JWK (JSON Web Key)

A JWK (JSON Web Key) is a standardized format for representing cryptographic keys (used for encrypting data or verifying digital signatures) in a structured way using JSON (JavaScript Object Notation). It makes it easy to share and manage keys across different applications and services securely. Essentially, a JWK contains the necessary details about a key—like type, usage, and value—so that systems can reliably use it to validate identities or protect information without exposing sensitive details. It's a key component in secure digital communication, especially in web-based authentication and data exchange.
