then otherss, give a clue me pleaaae

Hello, keep going with your method, you are one the right track. By the way, the plain-text is in french

Hey
I get some words french like [Ech0 : spoil]
I am in the right way ?

what is the hint for the key?

Did you figure out that????? :’-(

If you dont speak french, it’s more difficult. By the way one of these words = [Ech0 : spoil]. that show me that we are playing a french game. In my opinion it’s not a difficult crypto, but as my teacher said....think out of the box.

Thanks @Mathman, but having a single known word makes this too simple - perhaps only necessary to have 2 or 3 characters sequence of the decoded message in order to complete by any non-french language.

I have solved the cipher and got the clear text.
And followed the instructions in the "hint".
But it gives me that it is wrong, am I missing something?
