Subject: [PATCH 13/18] crypto: testmgr - add DH test vectors for key generation
Date:   Wed,  1 Dec 2021 01:48:53 +0100
Message-Id: <20211201004858.19831-14-nstange@suse.de>
In-Reply-To: <20211201004858.19831-1-nstange@suse.de>

Now that all DH implementations support ephemeral key generation triggered
by passing a ->key_size of zero to ->set_secret(), it's certainly
worthwhile to build upon the testmgr's do_test_kpp() ->genkey facility to
test it.

Add two ->genkey DH test vectors to the testmgr, one for the RFC 7919
ffdhe2048 group and another one for the RFC 3526 modp2048 group.

All required values have been generated with OpenSSL.
