We have a winner in the second F211 Crypto competition. I made this one a lot easier than the first one (although some have said too easy) by using a Ceasar-Shift cypher instead of the modified dual source book code one that I used before (and which was far too difficult for people).
As promised, here is both the Ciphertext and the plain text.
The cyphertext is
Sa odwhh zabajz kqn enhwjz, slwpzrzo pda ykop izu xz, sa odwhh becdp kj pda xawydao, sa odwhh becdp kj pda hwjzejc cnkqjzo, odwhh becdp ej pda beahzo wjz ej pda opnaapo, sa odwhh becdp ej pda dehho; sa odwhh jaran oqnnajzan.
The original plain text is as follows:
“We shall go on to the end. We shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our island, whatever the cost may be. We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender” Winston Churchill May 1940.
Congratulations to ‘BM’ who is the winner of this month’s competition and they have been notified that they have won.
nice job 😀
Thanks. It bothers me that people rely so much on computer encryption and never play around with manual encryption. Manual encryption is a fun thing to play around with. The first one I did was scarily difficult and used a modified dual source book code with extra characters to designate the letters of words that were not in the code books.
My next crypto competition will be pitched some way between the really easy second comp and the brain-aching first one.
