Usage

From source file:org.casbah.provider.PKCS1EncodedKeySpecTest.java

@Test
public void testToRsaKeySpec() throws IOException, CAProviderException {

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    IOUtils.copy(this.getClass().getResourceAsStream("/caplaintext.key"), baos);
    byte[] encodedKey = baos.toByteArray();
    PKCS1EncodedKeySpec encodedKeySpec = new PKCS1EncodedKeySpec(encodedKey);
    RSAPrivateCrtKeySpec privateKeySpec = encodedKeySpec.toRsaKeySpec();
    assertNotNull(privateKeySpec);/*from  www . ja va 2 s  .  c o m*/

    assertEquals(TestKeyValues.MODULUS, privateKeySpec.getModulus());
    assertEquals(TestKeyValues.PUBLIC_EXPONENT, privateKeySpec.getPublicExponent());
    assertEquals(TestKeyValues.PRIVATE_EXPONENT, privateKeySpec.getPrivateExponent());
    assertEquals(TestKeyValues.PRIME1, privateKeySpec.getPrimeP());
    assertEquals(TestKeyValues.PRIME2, privateKeySpec.getPrimeQ());
