From: tb Date: Thu, 1 Sep 2022 14:02:41 +0000 (+0000) Subject: Add a nicely licensed, table-driven test for SHA X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=55e6bb006c4feedf4443043c9ffb01bc7e2ec48a;p=openbsd Add a nicely licensed, table-driven test for SHA This tests covers the NIST vectors for SHA-{1,224,256,384,256} and will soon be able to replace the old SHA tests entirely.
