2. Encryption utilities

Encryption scrambles data in such a way that only a person (or computer) with the correct software key can read it. For a full explanation we have a page on it here.


Much of the data that we send via the internet is encrypted by software already built into the browser. Pages displaying "HTTPS" in their URL show that data can be sent safely and securely without having to take any additional measures.

But not all data is sent - some of it is just stored. Many organisations need to ensure that data they store is secure and cannot be accessed or viewed by unauthorised people. For example, under the Data Protection Act, all personal data about customers and staff must be stored in a secure manner.

An encryption utility can be used to secure data. The file is selected, a password created and the encryption utility encrypts the data within that file. In order to decrypt the data, the correct password must be entered before it will be unencrypted and presented to you in its original format.
