National Cipher Challenge

For anyone interested in learning about writing or decoding secret messages this is quite interesting:

www.cipherchallenge.org/

The ciphers used are mostly those in use prior to the Second World War.

There are tutorials on the website.

The target audience is A Level students and the prizes are for those registered through their school, however anyone can register and have a go at the ciphers (but you won't be eligible for the prizes).

It starts on Oct 9th, as I've had a go at it before I haven't decided yet if I'll do it again this year.

Edit: I just thought I'd add that you should be able to complete quite a few of the challenges by just using pen, paper and some online tools (the later challenges will need some simple computer programming)

  • I took a quick look at this. I can imagine it could be fun, but also very frustrating.

    I was wondering whether you could have a way to index into Pi, say by using the length of the first sentence, then using that as a random number to give variable offsets for letter of the cipher.
