Is the xenocryst just a mono-sub in a different language? No math or anything? Or am I missing something?
yep, its just monoalphabetic substitution in spanish.
Thank you!

Re: Protein Modeling C

Alright so, I have a little bit of a dilemma. I didn’t realized that 3D Molecular Designs sells different pre-build and regionals kits each year. Right now I have several 15 inch Mini Toobers and I don’t know whether I should put those together somehow, rush order the invitational kit, or use a diff...

whoever wrote it probably forgot to mention the key in the hint.
I was thinking that - but also Princeton.
We could reverse engineer the key and see if it's anything meaningful?
The key was "SCIENCES". I got that, but nothing was given other than ciphertext

Re: Codebusters C

Not with 8 letters of cyphertext, you can't. Sure, with a long cyphertext you can break Vigenere with frequency analysis techniques, but if all you have is an 8 letter cyphertext, your key could easily be 8 letters, and what you have is an encryption with an unknown one-time pad. By construction, t...

Re: Codebusters C

You actually can by figuring out what the key is by looking for coincidences between rows of shifts...et cetera. Theres a good video by Theoretically that explains it well. But yea. Just that ciphertext with nothing else. Not with 8 letters of cyphertext, you can't. Sure, with a long cyphertext you...

Re: Codebusters C

Nope. That's all they gave us. I have the answer key and everything i just dont know how they got that answer. You sure that was all they gave you? I don't think solving a Vigenère without any hints or a crib is even possible. The key could be literally anything... You actually can by figuring out ...
