    andyp, I haven't any big experience with cryptography too, but I think we can only verify validity of the capsule, because we don't have ASUS/Asrock/etc. private keys.
    There are definitely RSA2048 and SHA256 there, look at his definitions.
    Code:
    typedef struct {
  WIN_CERTIFICATE   Hdr;
  EFI_GUID          CertType;
//  UINT8            CertData[1];
//    EFI_CERT_BLOCK_RSA_2048_SHA256  CertData;
} WIN_CERTIFICATE_UEFI_GUID_1;

typedef struct {
    WIN_CERTIFICATE_UEFI_GUID_1      Hdr;        // 24
    EFI_CERT_BLOCK_RSA_2048_SHA256   CertData;   // 16+256+256
} AMI_CERTIFICATE_RSA2048_SHA256;

typedef struct {
    AMI_CERTIFICATE_RSA2048_SHA256   SignCert;   // 24+16+256+256
    EFI_CERT_BLOCK_RSA_2048_SHA256   RootCert;   // 16+256+256
} FW_CERTIFICATE;
    I don't know exactly, if the capsule can be signed with out own key - I hope so, but for there is no need to do it, because "afuwin64 /gan" disables the header verification and flashes modified image as is.

    Hi

    We can only verify. But it would be handy as often people mod ASUS EFIs and then get caught by the verification failed msg. I didn't know about the /gan flag though.

    I have found those structs. Was having a play last night but didn't get far.

    Thanks
    Andy

    Could the problem be that these bios files also contain a UEFI component?

    Because that's really what it is. It inserts code to generate a SLIC table using the EFI API at boot. It only worked on a few boards. SSV2 is an outdated term really - it referred to AMI BIOS mods where the modules were all kept the same size (MSI boards needed it). I think it meant Super Static V2 - which actually has no meaning at all these days.
