Note: If you issue the command: openssl engine padlock

You will probably get this in return: (padlock) VIA PadLock (no-RNG, ACE)

From what I have read this deals with VIA's RNG being a bit buggy or insecure or something.

Getting padlock to work: (please feel free to help with the formatting of the page. I dont wiki often)


Add to /etc/modprobe.d/modprobe.conf:

$ alias aes padlock

Benchmarks without padlock (3 runs):

$ openssl speed -evp aes-128-cbc

Output:

$ OpenSSL 1.0.0e 6 Sep 2011

Add to /etc/ssl/openssl.cnf (before [new_oids] section):


openssl_conf = openssl_def

[openssl_def]
engines = openssl_engines

[openssl_engines]
padlock = padlock_engine

[padlock_engine]
