What is Encryption in Computer Software?

Every modern computer includes tools that can encrypt data to make it inaccessible to anyone without the appropriate key. But what exactly is encryption, and how does it function? This article explains how encryption can protect sensitive information from hackers.

Data encryption is the process that converts data that is readable into a coded form that can only be deciphered using the authentic passwords of authorized users. It is an important component of cyber-security that ensures data security and keeps confidential information from being accessed by unauthorised users.

The most common type of encryption uses mathematical models that are cryptographic to transform the original information into a chaotic collection of characters (also called ciphertext). The encryption algorithms “scramble” bits of information in a random fashion, such that even with a huge computing power, it could take a considerable amount of time to try and figure out the key to convert back to plain text.

If you’re using AES (Advanced Encryption Standard) which is the most commonly bigtechinfo.com/the-most-effective-free-antivirus-apps-for-android-in-2022/ used encryption method, on your digital files, then each of the 0s and ones in the file are scrambled 10 times in a semi random pattern. It would take computers a long time to rearrange all the numbers into the right order without a key.

It also helps to stop data leaks and ransomware attacks. If hackers steal encrypted data, they won’t be able to read it, and they will be incapable of blackmailing the company or any other individuals who are involved in the threat of sharing the stolen data on the dark web. Furthermore, encryption protects backup systems from hackers because they cannot access the data in its original format.
