From 4e5b9645e8f4a5924e15bfc575e302ee37a706bd Mon Sep 17 00:00:00 2001 From: Matt Caswell Date: Tue, 26 Mar 2013 15:39:50 +0000 Subject: [PATCH] Make binary curve ASN.1 work in FIPS mode. Don't check for binary curves by checking methods: the values will be different in FIPS mode as they are redirected to the validated module version.
