I just encript several exe with this tool and nither Refox 9 nor UnfoxAll 3.0 could decompiled them.

I also encripted other exe with a software named sollok that Pilino shared here and the decompilers couldn't make it either.

another info, UnfoxAll 3.0 can decompile an exe branded by refox 8.25 Level I+, but couldn't decompile a Refox MMII level I+ branded exe.
