From: Arek Kusztal Date: Wed, 1 Jun 2022 09:02:44 +0000 (+0100) Subject: cryptodev: add public key verify option X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2adb85292350bc1ea9efd4f87704a1e2aa38fa54;p=dpdk.git cryptodev: add public key verify option - Added key exchange public key verify option. For some elliptic curves public point in DH exchange needs to be checked, if it lays on the curve. Modular exponentiation needs certain checks as well, though mathematically much easier. This commit adds verify option to asym_op operations.
