Encryption Explained

Today, I will discuss phone encryption, what it is and the different kinds on the marketplace.

Encryption is essentially taking a computer algorithm and implementing it to a bit of information and rendering it unreadable to another party. In essence the one person who can read this info is the person that has the key to decrypt it. In the event that you had info on your hard disk that was sensitive (excluding fiscal documents etc) then you can encrypt it so nobody else can read it. This is particularly helpful when the laptop you store your own information on is stolen.

Which are the different kinds?

There are loads of different forms of encryption and one you use will depend on what you would like to encrypt. For instance you can use various kinds of encryption based on if you would like to encrypt transmissions, files or databases / folders. I am going to focus on folders / files since that is what the majority of people will be searching for – creating documents unreadable to third parties.

That is where I will present you to two of the most well-known parts of encryption software, TrueCrypt and BitLocker both of which operate on Windows. Truecrypt is available source whilst Bit Locker is proprietary software from Microsoft. Both may encrypt and decrypt a hard disk and both are almost indestructible (in time of printing!!). TrueCrypt is not difficult to prepare and doesn’t require repartitioning of your hard disk, whereas Bit Locker does. Bit Locker takes a 1.5 GB partition to be installed prior to installing the operating system. Otherwise you’ll need to repartition your hard disk and then restore Windows from a backup.

So what would be the benefits and pitfalls of phone encryption?


1. Data is secure as nobody else may read it without the decryption key.

2. Once setup it requires little if any user input.
