Author: jhb Date: Wed Apr 24 00:16:39 2019 New Revision: 346616 URL: https://svnweb.freebsd.org/changeset/base/346616 Log: Run the plain SHA digest tests from NIST. Pass in an explicit digest length to the Crypto constructor since it was assuming only sessions with a MAC key would have a MAC. Passing an explicit size allows us to test the full digest in HMAC tests as well.
