[edk2-devel] [PATCH v3 2/3] CryptoPkg: BaseCryptLib: Add unit tests (Host and Shell based)

[Matthew Carlson]

Hey Mike,

1. I'll move it for v4.
2. I'll remove that, thanks!
3. I'll fix that as well, good spot.
4. It's mostly the same except for the different CrtWrappers
5. We need a host-specific CrtWrapper since the regular one has a bunch of
conflicts with regular C98, but there are a few functions that since we're
building no std mode of OpenSSL we still need to provide.
6. That would be my guess- this is largely based on the edk2-staging HBFA
branch and I've had to reverse engineer some of the steps for
generating the test data. I fixed the instructions.
