This is a subject that I know absolutely NOTHING about,...but, nevertheless, is interesting,...
Implementing SHA-2 in Active Directory Certificate Services, TectNet, June 15, 2015 (http://social.technet.microsoft.com/wiki/contents/articles/31296.implementing-sha-2-in-active-directory-certificate-services.aspx)
I even found several MASN Forum discussions on the subject:
SHA256-Hash and Some "Special" Characters, August 2014 (http://masm32.com/board/index.php?topic=3528.0),...and,...
File Checksum - MD5 - SHA1 etc.... January 2013 (http://masm32.com/board/index.php?topic=1343.0)
The second discussion has a zip file that contains: drizz's Crypto library for MASM. (It's like the Mother-Lode of crypto-stuff,...)
...Makes me want to become a spy,...:bgrin:
