Subject: [PATCH v6 08/13] crypto: ecc - Add NIST P521 curve parameters
Date: Tue, 12 Mar 2024 14:36:13 -0400 [thread overview]
Message-ID: <20240312183618.1211745-9-stefanb@linux.vnet.ibm.com> (raw)
In-Reply-To: <20240312183618.1211745-1-stefanb@linux.vnet.ibm.com>
From: Stefan Berger <stefanb@linux.ibm.com>
Add the parameters for the NIST P521 curve and define a new curve ID
for it. Make the curve available in ecc_get_curve.
Signed-off-by: Stefan Berger <stefanb@linux.ibm.com>
