From dd475dcd3f8562b8c87455b715abf8b52f37d045 Mon Sep 17 00:00:00 2001 From: Stefan Budeanu Date: Tue, 10 Nov 2015 16:33:25 -0500 Subject: [PATCH] test: increase crypto strength for FIPS standard Use stronger crypto (larger keys, etc.) for arbitrary tests so they will pass in both FIPS and non-FIPS mode without altering the original intent of the test cases.
