Generate cryptographic secrets with CSPRNG randomness and honest entropy accounting: random bytes (hex/base64/base64url), passwords with character-class guarantees, pronounceable strings, UUIDs, prefixed API keys, TOTP seeds (base32), and asymmetric keypairs (Ed25519, ECDSA P-256, RSA-2048) as PEM + JWK. Unbiased rejection sampling. Secrets are never stored or logged. POST a JSON body like: {"type":"password","length":24,"symbols":true,"count":2}
