Constructor Detail

SecureRandom

public SecureRandom()

Constructs a secure random number generator (RNG) implementing the default random number algorithm.

The returned SecureRandom object has not been seeded. To seed the returned object, call the setSeed method. If setSeed is not called, the first call to nextBytes will force the SecureRandom object to seed itself. This self-seeding will not occur if setSeed was previously called.
