Re: Challenge "Alberti Challenge - Part 2"

Thanks for the nice comment, I appreciate it!

Yes, I know. But a specific one of the two plaintexts was asked for as the solution and at first I had the wrong one. Thanks for the comment anyway.

German version now has the ciphertext, too, thanks! Downloaded it from the English version anyway ;-)

The fix is in only for the English version, not the German one.

Congrats on solving the challenge, madness! And you are right, you can't assume that the plaintext starts on a word boundary.

I get that. But I don't think it's relevant, the unicity distance is a function of the cipher system/cipher algorithm, not of the specific message. As I said i…

Not sure I can follow that logic. If, for example, you have a simple monoalphabetic substitution but the message does not contain alle available letters from t…

Dear George,

thanks for the nice comment and congratulations to being the first to solve the challenge!

Seems I messed up the unicity distance calculation, s…

The link in the challenge description is broken. This seems to be the correct link: https://github.com/Networc/networc.github.com/blob/master/_posts/2012-04-25…

Hi tryone144, thanks for fixing the verification process! I noticed that the challenge is now displayed as solved in my account. Happy Easter days to everybody!

Re: Challenge "ECDH-Key Exchange for Beginners"

I think I solved the affine cipher and got a solution which "looks right". It is rejected, however. Could anyone who already solved this check my solution? Th…

Re: Challenge "Kaskade-S/T — Part 1"

I easily found the key and have a 26key file which reproduces the plaintext when used with the provided Python code. However, like many others, I have trouble …

To answer my own question: I accidentally swapped the two ciphers in my spreadsheet, so I submitted the wrong one's final 10 chars.

All good now ;-)

Re: Challenge "The SZ42 Challenge — Part 3"

My solution is rejected even though I'm pretty confident it is correct. I deciphered both cipher texts (including identifying the original sources of the plain…

Re: Challenge "The T52 Sturgeon Challenge — Part 1"

 On March 11, 2022, 7:54 a.m.

In the provided file 'T52 Functional Description', section 'Code Wheels', is an obvious error: it's stated 'those wheels have 47, 53, 59, 61, 64, 64, 67, 69, 7…
