD 10.2.
