    Four practice Homophonic Substitution ciphers to cut your teeth on (from easy to more difficult). The word in the parentheses is a hint, and exists in the plaintext.

    You can't find quality content like this anywhere else on UA-cam. I've been searching a long time for a good tutorial on homophonic substitution ciphers. Thank you

    Hmm. I received a question about numbering, but for some reason, UA-cam isn't showing the question from that user when I look for it. Healy, if you're reading this, I apologize.
    Numbering starts at whatever key value you choose. If you want the key to be "code," then the first line will start numbering at 03 (A=01, C=03), then when it reaches 25 for the first line, it drops back to 01 and starts incrementing up again. Picking a different key letter (i.e. - "P") means that numbering for that line will start at a different value (16).

    where alphabet " J "...?

      Hi Robi, thank you for your question.
      For this cipher type, we can only have 25 letters for the alphabets. So J doubles up with I.
