2008-07-10crypto: prng - Deterministic CPRNGNeil Horman
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. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
