Method Detail

secureRandom

public static SecureRandom secureRandom()

Returns JJWT's default SecureRandom number generator - a static singleton which may be cached if desired. The 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.

Returns:

JJWT's default SecureRandom number generator.
