openentropy
Measure and operationalize hardware entropy for research and security.
Collect entropy from on-device hardware sources, analyze source quality with statistical tests, and deliver raw or conditioned output through CLI, Rust, Python, and HTTP interfaces.
One workflow for entropy research, validation, and cryptographic deployment.
Components
Section titled “Components”Python SDK
Install via pip install openentropy. PyO3 bindings expose the full Rust API to Python with zero overhead.

CLI
cargo install openentropy-cli. Scan sources, stream bytes, run analysis, and monitor entropy in a live TUI dashboard.

Why Hardware Entropy?
Section titled “Why Hardware Entropy?”Most random number generators are pseudorandom — deterministic algorithms seeded once. openentropy continuously harvests real physical noise from your hardware:
- Thermal noise — three independent oscillator beats
- Timing and microarchitecture — clock phase noise, DRAM row buffer conflicts, speculative execution variance
- GPU and compute — GPU warp divergence, Neural Engine inference timing
- Network and sensors — DNS resolution timing, TCP handshake variance, WiFi RSSI, BLE ambient RF
The pool XOR-combines independent streams. No single source failure can compromise the pool.
