Privacy-first, open-source, client-side tools and guides for cypherpunks. Everything runs in your browser, and nothing is sent to a server.
Live on the clearnet and Tor:
- How Monero Works: an interactive explainer with live cryptography
- Monero: address validator, integrated address generator, mnemonic tool, node config generator
- OpenAlias: checker, generator, pay
- Crypto: payment QR generator, payment URI decoder, unit converter
- Security and self-hosting: file checksum verifier, Diceware passphrase generator, Tor config generator, SSH hardening generator
The cryptographic code (Keccak-256, ed25519, and the Monero address, mnemonic, key image, subaddress, and Pedersen commitment routines) is checked against the Monero project's own test vectors. Open /tests/ in a browser to run the full suite and confirm every value matches.
