https://bugzilla.tianocore.org/show_bug.cgi?id=2420 Based on the following package with changes to merge into CryptoPkg. https://github.com/microsoft/mu_plus/tree/dev/201908/SharedCryptoPkg Add the CryptoPei, CryptoDxe, and CryptoSmm modules that produce EDK II Crypto Protocols/PPIs that provide the same services as the BaseCryptLib class. In order to optimize the size of CryptoPei, CryptoDxe, and CryptoSmm modules for a specific platform, the FixedAtBuild PCD gEfiCryptoPkgTokenSpaceGuid.PcdCryptoServiceFamilyEnable is used to determine if a specific service is enabled or disabled. If a service is enabled, then a call is made to the BaseCryptLib service. If the service is disabled, then a DEBUG() message and ASSERT() are performed and a default return value is returned. This provides simple detection of a service that is disabled but is used by another module when DEBUG()/ASSERT() macros are enabled. The use of a FixedAtBuild PCD is required so the compiler and linker know each services enable/disable setting at build time and allows disabled services to be optimized away. CryptoPei supports both pre-mem and post-mem use cases. If CryptoPei is initially dispatched pre-mmem, the the register for shadow service is used so the Crypto PPI can be reinstalled post-mem.

# Produces the EDK II Crypto PPI using the library services from BaseCryptLib
|
|
# and TlsLib. PcdCryptoServiceFamilyEnable is used to enable the subset of
|
|
# available services. If this PEIM is dispatched before memory is discovered,
|
|
# the RegisterForShadow() feature is used to reload this PEIM into memory after
|
|
# memory is discovered.
