How to Create Secret Codes and Ciphers. Codes are a way of altering a message so the original meaning is hidden. Codes and ciphers book pdf, this requires a code book or word. Ciphers are processes that are applied to a message to hide or encipher information.
These process are reversed to translate or decipher the message. Write out words in reverse. This is a simple way of encoding messages so they can’t be understood at a glance. A message like “Meet me outside” written in reverse would instead be “Teem em edistuo. This code can be easily solved, but it can be useful if you think someone is trying to peek at your message. Reflect the alphabet in half to encipher messages. Write out the letters A through M in a single line on a piece of paper.
Directly beneath this line, write out the letters N through Z also in a single line. Change each letter of messages to the opposite letter of the two lines of letters you have written out. By using a reflected alphabet, the message “Hello” would instead become “Uryyb. Write out the letters A through I in the grid going from the left to right, top to bottom. The first row is made up of the letters A, B, C.
The second is made up of D, E, F. The last row is made up of G, H, I. Create a second tic tac toe grid with dots. Draw another tic tac toe grid beside the first one. Fill the grid in with the letters J through R, similarly to the first grid. Write out two X shapes beneath each grid. These two X shapes will also be filled with letters to complete your pigpen cipher key.
In the second X, place dots in the open spaces surrounding where the X crosses so there is a dot on each side of the center of the X. X shape, write S in the top of the X, T on the left side, U on the right, and V on the bottom. In the second X shape, write W in the top of the X, X on the left side, Y on the right, and Z on the bottom. Use the grid surrounding the letters to write in pigpen cipher.
Use your pigpen cipher key to translate messages into and out of pigpen. Use a date shift cipher. This might be something with personal significance, like a birthday or the day you graduated college, but it could be something impersonal, like the birthday of George Washington. Write out the date as an unbroken string of numbers. This is the number key. Encipher your message with the date shift number key. Write out your message on a piece of paper.
Underneath the message, write out a single digit of the number key for each letter of your message. When you reach the last digit of the number key, repeat the key from the beginning. This holds true for words start with a cluster of consonants. Recognize the limitations of codes. Code books can be stolen, lost, or destroyed. Even so, codes can condense long messages into a single signal word, making them great time savers.
