The Galactic Republic is in crisis, the Droid Army has intercepted some messages between the republic forces. Help them to decrypt these !

Only basic cipher / encoding method are using here.

  1. General Grievous ! I think a Jedi is approaching...

Just a basic translation.

  1. The key can keep you away from death.

Hint 2

Alphabetical substitution, you just need to find the right key

  1. Just chronological

    TFJBYDU

Hint 3

7 letters, for 7 films

    $\begingroup$ I did not downvote this puzzle, but many PSE people are not fond of puzzles like this where basically the question is "can you guess the cipher I used?". See puzzling.meta.stackexchange.com/questions/1717/… for advice on how to make cipher questions that might be better received. $\endgroup$

  • $\begingroup$ Already read that post, but as i say in my post, maybe i was not clear, but the goal is to find the key not the cipher, i don't ask to try all the cipher but if people are too busy to try at least the most common, they can downvote me, no probleme with that $\endgroup$

$\begingroup$

The first cipher

is simply ASCII represented in hex. "HELLO THERE".

The second cipher

says "THE CHANCELLOR IS A TRAITOR". It looks to me like a standard keyword + rest-of-alphabet substitution cipher, with key PLAGUEIS.

The third cipher

seems like it plainly has too little information, but pondering the hint leads to the following thought: the relationship between in-universe and out-of-universe chronology for the Star Wars films is given by the numbers 4,5,6,1,2,3,7, and if we move backwards by those numbers of letters in the alphabet from TFJBYDU we get PADAWAN which I take it is the intended answer.

  • $\begingroup$ First and second are good. You're on the way for the third,but it's not a vigenere. Think about chronological. $\endgroup$

  • $\begingroup$ Darn, I guess I should've just posted my answers instead of trying to find the 3rd one first... Note that the OP actually says "Just chronological", so I figure it makes sense to take the movies on chronological order, but even then I couldn't make sense of it. I've also tried using the year of release and even length of the titles, but it didn't seem to give anything useful either. $\endgroup$

  • $\begingroup$ Yeah, the third seems like a pure "guess what I'm thinking" puzzle. If anyone else wants to put more thought into solving it then I'll happily urge Skyvask to accept their answer in preference to mine; for my part, trying to enumerate the dozens of things ... oh, wait, I've got it. About to update my answer. [EDITED to add:] Now done. $\endgroup$

  • $\begingroup$ yeah, thanks to try at least, i will avoid this type of puzlle next time $\endgroup$

  • $\begingroup$ Ah obviously... that makes sense. I had the solution of the 3rd one right in front of me while trying to solve it, but I didn't see it :P $\endgroup$
