What is Encryption in Computer Software?

Every modern computer comes with tools to encrypt data in order to make it inaccessible to anyone without a valid key. But what is encryption exactly and how does it work? This article will explain how encryption protects sensitive information from snoopers.

In simplest terms, data encryption transforms textual information into encrypted text that can only be deciphered only by authorized users with the correct password. It is an important component of cyber-security, which ensures the security of data and protects confidential information from being accessed by unauthorised users.

A common type employs mathematical models that are cryptographic to convert the original data into a jumbled assortment of characters (also called ciphertext). The encryption algorithms “scramble” bits of information in a random way, meaning that even with enormous computing power, it would take a long time to try and determine the key needed to convert back to plain text.

For instance, if use the most common form of encryption referred to as AES (Advanced Encryption Standard) on your digital files, each one of the ones and zeros that comprise it is scrambled ten times in an uni-random pattern. It would take computers a long time to rearrange all the numbers in the right order without a key.

Also, encryption is employed to prevent data leaks and ransomware. If hackers steal encrypted data, they will be unable to read it, and they will be incapable of blackmailing the company or any other individuals who are involved in the threat of releasing the stolen data on the dark web. Also, encryption safeguards backup systems from hackers since they can’t access the data in its original format.
