Continuing on in a series of blogs about the VIA ARTiGO A2000, Fea-nux has been experimenting with VIA PadLock, which is built in security in VIA processors. This includes hardware support for AES encryption. With PadLock enabled, OpenSSL was 45x faster and Apache was almost twice as fast. There is both practical advice and results in this blog!
"Once the padlock_aes module is loaded, it can be used by programs such as OpenSSL. First, run openssl engine, and you should see output such as (padlock) VIA PadLock: RNG ACE2 PHE(8192) PMM that indicates that the VIA PadLock engine support has been compiled in. To see the difference with and without hardware encryption, for example, try running openssl speed -evp aes256."
