Having some trouble cracking this cipher (this is part of a homework assignment for a cryptology class) I've looked at letter frequencies but I'm not sure what else there is to help me.
Given the encrypted string, TNFOS FOZSW PZLOC GQAOZ WAGQR PJZPN ABCZP QDOGR AMTHA RAXTB AGZJO GMTHA RAVAP ZW
, the word LIBERTY
is encrypted somewhere in the ciphertext.
From that, I find A and Z line up almost perfectly to E and T given a frequency chart and based off of that, I can pinpoint possible locations of the word LIBERTY (blue text). But after that, I don't really see anything to do to further decrypt it. With no spacing I cant really make out any words
LIBERTY
relative to the start of the plaintext are possible for a 67-character plaintext? Can you exclude some of these given the particular ciphertext and knowing it's monoalphabetic substitution)? Would your eye+brain be enough to find the plaintext among what remains, if you wrote a program that displays the candidate plaintexts with.
for characters where there's a remaining ambiguity? For short plaintext that approach has lower probability to miis than pure frequency distribution. $\endgroup$
