As of this writing, I don't have access to a machine that has AES-NI instructions. Would you be willing to test code if AES-NI support is added to loop-AES? Most of the testing would be done as unprivileged userspace program. After it runs fine in userspace, then the code gets copied to kernel driver. -- Jari Ruusu 1024R/3A220F51 5B 4B F9 BB D3 3F 52 E9 DB 1D EB E3 24 0E A9 DD - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
