PRNGs are a key component of cryptographic softwareįor the same reason that you don’t use the same password on more than one website, so that one cracked password doesn’t open up your whole online life, Cryptocat generates new keys every time you chat to someone. One of these flaws was found in the heart of Cryptocat’s PRNG (pseudo-random number generator). It turned out that the Cryptocat code had for some time contained a number of cryptographic flaws that made it measurably less secure than its users might reasonably have assumed. The software enjoyed a surge in popularity as a result, which made last week’s Fourth-of-July vulnerability announcement all the more worrying. I hope you guys are encouraged to try it too.We recently wrote about a security advisory from Cryptocat, an open-source web-based secure messaging project.Ĭryptocat’s hacktivist credibility was cemented in 2012 when its Canadian developer, Nadim Kobeissi, was stopped at the US border and interviewed about his Cryptocat-related programming activities. It uses XMPP and OTR as protocols.Ĭryptocat is safe because it creates two keys, one that it sends to our interlocutor and the other encrypted that will be used to decrypt his messages, that is, totally private.Īt the interoperability level, the fun thing about this application is that it works in browsers as a complement for Safari, Chrome / mium, Firefox and it will soon be available as a mobile application and I must tell you that its design is great (XD).Īt the moment I am learning to use it although it does not have great difficulty and what I would need in any case is a good number of users, otherwise it is fine I doubt that it will surpass WhatsApp but at least I plan to use it to annoy my friends and to have something to prove since it not only defends my privacy but is also free (did you think I was going to review something that was not?) is not the case of Cryptocat, which is an alternative to Gtalk, WhatsApp, Facebook chat, MSN and everything else. In the long run I have seen a thousand things when it comes to chatting, really, but all the options have big drawbacks, and one of them is that they either do not have mobile applications or the applications are simply ugly, complicated or simply do not attract attention. Now, I have also seen alternatives to WhatsApp, the renowned archi « bbpin killer»Which, not only killed the blackberry msn but also is extremely careless with our data and conversations, you know, any moron who has the right program (which I am not going to mention) and is connected to the same Wi-Fi network can steal all of you your conversations and data transferred via whatsapp, how are you? about DuckDuckGo I can't speak because I've only been using it for a few days instead of google and it works for me. I am not someone obsessed with privacy, that is something that many who know me know, but I do have it in mind enough and I am very aware of everything I say and use on the network because, let's face it, neither google nor facebook nor anyone really takes care of our data, of course, we have alternatives like DuckDuckGo y Diaspora but many do not like these alternatives, and to be honest, D * has become somewhat bland and they gave up to make way for a social network / meme app.
