Ok, I've been reading up on codes and ciphers, and figured it might be a fun exercise for us to have a Cipher Challenge.
Once a(n) (arbitrary length of time), I will post a new ciphertext for you all to decode. It will use a historic code or one I have made up, and will be entirely possible to solve. First person to completely decode it gets a point or something.
I strongly discourage 'cheating,' i.e. using a computer program to brute-force the ciphers. This is about testing your analytical and mathematical capabilities and stuff like that.
First ciphertext is the following:
I hope that's not an overwhelming amount. In fact, more characters would actually make the decryption [size=0](Read: Frequency Analysis) [/size]easier, but I don't want to scare the crap out of you guys before stuff actually gets challenging. If you don't like this ciphertext, then feel free to ask for a new one. If the common consensus is that we need a different encryption method, I'll get a new one. If there is not significant progress in (arbitrary amount of time), I will give hints.
First clue, just to get you guys rolling: It's a fairly famous speech.
Also, I recommend reading The Code Book,
by Simon Singh. This is by no means necessary, but it is a pretty cool exploration of historic codes, and how they were solved in the past.
