What is Encryption in Computer Software?
Every modern computer comes with tools that can encrypt data to make it inaccessible to anyone without a valid key. What is encryption and how does it function? This article will explain the basics of encryption and how it helps secure sensitive information from hackers.
In simplest words, data encryption converts data that is readable into coded encrypted ciphertext that can only be deciphered only by authorized users with the appropriate password. It is an important component of cyber-security, which ensures the security of data and protects sensitive information from non-authorized users.
A typical form employs mathematical models that are cryptographic to transform the original data into a jumbled set of characters (also known as ciphertext). The encryption algorithm “scrambles” individual bits in a random manner so that it would take an immense amount of computing power to figure out the key, and then convert it to plaintext.
If you use AES (Advanced Encryption Standard) which is the most commonly used encryption method, for your digital files that means that each of the 0s and ones in the file is smashed 10 times in a semi random pattern. It would take a computer some time to reorder all the numbers into the correct order without the key.
It also helps to stop information leaks and ransomware attacks. If hackers steal encrypted data, they will be unable to read it and will be not able to blackmail the company or individuals involved with the possibility of releasing stolen data on the dark web. The encryption also protects backup systems from hackers, as they are unable to access the data in its original format.
