how to sign a EFI image

  1. generate certificates

    bash -ex scripts/make_codesign_cert.sh
    
  2. sign a EFI image

    ./main sign --key key.pem --cert certificate.pem shimx64.efi shimx64.efi.signed
    
  3. sign a EFI image with detached signature

    ./main sign --key key.pem --cert certificate.pem -d shimx64.efi efi.signed
