Modern computers are equipped with tools for encrypting data which makes it unreadable to anyone without the right key. What is encryption and how does it work? This article will explain the basics of encryption and how it can be used to secure sensitive information from hackers.
Data encryption is the process of converting data that is readable into coded text that can only be deciphered with the authentic passwords of authorized users. It is a critical component of cyber security that ensures security of data and keeps sensitive data out of the access of anyone who is not authorized to use it.
The most common type of encryption uses mathematical models that are cryptographic to transform the original information into a jumbled assortment of characters (also called ciphertext). The encryption algorithm “scrambles” individual bits in a random manner so that it requires an immense amount of computing power to identify the key and convert back to plaintext.
If you’re using AES (Advanced Encryption Standard) which is the most popular encryption method, on your digital files every one of the zeros additional info and ones within the file is smashed 10 times in a semi random pattern. Without the correct key to decipher it, the computer would need to run for a long time in order to arrange them in the right order.
It is also used to protect against data leaks and ransomware. If hackers steal encrypted data, they can’t read it and are incapable of blackmailing the company or the individuals involved in the threat of sharing the stolen information to the dark web. Additionally, encryption protects backup systems from hackers as they aren’t able to access the data in its original form.
