The biggest advantage of encrypting your files is the knowledge that your data will be safe if your computer is stolen. Its entire purpose is to keep files hidden and safe. If you have files that you don’t want (or can’t afford) anyone else to see, then you have a use for file encryption. The files are safe as long as they are kept in the encrypted area. In this manual we’ll be talking about local file encryption – that is, encrypting files on a hard drive (or encrypting the entire hard drive more on that later). If you use instant messaging programs it is possible to create an encryption tunnel to ensure that only you and the person you’re talking to can see the messages. Whenever you buy something online and make a transaction, all your details are heavily encrypted until they reach the other end, making sure that no third party could be listening in. The data is unintelligible, undetectable, unreadable and irretrievable unless a key is used to reverse the encryption, or decrypt, the data.Įncryption is used all the time, often without you even realising it. If only you’d encrypted your data.Įncryption is the process of protecting data by using an algorithm to scramble it. The world shrinks around you as you realise the enormity of what has just happened. Who knows where they could end up and who could see them? Who knows how that information could be exploited? What am I going to do? I’ve got them all backed up, but that’s not the problem here. My personal details, and the details of all my friends and family. It was an old laptop, faithful but due for retirement. “I’m not getting that back.” But it’s not that bad. Maybe I just put it down by the chair so that it was out of the way. It takes a moment to sink in.įirst comes the initial shock, then the disbelief. You left it there for just a second and there were plenty of people around, but you came back and it was gone. If you use instant messaging programs it is possible to create an encryption tunnel to ensure that only you and the person you're talking to can see the messages. Not sure how to start?

To really keep your data safe, you need to encrypt it.
