Weird how this video was located next to Lemmino's new video

[@marcandrewyss]

Thank you very much for the explanation. I finally managed to decrypt my cyphertext with your explanations. :-)

[@TriPabloski]

Thanks a lot! It helped me so much to understand it better :D

[@walidhouse]

the ciphertext in the last example is wrong ; you don't follow the order indicated by the columns

[@ProofofConceptMath]

Oh my gosh! You are right! I will figure out how to fix this (perhaps I'll need to replace the video). Thank you so much for pointing it out!

[@walidhouse]

@@ProofofConceptMath don't worry is our secret hhhhh..but you can do another short video on this and link it here in the end..

@@ProofofConceptMath can u explain it via text here clearly u haven't updated it, i badly need that last step.

Thank u💗

what do we do if we don't have the keys tho

[@MsANGLEPOISE]

thanks

[@Baph839]

Hi, thank you for the video. Is it possible do decrypt a message without knowing the key?

[@ProofofConceptMath]

Yes, but the methods are a bit complicated and it took a while for people to crack it. There's a book called "Secret History: The Story of Cryptology" by Craig Bauer that investigates the mathematics and history of this and other ciphers.

[@donpablo8762]

One question.. If I know the key and I have the square, how I can understand how long the second columns column if I want to decript message?

[@ProofofConceptMath]

Hi Don, good question. You'll want to count the letters in the ciphertext message and divide by the number of columns. This should tell you how many letters fit into each column. The only hitch is that you have to be a bit careful if the division has a remainder (in this example, it fit perfectly, no remainder). Keep in mind that in the encryption process, you fill out the chart on the right by rows, so the encrypter may end up with whitespace in part of the last row. That means some of the columns on the left are a bit longer than the ones on the right. The remainder of your division tells you how many columns are slightly longer, so you can mark these (draw yourself a box or line showing where the columns end). Then you'll know how to fill in the columns. I hope that helps!
