A crypt (from Greek κρύπτη (kryptē) crypta "vault") is a stone chamber beneath the floor of a church or other building. It typically contains coffins , sarcophagi , or religious relics . Originally, crypts were typically found below the main apse of a church, such as at the Abbey of Saint-Germain en Auxerre , but were later located ...
Before the modern era, cryptography focused on message confidentiality (i.e., encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the key needed for decryption of that message).
A simple illustration of public-key cryptography, one of the most widely used forms of encryption. In cryptography, encryption (more specifically, encoding) is the process of transforming information in a way that, ideally, only authorized parties can decode.
Cryptids are animals or other beings that cryptozoologists believe may exist somewhere in the wild, but whose present existence is disputed or unsubstantiated by science. ...
Reconstruction of the appearance of cyclometer, a device used to break the encryption of the Enigma machine.Based on sketches in Marian Rejewski's memoirs.. Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. [1]
The term is sometimes used to describe a crypt beneath a church, used for burial purposes. For example, there is a 14th-century undercroft or crypt extant at Muchalls Castle in Aberdeenshire in Scotland, even though the original chapel above it was destroyed in an act of war in 1746.

An unpredictable (typically large and random) number is used to begin generation of an acceptable pair of keys suitable for use by an asymmetric key algorithm. In this example the message is digitally signed with Alice's private key, but the message itself is not encrypted.
