Hi Senocular, e_v,
Thanks for the reply Senocular and for e_v thanks for the original question.
The thing is that I am going to try and implement that tutorial in actual code and I will post my progress here.
With your support ( especially Senocular’s support as he is the true expert ) and guidance we can try and approach a system as secure as is possible, maybe.
Any ideas are welcome from one and all !
Thanks !
