What is Encryption in Computer Software?

Every modern computer has tools for encrypting data to make it unreadable to anyone without the proper key. What is encryption and how does it work? This article will explain the basics of encryption and how it helps secure sensitive information from hackers.

In simple words, data encryption converts readable information into coded encrypted ciphertext that can only be deciphered by authorized users who have the appropriate password. It is an important component of cyber-security that provides the security of data and protects sensitive information from unauthorised users.

A common form of encryption makes use of cryptographic mathematical models to turn reference the original information into a fragmented set of characters that isn’t readable (known as ciphertext). Encryption algorithms “scramble” individual bits in a random manner, so that even with enormous computing power, it could take a very long time to try and 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 that means that each of the zeros and ones within the file is scrambled 10 times in a semi-random pattern. It will take computers an extended time to reorder all the numbers in the proper order, without the key.

Also, encryption is used to stop data leaks and ransomware. Hackers who steal encrypted information can’t read the information, and cannot blackmail the company, or the person who is involved with the threat to release the stolen information onto the dark web. Encryption also protects backup systems against hackers, as they are unable to access the data in its original format.
