.py file with license confusion, there was an issue with unpacking using method 3 #48

Closed OwnerCM closed 1 year ago

First of all, thank you for providing these solutions. . py file (Python version 3.10.12), using pyarmor and license to obfuscate, I used method 3 to unpack, and now prompt "Read file license. lic failed, No such file or directory". Do I need to obtain a license to execute? Also, could you please advise which method is better for confusing such files and whether all three methods require a license file? Looking forward to a reply. Thank you!

PyArmor has a built in license system. You will need a license to run it or you can manually patch the pytransform dll/so. The latter can be done through x64dbg.

@Svenskithesource Thank you for your reply! I have obtained the license file and unpacked the pyc file through method 3. The current issue is that Python version 3.10.12 cannot be decompiled using pycdc. I tried to restore the source code through bytecode, but the file is too large and has been abandoned.

This is a common issue and I can not help with that.

@Svenskithesource Thank you. I still want to ask about manually patching the pytransform DLL. I tried using x64dbg and found the keyword "Read file license. lic failed, No such file or directory", but as a beginner, I don't quite understand how to nop. If you happen to have a tutorial, could you please guide me? Thank you again! File attachment: _pytransform.zip

I am sorry but I will not give support about x64dbg, I recommend learning the basics of x64dbg and perhaps looking at my write-up for how I did it for the bootstrap restrict.
