In kernels that support it cryptodev can provide the userspace with information (see SIOP_FLAG_KERNEL_DRIVER_ONLY) on whether the driver for a particular algorithm is hardware accelerated or not. GnuTLS uses that information and does not use software algorithms in kernel. regards, Nikos _______________________________________________ Cryptodev-linux-devel mailing list Cryptodev-linux-devel@gna.org https://mail.gna.org/listinfo/cryptodev-linux-devel
