A disk cipher device of the Jefferson type from the 2nd quarter of the 19th century in the National Cryptologic Museum. The Jefferson disk, also called the Bazeries cylinder or wheel cypher, [1] was a cipher system commonly attributed to Thomas Jefferson that uses a set of wheels or disks, each with letters of the alphabet arranged around their edge in an order, which is different for each ...
Cipher disks had many small variations on the basic design. Instead of letters it would occasionally use combinations of numbers on the outer disk with each combination corresponding to a letter. To make the encryption especially hard to crack, the advanced cipher disk would only use combinations of two numbers.
In the history of cryptography, a grille cipher was a technique for encrypting a plaintext by writing it onto a sheet of paper through a pierced sheet (of paper or cardboard or similar). The earliest known description is due to Jacopo Silvestri in 1526. [ 1 ]
Owen's Cipher wheel. Owen's book Sir Francis Bacon's Cipher Story (1893-5) stated that Queen Elizabeth I was secretly married to Robert Dudley, Earl of Leicester, who fathered both Bacon and Robert Devereux, 2nd Earl of Essex, later ruthlessly executed by his own mother. [5] This was the basis for what became known as Prince Tudor theory. This ...
The recipient of the message must possess an identical grille. Copies of grilles are cut from an original template, but many different patterns could be made for one-to-one correspondence. The grille can be placed in four positions – face up and face down, upright and reversed – which increases the number of possible cell positions fourfold.

In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet .
