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
   

   the efi.signed file will onlyl contain the signature itself which can be used by set_authenticode
