A Crib is a branch of cryptography related to decrypt coded messages when one is not thought to be capable to. Crib bedding is actually concerned about the plan or the scheme that is used to design the code of the crib. It makes use of the science of writing messages secretly. There are countless ways and devices which may be brought in use so that a message can be hidden from the unwanted reader, for instance, invisible ink, but the crib bedding is only applied to converting or rather translating content into code. The technique of decrypting codes as well as ciphers without any proper key is called crib or technically as cryptanalysis.

Cryptology(Six Celebrity Geeks Uncovered) is a branch of technology that encompasses cryptography & crib. In enciphering, every alphabet of the content is substituted by some other letter, digit or figure; in encrypting, whole sentences, words or syllables are treated. The coding scheme is an agreed upon and accepted collection of rules through which text or content is transformed from one particular form to some another one.

The starting of cryptography and crib bedding can be recalled to the hieroglyphs, from early civilization of Egypt (somewhat around 1900 B.C.).

A few examples for Cribs and ciphering are as follows:

It has been a very vital technique for diplomatic and military secrecy. The holy book, Bible is stuffed with instances of crib bedding; furthermore legendry people throughout our history have used cribs. This list includes Julius Caesar, Louis XIV, Charlemagne, Mary Queen of Scots, and Alfred the Great.
