Nadim,

The only major difference I see (assuming you're asking about the product and not the threats Cooper lays out) is the persistence. It appears you can set up projects and store encrypted data on their servers. This certainly opens you up to other threats but I don't see it serving the same market as CryptoCat, namely it's going after a business audience that just doesn't want Google having all their files/chats/etc in the clear on some server somewhere whereas my take on CryptoCat is that it facilitates secure non-persistent multiparty chat.

Oh, and the two factor authentication is interesting for login is interesting.

How is this any different from Cryptocat?

    I had a chance to try out crypho a couple of weeks ago at a demo they
    put on at noisebridge.  I have some concerns about it, namely the
    delivery of crypto code over javascript without any sort of
    verification
    of it's authenticity (via browser plugin, etc.), since this point has
    already been discussed to death on this list however, I do not wish to
    re-open that debate.
    I managed to find a couple of javascript injection attacks in the beta
    already, though the developer assures me that they are working on
    fixing
    all the bugs right now, still the lack of attention to basic web
    security at such an early stage is concerning.
    That aside it seems okay, though I have some worries about side
    channel
    attacks and the fact that it hasn't been peer reviewed as far as I can
    tell yet.
    It does seem like an interesting project though, with some smart
    people
    behind it. I am looking forward to seeing the code once they open
    source it.
