.
Usage
public class Application {
public static void main (String [] args) {
try {
Map<String,Object> decodedPayload =
new JWTVerifier("secret", "audience").verify("my-token");
// Get custom fields from decoded Payload
System.out.println(decodedPayload.get("name"));
} catch (SignatureException signatureException) {
System.err.println("Invalid signature!");
} catch (IllegalStateException illegalStateException) {
System.err.println("Invalid Token! " + illegalStateException);
}
}
}

</dependency>
Credits
Most of the code have been written by Luis Faja https://bitbucket.org/lluisfaja/javajwt. We just wrapped it on a nicer interface and published it to maven. We'll be adding support for signing and other algorithms in the future.
FAQ
Why another JSON Web Token implementation for Java?
We think that current JWT implementations are either too complex or not enough tested. We want something simple with the right number of abstractions.
