Examples of javax.crypto.ExemptionMechanism

javax.crypto.ExemptionMechanism
This class implements the functionality of an exemption mechanism such as key recovery, key weakening, or key escrow.

        Provider mProv = (new SpiEngUtils()).new MyProvider("MyExMechProvider",
                "Provider for ExemptionMechanism testing",
                srvExemptionMechanism.concat(".").concat(defaultAlg),
                ExemptionMechanismProviderClass);


        ExemptionMechanism em = new ExemptionMechanism(
                new MyExemptionMechanismSpi(), mProv, defaultAlg) {
        };


        Key key = new MyExemptionMechanismSpi().new tmpKey("Proba", new byte[0]);


        assertFalse(em.isCryptoAllowed(key));


        em.init(key);
        assertFalse(em.isCryptoAllowed(key));


        em.genExemptionBlob();
        assertTrue(em.isCryptoAllowed(key));


        Key key1 = new MyExemptionMechanismSpi().new tmpKey("Proba",
                new byte[] { 1 });
        assertFalse(em.isCryptoAllowed(key1));


        em.init(key1);
        assertFalse(em.isCryptoAllowed(key));
