Using the hardware crypto engine was once possible via the OCF cryptodev api.

Kernel part: http://www.mail-archive.com/[EMAIL PROTECTED]/msg02172.html OpenSSL Patch: http://www.mail-archive.com/[EMAIL PROTECTED]/msg02234.html I never tested it. The overhead of putting the data into the kernel and into the NPE and back again was amortized by hardware speed only above 1Kbyte of data length on the IXP4xx CPU. This was at least the result back then when I tested OCF-cryptodev with my driver.
