gcprand is a Python library for gathering Global Consciousness Project Dot data and generating psychorandom numbers seeded by nooetic activity. It is a thoroughly unconventional entropy generator in the tradition of Cloudflare's LavaRand.
Reading through the code could provide insights into how to pull and analyze the data myself.
Python implementation of Dropbox's realistic password strength estimator.
EntroPy is a Python 3 package providing several time-efficient algorithms for computing the complexity of one-dimensional time-series. It can be used for example to extract features from EEG signals.
EntroPy cannot be installed using pip or conda. There is already a package called entropy on the pip repository, which should not be mistaken with the current package.
Uses the mathematical analysis modules that you'd expect.
Can calculate permutation, spectral, singular value decomposition, appromate, sample, and Lempel-Ziv entropy. Can calculate Petrosian, Katz, Higuchi, and detrended fluctuation fractal dimensionality.
An open-source utility for Linux that uses an attached webcam to seed the kernel's random number generator for cryptographic purposes.
An open source utility for Linux that seeds the kernel's random number generator with data pulled from an attached microphone.
A command line utility that calculates the amount of informational entropy in arbitrary fields of data. Useful for cryptanalysis and data compression research
A method for distributing cryptographic entropy in the form of numerical values to systems that need it. Collects entropy from other systems and hashes it into the pool. While I can't vouch for how much entropy is in those values it seems interesting to experiment with.
Not true but hilarious facts about security and cryptography guru Bruce Schneier.
An in-depth description of how pseudorandom number generators work (specifically, in Linux and OpenBSD) and how to improve the entropy pools of systems. Includes instructions on testing the entropy available, running an entropy gathering daemon to keep the entropy pool full, and how to rig up a wireless network interface to seed the kernel entropy pool.
A daemon that adds noise to the Linux kernel's entropy pool to maintain a certain amount of randomness. Every little bit helps.
An excellent lesson on entropy (in the mathematical sense) using interactive sheep and grade school physics as illustrations.
The primary instance of the NIST Randomness Beacon. Has a REST API for access (which is going to change). Pull random numbers out of it but don't trust them because you didn't generate them yourself.
FOSS software that uses an RTL-SDR radio receiver as a cryptographic entropy generator. Pulls samples of RF noise, processes them, and seeds an RNG with it. Written in C.
