Word History

Etymology

borrowed from New Latin cryptographia, from crypto- crypto- + -graphia -graphy

Note: New Latin cryptographia was perhaps first used by the Limburg-born philologist Erycius Puteanus (Eric de Put, Eric van den Putte, 1574-1646) in "Cryptographia epistolica, sive de clandestina scriptione," an addendum to his Epistolarum reliquiae centuria V (Leuven/Louvain, 1612). An apparently more widely circulated work using the word was Cryptomenytices et cryptographiae libri IX (Lüneburg, 1624) by Gustavus Selenus, pseudonym of Augustus the Younger, Duke of Brunswick-Lüneburg (1579-1666).

First Known Use

1646, in the meaning defined at sense 1

释义	cryptography noun cryp·tog·ra·phy krip-ˈtä-grə-fē 1 : secret writing 2 : the enciphering and deciphering of messages in secret code or cipher also : the computerized encoding and decoding of information 3 : cryptanalysis Did you know? For a word having to do with secrets, cryptography has a surprisingly transparent origin. The word comes from Greek kryptós, meaning "hidden" or "secret," and graphein, meaning "to write." Besides the familiar related words of the same origin, such as cryptic, there is krypton, the name of a colorless gaseous element used especially in some fluorescent lamps and photography flashes. The name was chosen because the gas is rare and hard to find. Example Sentences Companies often use cryptography to protect private information.
