decompiling official single missions

[gadolinite]

The single missions are in PBo files.  I de-pboed them and the mission.sqm, and the other main files are bianiarized or somehow encrypted.  How to you decrypt them?  If there is a way to get these official missions into the mission editor, I could learn a lot.

I use PBO decryptor v1.5 and it works just fine.
