Switch to AES-SIV. stupidgcm: add GCM-SIV benchmark 2016-09-25T18:04:55+00:00 Jakob Unterwurzacher 2016-09-25T18:04:33+00:00 urn:sha1:0e277ba19e3a18093c33d3927739031b76892de3 On a CPU without AES-NI: $ go test -bench .

However, the GCM operations that stupidgcm uses never call that function. To guard against that ever changing, set a dummy locking callback that crashes the app. stupidgcm: skip tests on Go 1.4 and older 2016-05-04T22:09:08+00:00 Jakob Unterwurzacher 2016-05-04T20:34:52+00:00 urn:sha1:906172938afcf40418d78d825ee4cd2b9363d643 Quoting from the patch: We compare against Go's built-in GCM implementation. Since stupidgcm only supports 128-bit IVs and Go only supports that from 1.5 onward, we cannot run these tests on older Go versions.
