Every modern computer has a tool for encrypting data to make it impossible for anyone without a valid key. What exactly is encryption, and how does it function? This article will explain how encryption protects sensitive information from hackers.

Data encryption is the process of changing readable information into a coded form that can only be deciphered by using the authentic passwords of authorized users. It is an essential element of cyber security that guarantees privacy of data and protects sensitive data out of the hands of unauthorized users.

A typical form employs mathematical models that are cryptographic in order to convert the original information into a jumbled collection of characters (also called ciphertext). The encryption algorithm “scrambles” individual bits of data randomly, to ensure that it takes an immense amount of computing power to figure out the key and then convert it back to plaintext.

For instance, if employ the most popular type of encryption referred to as AES (Advanced Encryption Standard) for your digital files, every one of the ones and zeros which make up the file is scrambled ten times, creating an uni-random pattern. Without the correct key to understand it, the computer will have to run for a very long time to sort them into the proper order.

Also, encryption is employed to prevent data leaks and ransomware. If hackers steal encrypted data, they are unable to read it, and they will be not able to blackmail the company or individuals involved with the risk of releasing the stolen information to the dark web. It also safeguards backup systems from hackers, as they are unable to access the data in its original format.
