You will need:
1- Extract the contents of the trophy keys zipfile into your %USERPROFILE% folder (in my case it's C:\Users\zecoxao). You will have it as C:\Users\zecoxao\ps4keys\<keys_here>
2- Navigate to:
And find the TITLE ID of the game which you want to resign the trophy file
3- Copy the CUSA title id folder to a safe place.
4- Open npbind.dat inside with Hexeditor:
Here we can see that game CUSA00434 has correspondant trophy file NPWR05974
5- Now that you know correspondant id, navigate to:
and find folder with that id and place it somewhere safe on your pc. you know have two things: your np communications id and your trophy file
6. Open a command line and type the appropriate command with trp_resigner.exe:
Following the example above.
7. Congratulations! You now have a resigned debug trophy
