Modern computers have tools for encrypting data that makes it inaccessible to anyone without the right key. What is encryption and how does it work? This article explains how encryption protects sensitive information from snoopers.
In simple terms, data encryption transforms readable information into coded encrypted ciphertext that can only be deciphered by authorized users with the correct password. It is a vital component of cyber-security which guarantees the security of data as well as keeping confidential information from being accessed by any unauthorised users.
An encryption method that is commonly used makes use of cryptographic mathematical models to transform the original data into a confusing collection of characters that aren’t read (known as»ciphertext»). The encryption algorithm «scrambles» individual bits in a random manner so that it requires a huge amount of computing power to determine the key, and then convert it to plaintext.
If you’re using AES (Advanced Encryption Standard), the most common encryption method for your digital files every one of the ones and zeros in the file is smashed 10 times in a semi random pattern. It would take computers an extended time to reorder all the numbers in the proper order without a key.
Encryption can also help prevent ransomware attacks and leaks of information. If a hacker steals encrypted data, they are unable to read it and will be in a position to not blackmail the business or individuals involved with the possibility of releasing stolen data to the dark web. It also protects backup systems from hackers since they are unable to access the data in its original format.
