From a9dc62988600e57cabcca9b357cde4df8ee61fb5 Mon Sep 17 00:00:00 2001 From: Dimitri John Ledkov Date: Mon, 30 Oct 2023 14:05:14 +0200 Subject: crypto: drbg - update FIPS CTR self-checks to aes256 When originally drbg was introduced FIPS self-checks for all types but CTR were using the most preferred parameters for each type of DRBG. Update CTR self-check to use aes256. This patch updates code from 541af946fe ("crypto: drbg - SP800-90A Deterministic Random Bit Generator"), but is not interesting to cherry-pick for stable updates, because it doesn't affect regular builds, nor has any tangible effect on FIPS certifcation.
