![]() In this case you’retruly dependent on their good behaviour.* This works fine if the server really is trustworthy, but it’s huge problem if the server is ever compromised - or forced to engage in Man-In-The-Middle attacks by a nosy government.Īn even worse variant of this attack comes from services that actually store your secret keys for you. Clients depend fundamentally on a central directly server to obtain their encryption keys. In this scenario - known as a Man in the Middle(MITM)attack - all the encryption in the world won’t help you.Īnd this is where most ‘end-to-end’ commercial services (like Skype and iMessage) seem to fall down. The problem here is simple: if I can compromise such a service, then I can convince you to use my encryption key instead of your intended recipient’s. The real challenge turns out to be distributing users’ encryption keyssecurely, that is, without relying on a trusted, central service. That’s because actually encrypting stuff is not the interesting part. However - and this is a critical point - ‘end-to-end encryption’ is rapidly becoming the most useless term in the security lexicon. This has even gotten Skype and Blackberry into a bit of hot water with foreign governments. In fact, these days almost everyone advertises some form of ‘ end-to-end encryption‘ for your data. ![]() First, the apps we’ll talk about here are hardly the only apps that use encryption. A couple of notes…īefore we get to the details, a few stipulations. In no particular order, these are Cryptocat, Silent Circle, RedPhone and Wickr. To take a crack at answering these questions, I’m going to look at four apps that seem to be getting a lot of press in this area. How solid are they? What makes them different/better than what came before? And most importantly: should you trust them with your life? Given what’s at stake, it seems worthwhile to sit down and look carefully at some of these new tools. At the same time, I worry that too much hype can be a bad thing - and could even get people killed. After all, I’ve spent a lot of my professional life working on crypto, and it’s nice to imagine that people are actually going to start usingit. This is exciting stuff, and I want to believe. Even if a CryptoKitty is a dame or sire in one breeding pair, it can have the opposite role in a future breeding pair.It seems like these days I can’t eat breakfast without reading about some new encryption app that will supposedly revolutionise our communications - while making tyrannical regimes fall like cheap confetti. The owner of the “dame” CryptoKitty receives the new offspring kitten. One CryptoKitty in the transaction is the “dame” and the other is the “sire.” The owners decide which cat is which. CryptoKitties don’t have biological sexes, so any two CryptoKitties can function as a breeding pair if their owners agree. You can “breed” two different CryptoKitties together to get a new CryptoKitty. All new kitties will be produced through breeding after that point. In November 2018, a year after the game launched in November 2017, the last “generation 0” cat will be born. Since then, a new “generation 0” cat has been born every fifteen minutes. The first CryptoKitty-the “ genesis cat“-was born on December 2, 2017. RELATED: What is Ethereum, and What Are Smart Contracts? CryptoKitties Reproduce Through Smart Contracts Here are the $110,707 cat’s children. They can also be bred with another CryptoKitty to create a new kitty. These CryptoKitties can be traded, sold, and purchased like any other digital asset. Some CryptoKitties have “mewtations,” which are rare cattributes. These features come together to give each CryptoKitty a unique look. ![]() Each CryptoKitty has a combination of “cattributes” that make it unique.
