The story of the word

The verb is much younger than it looks. Cryptography and cryptogram were centuries old before anyone thought to encrypt anything, which took twentieth-century signals work to make necessary. A κρύπτη was a vault or covered passage, so a church crypt and an encryption key are the same Greek adjective, and the en- on the front is Latin arriving by way of French.
