What is Encryption in Computer Software?

Every modern computer includes tools to encrypt data in order to make it unreadable by unauthorized parties without a key. What is encryption and how does it work? This article explains how encryption safeguards sensitive information from hackers.

In simplest words, data encryption converts data that is readable into coded encrypted text that can only be deciphered only by authorized users with the right password. It is a vital component of cyber-security, which ensures data security and keeps sensitive data from any unauthorised users.

An encryption method that is commonly used makes use of cryptographic mathematical models to turn the original information into a confusing collection of characters that isn’t easily accessible (known as”ciphertext”). The encryption algorithm “scrambles” individual bits in a random manner so that it would take an enormous amount of computing power to figure out the key and then convert it back to plaintext.

If you’re using AES (Advanced Encryption Standard) which is the most commonly used encryption method, on your digital files and files, then all the ones and 0s in the file is smashed 10 times in a semi-random pattern. It would take computers a long time to rearrange all the numbers into the proper order without a key.

It also helps to stop the leak of information and attacks by ransomware. If a hacker steals encrypted data, they will be unable to read it and are in a position to not blackmail the business or individuals involved with the risk of releasing the stolen information to the dark web. Encryption also protects backup systems from hackers since they can’t access the data in its original format.
