  May block up to 10 seconds or forever

メソッドの詳細

• shutdown

  public void shutdown​()

  Note - methods may hang or NPE or throw IllegalStateExceptions after this

  導入されたバージョン:

  0.8.8

• setSeed

  public void setSeed​(byte[] buf)

  オーバーライド:

  setSeed クラス内 java.security.SecureRandom

• nextInt

  public int nextInt​(int n)

  According to the java docs (http://java.sun.com/j2se/1.4.1/docs/api/java/util/Random.html#nextInt(int)) nextInt(n) should return a number between 0 and n (including 0 and excluding n). However, their pseudocode, as well as sun's, kaffe's, and classpath's implementation INCLUDES NEGATIVE VALUES. Ok, so we're going to have it return between 0 and n (including 0, excluding n), since thats what it has been used for.

  オーバーライド:

• nextInt

  public int nextInt​()

  オーバーライド:

  nextInt クラス内 java.util.Random

• nextLong

  public long nextLong​(long n)

  Like the modified nextInt, nextLong(n) returns a random number from 0 through n, including 0, excluding n.

• nextBoolean

  public boolean nextBoolean​()

  オーバーライド:

• nextBytes

  public void nextBytes​(byte[] buf,
                        int offset,
                        int length)

  Not part of java.util.SecureRandom, but added for efficiency, since Fortuna supports it.

• feedEntropy

  public void feedEntropy​(java.lang.String source,

  bitoffset - bit index into the data array to start (using java standard big-endian)

  bits - how many bits to use

• feedEntropy
