What is Encryption in Computer Software?

Modern computers have tools to secure data, making it unreadable for anyone who does not have the correct key. What is encryption and how does it function? This article explains the basics of encryption and how it can help secure sensitive information from hackers.

In simple terms, data encryption converts the information that is readable into encrypted ciphertext that can only be deciphered by authorized users with the appropriate password. It is an essential element of cyber-security which guarantees the security of data and protects sensitive information from unauthorized users.

The most common type of encryption employs cryptographic mathematical models to transform the original data into a fragmented set of characters that isn’t easily read (known as”ciphertext”). Encryption algorithms “scramble” bits of data in a random manner, so that even with a huge computing power it would take a long time to try and determine the key needed to convert back to plain text.

For instance, if you make use of the most widely used type of encryption, referred to AES (Advanced Encryption Standard) for your digital files, each one of the zeros and ones that comprise it gets scrambled ten times to form an uni-random pattern. Without the correct key to decipher it, a computer would have to run for an extremely long time in order to organize them all into the proper order.

Also, encryption is used to prevent data leaks and ransomware. Hackers who gain access to encrypted data can’t read the information and aren’t able to blackmail the company or the individual involved with the threat to release the stolen information to the dark web. Additionally, encryption safeguards backup systems from hackers since they can’t access the information features of M&A software in its original format.
