2473 This function receives a PKCS7 formatted signature, and then verifies that
2474 the specified Enhanced or Extended Key Usages (EKU's) are present in the end-entity
2475 leaf signing certificate.
2476 Note that this function does not validate the certificate chain.
2478 Applications for custom EKU's are quite flexible. For example, a policy EKU
2479 may be present in an Issuing Certificate Authority (CA), and any sub-ordinate
2480 certificate issued might also contain this EKU, thus constraining the
2481 sub-ordinate certificate. Other applications might allow a certificate
2482 embedded in a device to specify that other Object Identifiers (OIDs) are
2483 present which contains binary data specifying custom capabilities that
2484 the device is able to do.
2486 @param[in] Pkcs7Signature The PKCS#7 signed information content block. An array
2487 containing the content block with both the signature,
2488 the signer's certificate, and any necessary intermediate
2490 @param[in] Pkcs7SignatureSize Number of bytes in Pkcs7Signature.
2491 @param[in] RequiredEKUs Array of null-terminated strings listing OIDs of
2492 required EKUs that must be present in the signature.

2494 @param[in] RequireAllPresent If this is TRUE, then all of the specified EKU's
2495 must be present in the leaf signer. If it is
2496 FALSE, then we will succeed if we find any
2497 of the specified EKU's.
2499 @retval EFI_SUCCESS The required EKUs were found in the signature.
