Usage

From source file:Main.java

public static void main(String[] args) throws NoSuchAlgorithmException {
    int numBytes = (new Integer("1111")).intValue();

    SecureRandom srand = SecureRandom.getInstance("SHA1PRNG");
    srand.setSeed(new byte[] { 1, 2, 3, 4 });
    byte[] bytes = new byte[numBytes];
    srand.nextBytes(bytes);/*from ww  w  .  j  a v  a 2s. c  o m*/
    System.out.println(new String(bytes));
}

From source file:MainClass.java
