Decoding the Message
You might be thinking that this may be a little too advanced for you. This is an abnormal code breaking geocache. Most caches only use one cipher, making it pretty easy to get the hint. Codes such as the one mentioned above are rare, and they are only for advanced code breakers.
Some codes require that you have a key to break them. Many do not, but you should closely read the description to make sure.
If you want to go after a cache that requires a bit of code breaking, you do not have to be a wizard at the task. There are many free online code breakers especially for geocachers. My Geocaching Profile has a code breaker for the Vigenere Cipher. This code breaker works by searching through the code and trying to determine the length of the key.
It then looks for repetition of common words such as “the." Based on the estimated length of the message and the spaces between words, the code breaker then tries to determine the text. It does this based on multiple guesses.
Another free code breaker is the Secret Code Breaker, which breaks the Caesar Cipher. You have to download the zip file to use this program.
Both of these programs work in much the same way. You copy and paste the encoded message into the Key sections and press the Code Break or Key button. The program usually takes about one minute to decode the message.
Once done, you will see the decoded message in the Message box.
