Re: [edk2-devel] [PATCH V5 0/3] SecureBoot: Support RSA 512 and RSA 384

["Sheng Wei" <w.sheng@intel.com>]

Here are my negative tests.
1) Enroll a RSA2048 Cert, execute an unsigned efi image.
2) Enroll a RSA2048 Cert, execute a RSA4096 signed efi image.
3) Enroll a RSA4096 Cert, execute a RSA3072 signed efi image.
4) Enroll a RSA4096 Cert to both DB and DBX, execute the RSA4096 signed efi image.

Test Result:
Get "Access Denied" when try to execute the efi image.

Thank you.
