Encryption is the process of scrambling data and information into a form which can only be decoded by the parties who have the keys. This can be accomplished using a variety of mathematical models, and is used to secure information and data in the daily lives of both companies and consumers.
Modern encryption algorithms are vital to ensure the security of digital information stored on computers or transmitted via networks like the internet. It also offers security measures such as authentication (verifying the origin of the message) as well as integrity (ensuring it’s not altered) and anti-repudiation.
Encryption works by translating plaintext that is human-readable into an encrypted format known as ciphertext, by utilizing mathematical models called algorithms. The ciphertext is only look here readable by a decryption key, which is a secret password, or a sequence of numbers that the sender and recipient have agreed upon. The stronger the cryptographic key is, the more difficult for unauthorized third parties to decipher it using brute force methods like trying every possible string of characters.
Many privacy and security regulations require the use of strong encryption to help ensure that personal information stays private and safe. Many individuals and businesses utilize encryption to safeguard their folders, files and entire computers with software programs such as 7-Zip or CertainSafe and they can also secure their entire hard drive in the cloud with virtual private networks. Furthermore, a number of businesses offer a variety of encryption options that offer multiple types of encryption for the most secure protection.
