Every modern computer includes tools to encrypt data in order to make it unreadable by unauthorized parties without the proper key. What is encryption and how does it work? This article will explain the basics of encryption and how it helps protect sensitive information from hackers.
In simplest terms, data encryption converts data that is readable into coded ciphertext that can only be deciphered by authorized individuals with the appropriate password. It is a crucial element of cyber security that ensures security of data and keeps confidential information from the hands of unauthorised users.
The most common type of encryption uses mathematical models that are cryptographic to transform the original data into a jumbled set of characters (also called ciphertext). The encryption algorithm “scrambles” individual bits in a random manner so that it would take an enormous amount of computing power to find the key and convert back to plaintext.
If you’re using AES (Advanced Encryption Standard) which is the most widely used encryption method, on your digital files and files, then all the ones and zeros in the file are scrambled 10 times in a semi random pattern. Without the right key to understand it, the computer would need to run for a long time in order to arrange them into the correct form.
It also helps to stop data leaks and ransomware attacks. Hackers who steal encrypted information can’t read the information, and cannot blackmail the company, or the person who is involved with threats to release the stolen data to the dark web. Furthermore, encryption protects backup systems from hackers because they cannot access the data in its original format.
