From da7f033ddc9fdebb3223b0bf88a2a2ab5b797608 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 31 Jul 2008 17:08:25 +0800 Subject: crypto: cryptomgr - Add test infrastructure This patch moves the newly created alg_test infrastructure into cryptomgr. This shall allow us to use it for testing at algorithm registrations.

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.
