Subject: [PATCH v5 10/10] integrity: support EC-RDSA signatures for asymmetric_verify
Date: Sun, 24 Feb 2019 09:08:28 +0300 [thread overview]
Message-ID: <20190224060828.2527-11-vt@altlinux.org> (raw)
In-Reply-To: <20190224060828.2527-1-vt@altlinux.org>
Allow to use EC-RDSA signatures for IMA by determining signature type by
the hash algorithm name. This works good for EC-RDSA since Streebog and
EC-RDSA should always be used together.
