OpenBSD Cryptographic Framework

The OpenBSD Cryptographic Framework (OCF) is a service virtualization layer for the uniform management of cryptographic hardware by an operating system. It is part of the OpenBSD Project, having been included in the operating system since OpenBSD 2.8 (December, 2000). Like other OpenBSD projects such as OpenSSH, it has been ported to other systems based…
