Simple script testing JWT with groovy

jwt-test.groovy

@Grab("io.jsonwebtoken:jjwt:0.4")
import io.jsonwebtoken.Jwts
import static io.jsonwebtoken.SignatureAlgorithm.HS256


def key = "2193872103019283092174917"

def token = Jwts.builder()
                  .setSubject("Hello World")
                  .signWith(HS256, key)
                  .compact()

def name = Jwts.parser()
               .setSigningKey(key)
               .parseClaimsJws(token)
               .getBody()
               .getSubject()

println "/********** REPORT **********/"
println " => Key: $key"
println " => Token: $token"
println " => Name: $name"
println "/****************************/"
