I was learning about the classical ciphers and was looking up the methods to break them without the keywords and when I searched up "cryptanalysis of the trifid cipher" I couldn't find anything. I would be greatful for any help.(Find the outline of what the trifid cipher is here if you are unaware what it is)

    $\begingroup$ Welcome to crypto.stackexchange - I notice in the link you shared that there is a section labeled "cryptanalysis" that says "A good description of cracking the trifid cipher is provided in lecture 17 of the LANIKI Crypto Course Lessons". Did you notice/investigate this link? $\endgroup$ – Ella Rose Oct 25 '19 at 18:05

    $\begingroup$ Does that link help answer your question? If it does then you're welcome to post an answer to your own question. If not then you can edit your question to include any specific questions you might have about the analysis techniques presented there. $\endgroup$ – Ella Rose Oct 26 '19 at 15:27
  • $\begingroup$ I am unable to access the link as my devices return the message that they either couldn't find the page or that my search timed out. $\endgroup$ – Manav Oct 26 '19 at 15:37
