wolfSSL now supports ARMv8! Significant gains are seen when using the crypto hardware acceleration. wolfSSL is more than 10 times faster with AES and SHA256 operations on a HiKey (LeMaker version) board when using hardware acceleration vs software!!! If building an IoT project requiring fast, secure crypto/TLS with a small memory footprint size, contact wolfSSL at facts@wolfssl.com.
For information about the board used see http://www.lemaker.org/product-hikey-specification.html
