What is Encryption in Computer Software?

Every modern computer has a tool for encryption of data, making it impossible for anyone without a key. But what exactly is encryption, and how does it work? This article explains how encryption can protect sensitive information from snoopers.

In simplest terms, data encryption converts textual information into ciphertext that can only be deciphered only by authorized users with the correct password. It is a vital element of cyber security that guarantees the privacy of data and keeps confidential information from the hands of unauthorized users.

A common form of encryption uses cryptographic mathematical models to turn the original information into a fragmented set of characters that isn’t easily accessible (known as”ciphertext”). Encryption algorithms “scramble” bits of information in a random way, meaning that even with enormous computing power, it would take a long time to figure out the key to convert back to plain text.

If you use AES (Advanced Encryption Standard) which is the most widely used encryption method, for your digital files and files, then all the zeros and ones within the file is smashed 10 times in a semi-random pattern. It will take computers a long time to rearrange all the numbers into the proper order without a key.

The encryption process also helps prevent data leaks and ransomware attacks. Hackers who steal encrypted information are unable to read the data and cannot blackmail the company, or the individual involved by threatening to release the stolen information to the dark web. Furthermore, encryption protects backup systems from hackers because they aren’t able access the data in its original format.
