is the answer the same legth as the plaintext

[Danika_Prasad]

do you mind sending it again. I can’t see or identify what the graph is showing

[try clicking on it again. Harry]

[ZB123]

Does analysing the bigrams mean that you should do it by blocks (e.g ABCDEFGH -> Ab-cd-ef-gh) or overlapping (ABCDEFGH -> AB-BC-CD e.c.t)?[both might be useful. Harry]

[Luna5379]

your first hint threw me in the complete other direction but this one brought be back on the right track! thanks!

[The_Code_Less_Traveled]

A note to madness: I sincerely thank you for your book on cryptography. It has truly been a great help this year and made me a 207% better cryptanalyst.

P.S. The critics were absolutely right!

A note to Harry: There is a bug with the pages on this particular thread. The main forum page shows it only has two, but clicking on it reveals that there are actually three pages.

P.S. Since when didn’t “English” stand for “American English” 😉

[hello123]

when will u be turning on feedback for answers?
[Probably at the weekend, we shall see! Have fun. Harry

[Astralica]

An excellent challenge; it was really rewarding to solve!

Hint: 2^2

Good Job Harry!

[madness]

I’m glad Harry took the advice I gave him a couple of years back: The B track (lately) focuses on a family of ciphers with shared characteristics.

I’ll be selling helpful hints later. The bidding will start at £100.

[Danika_Prasad]

can you please send a clearer picture. I can’t really see what is going on

[Try clicking on it! Harry]

[Cipher_PK]

Scary until it becomes squary (Harry feel free to black this out if it is too revealing at this stage – Merry Christmas)

[Yuuta]

Thanks Harry that helps a lot, though I do still have 2 questions left.

Now if the challenge ends on the 3rd of January, when roughly should we aim to have submitted a solid account of our 10b process by?

The Supercomputer told us we would be notified if our response was wanted, but where should we send this to?

As always, thanks for your help.

[You can contact us at [email protected]. Harry]

[ZB123]

Is this for A?? or B??

[Loa7er]

Harry, please delete the message #92873 above, the cryptic clue got cut off.

Two and two, as well as the square of the two, make four.
