Linux kernel crypto API provides ways to encrypt/decrypt data and to provide authentication info for the same. Some basic algorithms for this are gone over; hash algorithms for SHA1, SHA256, SHA512 and some basic cipher algorithms like AES / DES. Second part of the speak covers details how to implement a new cryptographic driver for one or more of these algorithms. In typical case this would be a new hardware accelerator driver for either a hash or cipher algorithm core. Driver level APIs required for these both are covered, in addition to the testing facilities provided by both kernel and userspace. In third part we go over performance and throughput measurements (openssl, tcrypt, IPSec), and how to optimize the driver to reach best possible results with these. Hardware vs. software cryptography performance is compared also with some TI SoCs used as reference platforms.
