Returns the size in bits, l, of the random exponent (private value).

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    AlgorithmParameterGenerator paramGen = AlgorithmParameterGenerator.getInstance("DH");
    paramGen.init(1024);/*from   ww w . j  ava 2  s .c  o  m*/

    AlgorithmParameters params = paramGen.generateParameters();
    DHParameterSpec dhSpec = (DHParameterSpec) params.getParameterSpec(DHParameterSpec.class);

    System.out.println("" + dhSpec.getP() + "," + dhSpec.getG() + "," + dhSpec.getL());
}
