From b8454eebe380677789735fd6bad368af2e6b2d1e Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Mon, 7 Jul 2008 22:41:31 +0800 Subject: crypto: prng - Deterministic CPRNG This patch adds a cryptographic pseudo-random number generator based on CTR(AES-128). 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.
