From: Martin Willi Subject: [PATCH] crypto: poly1305 - Pass key as first two message blocks to each desc_ctx Date: Tue, 16 Jun 2015 11:34:16 +0200 Message-ID: <1434447256-6780-1-git-send-email-martin@strongswan.org> To: Herbert Xu , Steffen Klassert , linux-crypto@vger.kernel.org Return-path: Received: from revosec.ch ([5.148.177.19]:42223 "EHLO revosec.ch" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S934202AbbFPJet (ORCPT ); Tue, 16 Jun 2015 05:34:49 -0400 Sender: linux-crypto-owner@vger.kernel.org List-ID: The Poly1305 authenticator requires a unique key for each generated tag. This implies that we can't set the key per tfm, as multiple users set individual keys. Instead we pass a desc specific key as the first two blocks of the message to authenticate in update().
