Data encryption is a potent cybersecurity measure that scrambles sensitive information into a non-readable language, so only the intended recipient can decode it. It is a vital aspect of digital transformation, as it ensures the security of the data stored on computers or networks like the Internet. It also provides authenticity and integrity, ensuring that the information isn’t modified or tampered with in the process of storage or transmission.

Encrypting data is the process of changing original information into the format that can only by read by the person receiving it using keys or passwords. In the majority of instances, a user can translate the ciphertext into its original format. Modern encryption techniques use algorithms to scramble the original data into the ciphertext. This is accomplished using various methods and algorithms, such as transposition and substitution techniques. The Caesar cipher is named after Caesar, the Roman Emperor Julius Caesar, is an early example of a cipher for substitution that is where each letter is replaced by one of a set number of times along the alphabet (e.g., «E» is transformed into «Y»).

The use of encryption is frequently required to uphold compliance with the regulations set forth by various organizations or standards bodies, such as the Fair Credit Reporting Act and other consumer protection laws. It is also a vital security measure to safeguard sensitive company, client or patient information from cyberattacks. Retailers, for instance need to safeguard their customers’ credit card information and shipping details when transferring it between systems or networks. The process of encryption can safeguard data stored on computers, USB devices and other hardware from theft via physical or digital means by hackers.
