If you are looking for ways to secure your privacy online, you should know by now that the first step is to use encryption for everything. Yet, cryptography is not exactly the most popular or easily digestible of sciences. It could be hard to make sense of all the protocol and algorithm names flying around.
Google announced last month the first ever collision generated in the SHA-1 cryptographic hashing algorithm. Or to paraphrase it – SHA-1 is not secure anymore. Truth be told, theoretical flaws in the algorithm were known for a long time. And this is why Secure Group has already moved on to SHA-2 for the implementation of Off-the-Record (OTR) encryption in our proprietary chat client, Secure Chat. But what does SHA-1’s demise mean for cryptography and security?
How do you make sure you are not a target of a man-in-the-middle (MitM) attack when using an instant messaging app? Encryption can secure the content of a conversation from eavesdroppers, but what if someone has hacked the account of the person you want to talk to and is impersonating them? The off-the-record (OTR) encryption protocol used by Secure Chat solves this problem by providing mutual identification through the Socialist Millionaire Protocol.
What could be very convenient and extremely dangerous at the same time? A chat that's tapped. And what's the best way to counter this danger? By using OTR encryption for chat! Yes, today we're going to focus on how to protect instant messaging from any kind of surveillance.
