Class DefaultJOSEObjectTypeVerifier<C extends SecurityContext>

java.lang.Object

com.nimbusds.jose.proc.DefaultJOSEObjectTypeVerifier<C>

All Implemented Interfaces:

JOSEObjectTypeVerifier<C>

@Immutable
public class DefaultJOSEObjectTypeVerifier<C extends SecurityContext>
extends Object
implements JOSEObjectTypeVerifier<C>

Default JOSE header "typ" (type) parameter verifier.

Example JWS header with a "typ" (type) parameter set to "at+jwt":

 {
   "alg" : "ES256",
   "typ" : "at+jwt",
   "kid" : "123"
 }
 

To create a verifier which allows the "typ" to be omitted or set to "JWT":

 JOSEObjectVerifier verifier = new DefaultJOSEObjectTypeVerifier(JOSEObjectType.JWT, null);
 

To create a verifier which allows a "typ" of "at+jwt":

 JOSEObjectVerifier verifier = new DefaultJOSEObjectTypeVerifier(new JOSEObjectType("at+jwt")));
