I had used this tool, but recently, I stumbled upon on a blog post and this is what the author of the tool said:
"I am the author of WinMessage. The encrypted installer was created by a random chinese tool I found on the internet. I myself was not aware of its internals. I used it because it offered to compress multiple setup files into one. After reading about the risks on Reddit, I removed the installer. You will still be able to use the project, but must now build it from source. I hope this will help people trust the software, and I apologize for my not taking a closer look into the installer."
If your device can be jailbroken. then all you have to do is install
this tweak.
