What is Encryption in Computer Software?

Every modern computer has tools for encryption of data, making it unreadable to anyone without a key. What is encryption and how does it work? This article will explain how encryption protects sensitive information from hackers.

In simplest terms, data encryption converts data that is readable into coded encryption that can be deciphered by authorized users with the right password. It is a crucial element of cyber-security that provides security of data and keeps sensitive information away from any unauthorised users.

A common form of encryption employs cryptographic mathematical models to transform the original data into a fragmented set of characters that aren’t readable (known as ciphertext). The encryption algorithms “scramble” individual bits in a random fashion, such that even with huge computing power, it could take a very long time to try and discover the key that will convert back to plain text.

If you’re using AES (Advanced Encryption Standard), the most common encryption method for your digital files every one of the zeros and ones within the file is scrambled ten times in a semi-random pattern. It would take a computer some time to reorder all the numbers in the correct order without the key.

Encryption also serves to prevent the leak of information and attacks by ransomware. If a hacker steals encrypted data, they are unable to access it and will be in a position to not blackmail the business or board computer protection software anyone else involved in the possibility of releasing stolen data on the dark web. Additionally, encryption safeguards backup systems from hackers as they can’t access the information in its original format.
