Bazeries Cipher

• Cylinders such as the Wheel cipher use a set of
  wheels with the alphabet in different, random
  orders around each wheel
• Bazeries developed one in 1891 with 20 cylinders

• The key is the order of the cylinders
• For example using the order 1, 5, 3 and the word
  hat

Using CAP

• Select Bazeries under the cipher menu

The first cycle it will take the line below the
plaintext,the second cycle it will take the 2nd
line below the plaintext, . . .
