Hi Mario,
Before we do anything else please try the following:
* Create a new virtualenv
* Install the latest paramiko and cryptography into the virtualenv
* Run your code in that virtualenv and see if you get the error
If you do, please try to reduce the code until you have the minimum number
of lines that can reproduce the problem and then provide that code to us.
We can then replicate your issue and try to help you fix it.

Good morning,
Sorry the inconveniences.
I write because obtained the next exception and I don´t know found solution.
The same code works perfectly with python 3.7 and cryptography 2.4.4 but I
don´t use python > 3.5 because I need execute my code in a Windows XP.
I make different test:
1. python 3.4.4 + crytpgraphy=2.4.2
2. python 3.4.4 + crytpgraphy=2.5
3. python 2.7.9, but I tried install cryptography==2.9 obtained more
errors.
Please can you help me?
Regards,
