The coding of sensitive information for transfer online or otherwise electronically. One may encrypt data to prevent anyone other than the intended recipient from accessing it. For example, if one buys a product online and enters credit card information into an electronic form, that information is usually encrypted so hackers and potential identity thieves cannot use it for illicit purposes.
