Please unclobber this file. Look up the docs for git checkout and git show for some ways to get the old version back. There's also an entry on https://ohshitgit.com/ about this.

What is this file for? It probably shouldn't be added to git.

For now, the secret should be one line of text since we don't know that it's going to be hidden in a way be the previous step in the puzzle that will work with a multi-line hint.
I have plans for a v2 that's going to allow for much more free form secrets and clues but for now, make this one line.

Also, it occurs to me that this clue is probably not enough information for the player to write a solution: you need to give some information like "encrypted with AES-256 in chaining block mode with salt and the key you'll find in $PUZZLE/password, but reversed."

Be good to throw a -pbkdf2 in there so you don't get warnings about deprecated key derivations being used.

Your step script is actually logically flawed. And there are some issues with your solution script. You should try to get them working together.
