If that's the case, did anyone try disassemble the KG into readable code snip here?? or is it not possible?

One thing interesting is that the basic algorithm is the same for the 4 products and the programmer must have managed to find the private key that hash the required product id.. as explained by the text

Maybe just able to lcoate the 4 private key used and the basic algorithm in the code will assist in 'improvement' to the KG..
