An upgrade was pushed to Rmutate that will obfuscate your python variables with the -o hex_mod when using the -f6 action.

example

var1='hello world'

var1 would get a random variable and the change may look something like

z6='hello world'

Note: The process can take quite a long time, maybe several minutes if your code is long enough.
I added a counter that updates every time it mods 100 variables; that way you know your computer didn’t freeze.
