Example 16 with AlgorithmParameterGenerator

use of java.security.AlgorithmParameterGenerator in project jdk8u_jdk by JetBrains.

the class TestDSAGenParameterSpec method testDSAGenParameterSpec.

private static void testDSAGenParameterSpec(DataTuple dataTuple) throws NoSuchAlgorithmException, NoSuchProviderException, InvalidParameterSpecException, InvalidAlgorithmParameterException {
    System.out.printf("Test case: primePLen=%d, " + "subprimeQLen=%d%n", dataTuple.primePLen, dataTuple.subprimeQLen);
    AlgorithmParameterGenerator apg = AlgorithmParameterGenerator.getInstance(ALGORITHM_NAME, PROVIDER_NAME);
    DSAGenParameterSpec genParamSpec = createGenParameterSpec(dataTuple);
    // genParamSpec will be null if IllegalAE is thrown when expected.
    if (genParamSpec == null) {
        return;
    }
    try {
        apg.init(genParamSpec, null);
        AlgorithmParameters param = apg.generateParameters();
        checkParam(param, genParamSpec);
        System.out.println("Test case passed");
    } catch (InvalidParameterException ipe) {
        // implementation in SUN doesn't
        if (!dataTuple.isSunProviderSupported) {
            System.out.println("Test case passed: expected " + "InvalidParameterException is caught");
        } else {
