I desperately sought the decoding. I think the old key still works, but the script structure in bms doesn't match the new structure. Hope someone can help write a code that is suitable for the new structure.

I have several ktx files encoded from png files (the current png file is also an encrypted file but I can decrypt them). I used some softwares like Mali or PVRTexTool but can't open ktx file. I hope someone can help me method to decode this ktx file. Attachments include the ktx file and the original...

hope someone can decrypt the ktx file
