Fifth Clue

This is a clue for beginners.

The home page now shows two of the Ciphers used in Competition #1. The Vigenere Cipher is an example of a polyaphabetic cipher, hence the same letter can be substituted by different encyption symbols.

However, the tutorials under some of the code cracking links show you ways of defeating the Vigenere Cipher without knowing the key. Good luck!


Fourth Clue

It has been sometime, but at last here is the fourth clue

There are lots of permutations
Before congratulations

So just before you start to whine!
The rotor start is twelve four nine


 

Third Clue

Some of you are getting quite close now! The next clue for the prize code breaker competition #1 is in the form of a riddle.

The last part's hard work, so remember to eat
The use of this applet will help take the heat

There's lots of combinations before the story can be told
A specific picture of the rotors is yet to unfold ...



Second Clue

I have started receiving prize entries which are incomplete where the code cracker has assumed that the cipher contains some random filler as well as the message.

For all code crackers out there, there is no filler in the cipher, it is all message.

Good luck with the decryption.


 

First clue

The first clue for prize codebreaker competition #1 is out now. Click on the heading to find out more and remember there is £100 riding on this competition

This cipher uses only known encryption techniques that are all described in Simon Singh's "The Code Book", see the code cracking section for the Amazon link.

However, to make it a bit harder there are multiple layers of cipher. In other words, a cipher within a cipher etc... Each cipher layer should have enough header to provide the clues for cracking.

If not, then watch this site for the next clue!
