Every modern computer comes with tools for encrypting data to make it inaccessible to anyone without the appropriate key. What exactly is encryption, and how does it work? This article explains how encryption protects sensitive information from hackers.
In simplest terms, data encryption converts readable information into coded encryption that can be deciphered by authorized users who have the right password. It is a vital element of cyber security that guarantees privacy of data and protects confidential information from the fingers of users who are not authorized.
The most common type of encryption uses mathematical models that are cryptographic to transform the original information into a jumbled set of characters (also known as ciphertext). Encryption algorithms “scramble” individual bits in a random fashion, such that even with huge computing power it would take a very long time to figure out the key to convert back to plain text.
For instance, if you employ the most commonly used form of encryption referred to as AES (Advanced Encryption Standard) on your digital files, each one of the ones and zeros which make up the file is scrambled ten times to form an uni-random pattern. It will take a computer several hours to change all the numbers into the proper order without a key.
The encryption process also helps prevent the leak deal room software of information and attacks by ransomware. Hackers who take encrypted data can’t read the information and cannot threaten the company, or the individual responsible, with the threat to release the stolen data to the dark web. Additionally, encryption protects backup systems from hackers since they cannot access the data in its original form.
