Todd Short 0113ec8460 Implement AES-GCM-SIV (RFC8452) ... Fixes #16721 This uses AES-ECB to create a counter mode AES-CTR32 (32bit counter, I could not get AES-CTR to work as-is), and GHASH to implement POLYVAL. Optimally, there would be separate polyval assembly implementation(s), but the only one I could find (and it was SSE2 x86_64 code) was not Apache 2.0 licensed. This implementation lives only in the default provider; there is no legacy implementation. The code offered in #16721 is not used; that implementation sits on top of OpenSSL, this one is embedded inside OpenSSL. Full test vectors from RFC8452 are included, except the 0 length plaintext; that is not supported; and I'm not sure it's worthwhile to do so.
