Class AsyncFortunaStandalone

java.lang.Object
gnu.crypto.prng.BasePRNGStandalone
gnu.crypto.prng.FortunaStandalone
gnu.crypto.prng.AsyncFortunaStandalone
All Implemented Interfaces:
IRandomStandalone, Serializable, Cloneable, Runnable
public class AsyncFortunaStandalone extends FortunaStandalone implements Runnable
fortuna instance that tries to avoid blocking if at all possible by using separate filled buffer segments rather than one buffer (and blocking when that buffer's data has been eaten) Note that this class is not fully Thread safe! The following methods must be synchronized externally, they are not synced here or in super(): addRandomByte(), addRandomBytes(), nextByte(), nextBytes(), seed()
