Data encryption is a potent security measure that encrypts sensitive data into unreadable gibberish which only the intended recipient will be able to decode it. It is a crucial aspect of digital transformation because it protects the security of information stored on or transmitted via networks or computer systems like the Internet. It offers integrity and authentication and ensures that data is not altered or tampered when it is stored or transmitted.
The process of encrypting data involves converting the original information into a format that can only be read by the person receiving it using a password or key. In the majority of cases, the recipient can then convert the encrypted text back into its original form. Modern encryption techniques use bigtechinfo.com/secureline-vpn-review algorithms to scramble the original data into the ciphertext. There are a variety of algorithms and methods used to accomplish this which include transposition and substitution techniques. The Caesar cipher is an early example of a substitution cipher. Each letter is replaced with another one at a specific number of positions along the alphabet.
The use of encryption can ensure compliance with regulations set by different institutions or standard bodies including the Fair Credit Reporting Act (FCRA) and other consumer protection laws. It is also an essential security measure to protect sensitive company, client or patient information from cyberattacks. Retailers must, for example protect credit card information and shipping details when they transfer data between networks or between systems. The encryption process can also protect data at rest on computers, USB devices and other hardware from physical or virtual theft by hackers.
