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.
