    Every modern computer comes with tools for encryption of data, making it unreadable to anyone without the proper key. What exactly is encryption, and how does it function? This article bigtechinfo.com/the-most-effective-free-antivirus-apps-for-android-in-2022/ explains how encryption safeguards sensitive information from hackers.

    Data encryption is the process of changing readable information into a coded form that can only be deciphered by using the proper password by authorized users. It is a vital element of cyber security, which ensures privacy of data and protects sensitive information out of access of anyone who is not authorized to use it.

    A common form uses mathematical models that are cryptographic in order to convert the original information into a jumbled set of characters (also known as ciphertext). Encryption algorithms «scrambles» individual bits in a random manner to ensure that it takes an enormous amount of computing power to determine the key and then convert back to plaintext.

    For example, if you use the most common form of encryption known as AES (Advanced Encryption Standard) for your digital files, each one of the zeros and ones that make up it is scrambled 10 times in an uni-random pattern. It would take a computer several hours to change all the numbers into the proper order without a key.

    The encryption process can also be used to prevent data leaks and ransomware. Hackers who gain access to encrypted data are unable to read the data and cannot threaten the company, or the person involved, with the threat to release the stolen information onto the dark web. Encryption also protects backup systems from hackers since they are unable to access the data in its original format.
