Hi Mike, Jian and Jiewen,

Based on our discussion, I have compiled the enhancements/changes to be made to BaseHashApiLib instance in CryptoPkg in the Bugzilla, https://bugzilla.tianocore.org/show_bug.cgi?id=2511.

Please go over the changes and provide comments/feedback. Once I have confirmation that I have captured all the identified changes, I will begin implementation.
