DEFAULT_SECURE_RANDOM

public static final java.security.SecureRandom DEFAULT_SECURE_RANDOM

JJWT's default SecureRandom number generator. This RNG is initialized using the JVM default as follows:

 static {
     DEFAULT_SECURE_RANDOM = new SecureRandom();
     DEFAULT_SECURE_RANDOM.nextBytes(new byte[64]);
 }
 

nextBytes is called to force the RNG to initialize itself if not already initialized. The byte array is not used and discarded immediately for garbage collection.

alg

protected final SignatureAlgorithm alg

key

protected final java.security.Key key
