Oh, I'm dense, didn't correctly parse that 4309 was referring back to 3610 for the actual test vectors. I'll see what I can do with those... > I don't think theres anything wrong with the vectors > your're using below, but you may want to add the vectors from 3610 just to > imrpove the testing. I think I'd drop some of the ones in the initial patch in favor of adding some from 3610, rather than simply adding more. The coverage is already pretty good, increasing the number of vectors shouldn't really be necessary, but it would definitely be nice to have vectors that are already publicly published and verified. -- Jarod Wilson jarod@xxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
