Python NIST Randomness Beacon

WARNING: DO NOT USE BEACON GENERATED VALUES AS SECRET CRYPTOGRAPHIC KEYS.

Installation

Prerequisites

A required library pycryptodome is used with nistbeacon.

Ubuntu, and other Linux-based users should have python3-dev installed.

apt-get install python3-dev

Installing nistbeacon

To install the beacon library, simply use pip:

pip install nistbeacon

Beacon Usage

It is easy to use the beacon. Most queries are performed through NistBeacon which produces NistBeaconValue objects.

Beacon Sample Code

from nistbeacon import NistBeacon

# In the examples below I will be using 1447873020
# as my <timestamp> when required

# Current Record (or next closest)
# https://beacon.nist.gov/rest/record/<timestamp>
record = NistBeacon.get_record(1447873020)

# Previous Record
# https://beacon.nist.gov/rest/record/previous/<timestamp>
prev_record = NistBeacon.get_previous(1447873020)

# Next Record
# https://beacon.nist.gov/rest/record/next/<timestamp>
next_record = NistBeacon.get_next(1447873020)

# First Record
# https://beacon.nist.gov/rest/record/1378395540
first_record = NistBeacon.get_first_record(download=True)

# Last Record
# https://beacon.nist.gov/rest/record/last
last_record = NistBeacon.get_last_record()

# Verify the record and the record chain
record_chain_result = NistBeacon.chain_check(1447873020)
