From: Sebastian Siewior Subject: [patch 3/3] change the XTEA test vectors. Date: Sun, 03 Feb 2008 13:55:27 +0100 Message-ID: <20080203130750.598243061@breakoint.cc> References: <20080203125524.339000971@breakoint.cc> Cc: linux-crypto@vger.kernel.org, Sebastian Siewior To: Herbert Xu Return-path: Received: from Chamillionaire.breakpoint.cc ([85.10.199.196]:34772 "EHLO Chamillionaire.breakpoint.cc" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1765057AbYBCNRa (ORCPT ); Sun, 3 Feb 2008 08:17:30 -0500 Content-Disposition: inline; filename=0003-crypto-change-the-XTEA-test-vectors.patch Sender: linux-crypto-owner@vger.kernel.org List-ID: The third test vector of ECB-XTEA-ENC fails for me all other are fine. I could not find a RFC or something else where they are defined. The test vector has not been modified since git started recording histrory. The implementation is very close (not to say equal) to what is available as Public Domain (they recommend 64 rounds and the in kernel uses 32). Therefore I belive that there is typo somewhere and tcrypt reported always *fail* instead of *okey*. This patch replaces input + result of the third test vector with result + input from the third decryption vector. The key is the same, the other three test vectors are also the reverse.
