Understanding JSON Web Keys (JWK)

A JSON Web Key (JWK) is a JSON data structure that represents a cryptographic key, as defined in RFC 7517. JWK format provides a standardized way to represent cryptographic keys in JSON, making them easy to exchange between systems, particularly in modern web applications, APIs, and security protocols like JWT, OAuth 2.0, and OpenID Connect.

Key Benefits:
  • Standardized Format: Industry-standard JSON structure for key representation
  • Easy Integration: Native JSON format works seamlessly with web APIs and JavaScript
  • Self-Describing: Key metadata (algorithm, usage, etc.) is embedded in the key itself
  • Flexible: Supports multiple key types: RSA, Elliptic Curve (EC), Octet Key Pair (OKP), and Octet Sequence
