From mboxrd@z Thu Jan 1 00:00:00 1970 From: Vitaly Chikunov Date: Sun, 06 Jan 2019 13:36:04 +0000 Subject: [RFC PATCH 0/4] crypto: Add EC-RDSA algorithm Message-Id: <20190106133608.820-1-vt@altlinux.org> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit List-Id: To: David Howells , Herbert Xu , Mimi Zohar , Dmitry Kasatkin , linux-integrity@vger.kernel.org, keyrings@vger.kernel.org, linux-crypto@vger.kernel.org, linux-kernel@vger.kernel.org This patchset changes akcipher api to support ECDSA style signature verification. Augments x509 parser to make it work with EC-RDSA certificates. And finally implements EC-RDSA (GOST 34.10) signature verification. It is intended to use in IMA for appraisal. Tested on x86_64 with openssl+gost-engine generated certificates.
