Default retrieve xceed zip decryptor password from a program

I have app which is packed using boxed app
I have it unpacked and extracted dependencies.
The program is written in .net and obfuscated using crypto obfuscator so I cleaned the code and here it is

The program has folder called db which has many .dat files.
These dat files are zip files but we need to change "mc" to "PK" using hex editor and rename file as *.zip. The zip files contain xml files which i want to extracted however they are encrypted.

I launched the app using .net tracer and set BP on reading dat file by changing one of the dat files in the db folder. It seems that it checks for some password to decrypt the zip files
Here is the reflector image

I hope some one help me finding the pass to dat files
