From 17f0f4a47df9aea9ee26c939f8057c35e0be1847 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Thu, 14 Aug 2008 22:15:52 +1000 Subject: crypto: rng - RNG interface and implementation This patch adds a random number generator interface as well as a cryptographic pseudo-random number generator based on AES. It is meant to be used in cases where a deterministic CPRNG is required. One of the first applications will be as an input in the IPsec IV generation process.
