Did you know that the wolfSSL embedded SSL/TLS library supports ARMv8 as well as the Cryptography Extensions that it provides? wolfSSL is more than 10 times faster with AES and SHA256 operations the ARMv8 board we have been testing on (HiKey LeMaker) when using hardware acceleration versus software crypto!
