Class JWKMatcher

java.lang.Object

com.nimbusds.jose.jwk.JWKMatcher

@Immutable
public class JWKMatcher
extends Object

JSON Web Key (JWK) matcher. May be used to ensure a JWK matches a set of application-specific criteria.

Supported key matching criteria:

• Any, unspecified, one or more key types (typ).
• Any, unspecified, one or more key uses (use).
• Any, unspecified, one or more key operations (key_ops).
• Any, unspecified, one or more key algorithms (alg).
• Any, unspecified, one or more key identifiers (kid).
• Private only key.
• Public only key.
• Minimum, maximum or exact key sizes.
• Any, unspecified, one or more curves for EC and OKP keys (crv).
• X.509 certificate SHA-256 thumbprint.

Matching by JWK thumbprint (RFC 7638), X.509 certificate URL and X.509 certificate chain is not supported.
