From "The Caching Place.com" website. Check out he website for future plans for   To avoid confusion, we have defined some terms that we use to refer to the different kinds of phrases used in the decoding process. Sometimes we use the terms decode and decipher interchangeably, but when you substitute each letter in a message for another letter it is actually called enciphering. A message that you can read that has not been enciphered is called "PLAIN TEXT"When it has been enciphered and is not readable then it is called "CIPHER TEXT"Sometimes a keyword is used to make a cipher more difficult to crack and is called "KEY TEXT" Definition of a "MYSTERY CACHE" from Groundspeak is the "catch-all" of cache types, this form of cache can involve complicated puzzles you will first need to solve to determine the coordinates. The only commonality of this cache type is that the coordinates listed are not of the actual cache location but a general reference point, such as a nearby parking location. Due to the increasing creativity of geocaching this becomes the staging ground for new and unique challenges. Easiest but least secure If you want to make a code that is easy for players to decipher then you can use this method where the decoder is set in a certain way and then left that way for the entire message. You could arrange to give the players a symbol by hiding it in a cache or some other way. Players would then find that symbol and then use it by aligning that symbol on the inner wheel of the decoder with the A and B on the outer wheel. For example, if you use the symbol as the key that is given to the players then they would align that symbol on the inner wheel with the AB on the outer wheel as shown. To create a coded message for the phrase "Avast Ye Mateys", you would first line up the symbol with the A and B on the outer wheel. Then find each letter of the message on the inner wheel and write down the corresponding letter on the outer wheel. Starting with the letter A from Avast, find it on the inner wheel and notice it lines up with the L on the outer wheel. The letter V on the inner wheel lines up with the J and so forth. When your players look at your encoded message hopefully they will have already found the symbol they need and they will line up the symbol on the inner wheel with the AB on the outer wheel. This step is identical to what you did to create the message. But now they need to do the opposite of what was done to create the message. They will need to find the letters on the outer wheel and write down the matching letter on the inner wheel. VIGENERE CIPHER with KEYWORD A much more secure method of sending a secret message is to use a Vigenere Cipher with a keyword. With this type of cipher you change the alignment of the code wheels after each letter in your message. For this example we will send the message "MEET AT THE LIBRARY AT SEVEN". We will use "SECRET" for the keyword. The first step is to write the keyword above the plain text lining up the letters one for one. Find the first letter of the key text (which is S) on the inner wheel and line it up with with the letter A on the outer wheel. Now find the first letter of the plaintext (M) on the inner wheel and take the matching letter (V) for the first letter of the cipher text. Align the next letter of the key text (E) on the inner wheel with the letter A on the outer wheel. Find the second letter of the plaintext (E) on the inner wheel and use the matching letter on the outer wheel (A) for the second letter in your cipher text. Follow this same procedure to finish enciphering your message. Place a Bid!
