RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3853 This is the Cryptographic library instance for SEC. The motivation of this library is to support SHA384 in SEC phase for Td guest. So only Hash/CryptSha512.c is included which supports SHA384 and SHA512. Other cryptographics are added with the null version, such as CryptMd5Null.c.
