IPA guide

Encryption is the process of translating something into a code, so that data is protected, hidden, or concealed. Encryption makes it difficult for hackers to steal people's credit card numbers.

If there's information worth stealing, encryption is used to protect it — especially when it comes to computer or electronic data that holds financial, private, or dangerous material. Governments use encryption to hide classified information, and banks use it to protect their customers' money and other data. Crypt- has been used to mean "secret or hidden" since the 1700s, and it comes from a Greek root, kryptos, "hidden or concealed."
