NodeCrypto — Visual Cryptography Engineering Platform
NodeCrypto is a free, node-based workbench for designing, inspecting, and verifying cryptographic workflows. Connect nodes on a canvas to build byte pipelines, run them against NIST and RFC test vectors, and see every intermediate value.
What you can do
- Build workflows from 83 cryptographic and byte-processing nodes: AES, ARIA, SEED, ChaCha20, RSA, ECDSA, Ed25519, X25519, ML-KEM, ML-DSA, SHA-2/3, BLAKE2/3, HKDF, PBKDF2, Argon2, scrypt and more.
- Verify implementations against published known-answer test vectors.
- Write custom logic with the built-in scripting language.
- Run everything locally in your browser: keys, plaintexts and workflows are never sent to a server.
- Drive workflows from AI agents through the NodeCrypto MCP server.
