Tool for encrypting a UE4 .pak file?

[Cboss1122]

Hi, so I've recently been trying to develop a cheat for a game called "3on3 Freestyle Rebound" on steam. I was able to unpack the games main .pak file using quickbms and a public AES key that i found online. After changing what i wanted to change, i packed the files into a new .pak file using a tool called u4pak but I believe that the game will be unable to read it unless I encrypt the contents of the .pak file with the AES key i used earlier. Does anybody know of a tool or a method that would allow me to encrypt this .pak file with my AES Key?

You don't need to reencrypt it again. It will read unencrypted for 99%.
