From 7c04bab710cd7ef9b1de61eca65d40dcb70f066d Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Thu, 30 Jul 2020 13:52:14 +0300 Subject: [PATCH] tests: AES-CTR encrypt test vectors Verify AES-CTR encryption implementation against the test vectors in NIST SP 800-38a. This implementations was already tested against AES SIV and EAX mode test vectors, but this adds more explicit testing against published CTR mode test vectors.
