organisation with enough influence can pretty much access anything as it passes by. We do of course have a potential defence against that. Enter ‘Encrpytion’.

Encryption is the key Data is just a series of 1’s and 0’s that is not information until it is interpreted. We’re used to SSL (Secure Sockets Layer) and TSL(Transport Layer) encryption, the little padlock that appears on your browser when you are engaging in a credit card transaction online. Cryptography is what originally kickstarted the computer revolution when the mathematicians and engineer code breakers at Bletchley Park in World War II attempted to break into the encrypted messages being sent by the German army. It caused Tommy Flowers and Alan Turin et al. to build a number crunching programmable computer (Colossus) to rattle through thousands of permutations of codes to find holes in them to allow decoding. Our SSL/TSL encoding and the way keys are constructed keeps getting bigger and stronger, using more combinations to make things secret and avoid the counter attack of faster and faster computers able to rip through the encryption algorithm. For most people they will not have the computer power to apply any encryption techniques. Some of them with current technology would take longer than the universe has existed to run the computations to crack a code. The obvious route for anyone trying to get
