LoopFortress Jingle (lib)

Jingle is a policy-driven JOSE Key Management Framework with declarative config, CLI, and runtime engine.

Features

General

• Uniform DX across symmetric + asymmetric + PBES2 + ECDH + AES-KW/GCMKW
• CLI for keygen, keystore and token operations

Keygen

• A declarative keygen architecture: spec → keystore → token factory (clean lifecycle flow)
• Purpose-based key groups (rotate under "access", "refresh", "userdata", etc.)
• Automatic kid assignment (user doesn’t have to care at all)
• Configurable key ID formatting (fun but harmless DX feature)

Keystore

• A type-safe JWK registry with strong typing for alg families & policies
• A clean keystore → runtime in-memory engine
• Optional external key import
• Optional strict/lenient policies and fallback logic for broken external integrations
• Automatic rotation with purpose groups

Token Factory

• Built-in JWT/JWS/JWE minting & verification
• A declarative token profile layer with mint & verify policies
• Mint & accept rules per token profile (structural authentication policy system)
