From: "Sukerkar, Amol N" <amol.n.sukerkar@intel.com>
This commit introduces a Unified Hash API to calculate hash using a
hashing algorithm specified by the PCD, PcdSystemHashPolicy. This library
interfaces with the various hashing API, such as, MD4, MD5, SHA1, SHA256,
SHA512 and SM3_256 implemented in CryptoPkg. The user can calculate the
desired hash by setting PcdSystemHashPolicy to appropriate value.

+/** @file
+ Implement image verification services for secure boot service
+
+ Caution: This file requires additional review when modified.
+ This library will have external input - PE/COFF image.
+ This external input must be validated carefully to avoid security issue like
+ buffer overflow, integer overflow.
+
+ DxeImageVerificationLibImageRead() function will make sure the PE/COFF image content
+ read is within the image buffer.
+
+ DxeImageVerificationHandler(), HashPeImageByType(), HashPeImage() function will accept
+ untrusted PE/COFF image and validate its data structure within this image buffer before use.
