Well, as I stated in the description, the assembly code will function on Inte x64 with AES-NI support only, regardless the fact that the morpher itself is written in pyhton, since I use a custom AES implementation in x64 assembly. For more details you can see the issue number 1. So, unfortunately, you will not be able to use it on ARM... Such possibility will require recoding my implementation on ARM assembly and there are 2 possibilities:

1. Use AES-NI on ARM - some Allwinner and Broardcom processors suport that, but not only the support is limited and not officially claimed, it's poorly documented and not wide spread as well

2. Completely recode AES for ARM - a very time consuming task, especially considering that the shellcode target has to support AES-NI anyway

I will, nonetheless consider it as a future improvement, despite the fact that it can open the door for ARM shellcoding, it would be quit unrealistic, but perhaps someday I will do it, perhaps with a help of someone :)

I will update the README in any case

Thanks for your contribution :)
