The embedded SSL/TLS library wolfSSL, has support for 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 the email address firstname.lastname@example.org. Come stop by the wolfSSL booth at ARM TechCon!
