    NSA has stopped recommending P-256, SHA-256, and AES-128: https://www.nsa.gov/ia/programs/suiteb_cryptography/index.shtml …. A recent previous version: https://web.archive.org/web/20150403110658/https://www.nsa.gov/ia/programs/suiteb_cryptography/index.shtml …

        @BRIAN_____ is the mobile site showing something different because those are the same curves and values as the archive?

        @adammcrosby That seems to be the case. The page is totally different on desktop.

        @BRIAN_____ I find this intriguing, given the earlier commonly held knowledge (after Schneier) about AES-256 being no stronger than 128...

        Replying to @gsnedders

        @gsnedders That's not accurate. the thinking was that AES-256 is poor w.r.t cost:benefit vs AES-128. Worth reconsidering that for >1 reason.

        @BRIAN_____ @munin does that mean they’re potentially broken? Or that the NSA doesn’t recommend them because they’re problematic to break?

        @McLean0 @BRIAN_____ @sleevi_ I don't think that the browsers will change their position on TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, right?

        @yuhong2 @BRIAN_____ @sleevi_ It's too bad there's no rationale provided for NSA's change. Extra safety margin? Crypto break through?

        @BRIAN_____ They may also have just decided that varying standards for SECRET and TOP SECRET didn't make logistical sense.
