    What is encryption algorithm being used? There are a number that are available in the kernel.
    Sometimes, real fast is almost as good as real time.

    I was under the impression they wanted to keep asymmetric encryption algorithms out of the kernel for performance reasons. To be honest, I'm not sure if they've added them or not but I know this was the thinking around the time they wanted to add IPSec support to the kernel. Can you use OpenSSL libraries? I know RSA is supported there.

    This makes sense. Looking at the algorithms supported, they all seem to be symmetric, such as AES, Twofish, Blowfish, DES, etc.
