Modern computers include tools to encrypt data and make it unreadable for anyone who does not have the correct 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 simple words, data encryption converts textual information into encrypted ciphertext that can only be deciphered by authorized individuals with the appropriate password. It is a vital component of cyber-security that ensures security of data and keeps sensitive data from unauthorised users.
The most common type of encryption makes use of cryptographic mathematical models to transform the original data into a confusing collection of characters that isn’t accessible (known as ciphertext). The encryption algorithms “scramble” bits of information in a randomized fashion so that even with huge computing power, it would take a lot of time to find the key to convert back to plain text.
For instance, if you employ the most commonly used form of encryption, referred to AES (Advanced Encryption Standard) for your digital files, each one of the ones and zeros that comprise it is scrambled 10 times in an uni-random pattern. Without the correct key to decipher it computers would have to run for a long time to organize them all to the correct order.
The encryption process can also be used to protect against data leaks and ransomware. If hackers steal encrypted data, they won’t be able to read it and will be unable to blackmail the company or individuals involved with the risk of releasing the stolen information to the dark web. Encryption also safeguards backup systems from hackers, as they are unable to access the data in its original format.
