Intel® - Digital Random Number Generator (DRNG) [Bull Mountain] interface for Python.

Intel® Digital Random Number Generator for Python

This module is an interface for Intel's RDRAND instruction.

RDRAND (for "read random"; known as Intel Secure Key Technology, previously known as Bull Mountain) is an instruction for returning random numbers from an Intel on-chip hardware random number generator which has been seeded by an on-chip entropy source.

RDRAND is available in Ivy Bridge processors and is part of the Intel 64 and IA-32 instruction set architectures. AMD added support for the instruction in June 2015.

Warning

Do not use rdrand/rdseed alone as a CSPRNG.

Installation

# Clone this repo.
git clone https://github.com/trusted-ws/python-rdrand

# Inside the directory.
cd python-rdrand

# Using sudo, compile and install the module:
sudo build.sh install

Testing

Open a Python 3x console and try to import:

import rdrand

An ImportError should be raised in case of your CPU doesn't support rdrand.
