mindmap root((CRYPT)) crypt 1、 A room completely or partly underground, especially under the main floor of a church.
2、 A room or area in a large aboveground tomb.
🌱His old nightmare was of being locked in a crypt with corpses as his only companions. 🌳Hidden under the main floor of a great church is often a large room, often with a tomb as its centerpiece. Many major European churches were built over the remains of a saint—the Vatican's great St. Peter's Basilica is an example—and instead of having the coffin buried, it was often given its spacious room below ground level. In a large aboveground tomb, or mausoleum, there may be several small chambers for individual coffins, also called crypts; when the comic book Tales from the Crypt made its first appearance in 1950, it was this meaning that the authors were referring to. encrypt 1、 To convert into cipher.
2、 To convert a message into code.
🌱Messages on the group's Web site are encrypted in code words to keep law-enforcement agents from understanding them. 🌳Codes aren't always in another language; people have always been able to communicate in ways that conceal their real meaning. In countries ruled by dictators, novelists and playwrights have sometimes managed to encrypt their messages, conveying political ideas to their audiences so that the authorities never notice. But encryption today usually refers to a complex procedure performed on electronic text to make sure the wrong people—whether a nation's enemies or a business competitor （most businesses use encryption today）—can't read it. And sensitive data that merely resides on a company's own computers is often encrypted as well. cryptic 1、 Mysterious; puzzlingly short.
2、 Acting to hide or conceal.
🌱From across the room, Louisa threw Philip a cryptic look, and he puzzled over what she was trying to tell him. 🌳Until the writing on the famous Rosetta Stone was finally translated in the early 19th century, Egyptian hieroglyphic writing was entirely cryptic, its meaning hidden from the modern world. In the same way, a cryptic comment is one whose meaning is unclear, and a cryptic note may leave you wondering. Cryptic coloring among plants and animals acts like camouflage; so, for example, some moths that are tasty to blue jays are cryptically colored to look like bugs that jays won't touch. cryptography 1、 Secret writing.
2、 The encoding and decoding of messages.
🌱As a graduate student in mathematics, she never dreamed she would end up working in cryptography for the Defense Department. 🌳During World War II, cryptography became an extremely complex science for both the Allied and Axis powers. The Allies managed to secretly crack the code produced by the Nazis' Enigma machine, and thereby may have shortened the war by two years. The Axis cryptographers, on the other hand, never managed to crack the Americans' ultimate code—the spoken languages of the Navajo and other American Indians. In the age of computers, cryptography has become almost unbelievably complex; it's widely used in peacetime in such areas as banking telecommunications.
