Add support for RSA 2048 SHA 256 signing and verification encoded in a PI FFS GUIDED Encapsulation Section. The primary use case of this feature is in support of signing and verification of encapsulated FVs for Recovery and Capsule Update, but can potentially be used for signing and verification of any content that can be stored in a PI conformant FFS file. Signing operations are performed from python scripts that wrap OpenSsl command line utilities. Verification operations are performed using the OpenSsl libraries in the CryptoPkg.
The guided encapsulation sections uses the UEFI 2.4 Specification defined GUID called EFI_CERT_TYPE_RSA2048_SHA256_GUID. The data layout for the encapsulation section starts with the UEFI 2.4 Specification defined structure called EFI_CERT_BLOCK_RSA_2048_SHA256 followed immediately by the data. The signing tool included in these patches performs encode/decode operations using this data layout. HashType is set to the UEFI 2.4 Specification defined GUID called EFI_HASH_ALGORITHM_SHA256_GUID.

} EFI_CERT_BLOCK_RSA_2048_SHA256;
MdePkg/Include/Protocol/Hash.h
=================================
#define EFI_HASH_ALGORITHM_SHA256_GUID \
{ \
0x51aa59de, 0xfdf2, 0x4ea3, {0xbc, 0x63, 0x87, 0x5f, 0xb7, 0x84, 0x2e, 0xe9 } \
}
The verification operations require the use of public key(s). A new PCD called gEfiSecurityPkgTokenSpaceGuid.PcdRsa2048Sha256PublicKeyBuffer is added to the SecurityPkg that supports one or more SHA 256 hashes of the public keys. A SHA 256 hash is performed to minimize the FLASH overhead of storing the public keys. When a verification operation is performed, a SHA 256 hash is performed on EFI_CERT_BLOCK_RSA_2048_SHA256.PublicKey and a check is made to see if that hash matches any of the hashes in the new PCD. It is recommended that this PCD always be configured in the DSC file as storage type of [PcdsDynamixExVpd], so the public keys are stored in a protected read-only region.
While working on this feature, I noticed that the CRC32 signing and verification feature was incomplete. It only supported CRC32 based verification in the DXE Phase, so the attached patches also provide support for CRC32 based verification in the PEI Phase.
I also noticed that the most common method for incorporating guided section extraction libraries was to directly link them to the DXE Core, which is not very flexible. The attached patches also add a generic section extraction PEIM and a generic section extraction DXE driver that can each be linked against one or more section extraction libraries. This provides a platform developer with the option of providing section extraction services with the DXE Core or providing section extraction services with these generic PEIM/DXE Drivers.
