From 7a4adb5268ae71260c86788ccdeb7a699c80ee0a Mon Sep 17 00:00:00 2001 From: Kenny Root Date: Wed, 9 Oct 2013 10:14:35 -0700 Subject: Add support for ECDSA signatures This adds support for key version 5 which is an EC key using the NIST P-256 curve parameters. OTAs may be signed with these keys using the ECDSA signature algorithm with SHA-256.
