    §W 5

  138. Mancho has left

  139. MattJ

    Flow, the logic failure is that the client doesn't need to wait for an acknowledgement before it can send more requests (putting aside the normal BOSH rules about multiple open requests)

  140. dwd

    Flow, What PR#4 is saying doesn't immediately seem wrong - that one could use HTTP responses as acks - but the code doesn't appear to do this, and also what MattJ says.

  141. jere has joined

  142. Yagiza has left

  143. Flow

    Thanks MattJ, dwd. I think OPs main problem is using BOSH with only one (processing) thread. That will always cause a delay in one of the directions (if I'm not mistaken).

  190. Flow

    Zash: blocking http requests?

  191. Zash

    daniel: some SCRAM changes there, maybe

  192. Zash

    Flow: Send HTTP request, wait for response before continuing with processing, have a bad time.

  193. Flow

    well that's what I think is happening in case only one thread is used with jbosh

  194. Zash

    Oh it's a client side library?

  195. Zash

    The coffee, it does nothing :|

  196. Zash

    Hey, Guus or dwd, does Openfire still do DIGEST-MD5?

  197. Zash

    Given the recent rush to hate on SHA-1, I'm impressed that nobody cares that DIGEST-MD5 is still around.

  198. sonny has left

  199. daniel

    Zash: well the 24 hours news cycle and the general alarmism applies to it security news as well

  200. Holger

    In 2 h 45 minutes

  207. dwd

    Zash, DIGEST-MD5's security state hasn't really changed; the biggest weakness remains that you can churn through a lot of MD5's each second, and DIGEST-MD5 only uses three per cycle.

  208. waqas has joined

  209. dwd

    Zash, The fact it uses MD5 is *almost* irrelevant.

  210. jonasw

    isn’t it with DIGEST-MD5 that, like with PLAIN, it is enough to listen in on the connection to be able to authenticate as that user later?

  211. jonasw

    (I haven’t looked into it; it has been deprecated so I didn’t bother implementing it)

  212. Zash glares at daniel

  213. Tobias

    not to forget the interop issues with digest-md5

  214. vurpo has left

  216. Zash

    dwd: I'm sure we'll receive bug reports about SCRAM-SHA-1 being terrible because SHA-1 is broken soon.

  217. dwd

    Tobias, Oh, there are lots of problems. But using MD5 isn't really one of them.

  218. dwd

    jonasw, No, it's not subject to replay.

  219. Tobias

    dwd, reply with "Patches welcome!" :)

  220. Zash

    What about active MITM?

  221. dwd

    Zash, No channel binding, so yeah, an active MITM can work.

  222. dwd

    Zash, But couldn't replay, still.

  223. uc has left

  224. uc has joined

  225. Zash

    dwd: I remember there being issues with SCRAM if you could get a client to try to auth with you.

  226. dwd

    Zash, Only in as much as you can potentially brute-force the SHA-1 and extract the plaintext equiv in a reasonable timeframe these days.
