Key Pair API
Generate cryptographic key pairs on demand — RSA (2048/3072/4096), elliptic-curve (P-256, P-384, P-521, secp256k1), Ed25519 and Ed448 — returned as PEM (SPKI public key, PKCS#8 private key) and, optionally, as JWK. Perfect for spinning up JWT/JWS signing keys, TLS and SSH experiments, test fixtures and demos. Pure local generation with Node's crypto (no third-party service). Note: for development, testing and education — generate keys for production systems offline or in an HSM, never trust a remote API with real private keys. Live, nothing stored. 3 endpoints. Distinct from JWT signing, password generation and hashing.
