The Linux crypto subsystem has a poor reputation when it comes to usability of its API. This is not entirely undeserved, but it makes sense to take a closer look at why the current API was designed the way it is and what we are doing to improve it. Also, we'll take a look at some examples of how a better understanding of the underlying crypto on the part of the crypto API user would have resulted in much better (and more secure) code.

Ard Biesheuvel is employed by Arm Ltd. to contribute to open source projects such as Tianocore and the Linux kernel. His mission is to make security and hardening features that exist for other architectures equally well supported on ARM, or better. His contributions to the arm64 Linux kernel cover things like KASLR, per-task stack cookies and most of the accelerated crypto code.
