Tom,
Let me know if you get any useful offline answers.  From our experience, there 
are some licensed 3rd party solutions that are tiny but aren’t cheap.  
The problem is parts of any encryption runs the risk of triggering government 
laws about encryption.  So the owners of Tianocore made the decision to pull in 
OpenSSL as a whole to put the problem onto the user of TC.  
Making smaller versions of OpenSSL means you have a lot of work to incorporate 
newer versions.

Subject: [edk2] Pkcs7 crypto verification without openSSL Hi,

Are there any plans for a crypto library that does not pull in openSSL? When I 
try to add BaseCryptLib to be able to use FmpAuthenticationLib, my driver size 
baloons significantly (increase of ~0x30000) and it seems like a basic public 
SHA256 crypto check library should not be _that_ large?

Cheers,
Tom
