Congratulations to QuadWrays and unclebruce for being FTF!
Code are wonderful things. What we all now know as the concept of privacy, was something that has always required secret codes to maintain. While today we have codes that are practically impossible to crack, the historical ones are much weaker with the knowledge and computer power we have today. One of the earliest of the modern cryptographers that apply math to the problem of cracking codes was Charles Babbage

Unfortunately Chuck suffered from much of the same problem we find with some cryptoanalysts in more recent times. An unwillingness to publish their findings to advance the general knowledge of the subject. This is because we can not create secure codes without a thorough understanding of all the ways that codes can be broken! So here is the code you must solve to find this cache.

The cache contains some SWAG as well as a small plastic bag with two unactivated trackables for the first to find this one. The trackables are a FTF geocoin and a travel bug. Best wishes in your search!
