I feel your pain and think it's time that a way to crack passworded mission files is finally found after, what, 18 years?

Surely technology has come far enough that the average "gamer" PC could brute force whatever encryption is being used... in fact I have a theory that the password protected mission file output is not actually encrypted at all but simply compressed.

Here is my idea for finding a way to unlock missions:

Using a simple test mission file that has been saved twice. CopyA and CopyB. The actual contents of the mission is not important so long as they are exact copies of the same mission. CopyB has been saved with the password 123456.

CopyA using no password: https://pastebin.com/L6hnTiQV

CopyB using the password 123456: https://pastebin.com/FXpdbnQe

Now it may be possible to work backwards... which method can produce an output of copy A, given the input of copy B. Or a method which can output the password "123456" using copy B and, say, the mission briefing text. Maybe someone here is a mini-expert on compression algorithms can at least point us in the right direction.
