JWKSource
JWKSource is an API abstraction that supplies JSON Web Keys for cryptographic operations such as signing and verifying tokens.
Spring Security in Action, Second Edition
JWKSource is a component that supplies JSON Web Keys for cryptographic operations such as signing authorization-server tokens.
- How it is used
- Configures signing-key management for Spring Security authorization servers issuing non-opaque tokens.
- How deep it goes
- Builds a programmatic RSA example and explains persistent production storage, but defers detailed vault integration.
- Examples
- Uses a Java bean that generates a 2048-bit RSA pair, constructs an RSAKey, and assigns a UUID key ID.
- What you can do after
- Operate/configure Spring Security authorization servers with a signing-key source and recognize when durable key storage is required.

Spring in Action, Sixth Edition
JWKSource is an API abstraction that supplies JSON Web Keys for cryptographic operations.
- How it is used
- Supplies signing keys for JWTs issued by an authorization server.
- How deep it goes
- Shows a complete bean and RSA key-generation helpers, but defers resource-server verification details.
- Examples
- Shows an AuthorizationServerConfig bean that builds an RSAKey and returns keys selected from a JWKSet.
- What you can do after
- Build it from scratch as a Spring bean supplying an RSA JWKSet for JWT signing.
