Method Detail

testRSAKeyPairGeneration

public void testRSAKeyPairGeneration()
                              throws java.lang.Exception

Throws:

java.lang.Exception

testRSAGeneratedKeyPairSigningCapabilities

public void testRSAGeneratedKeyPairSigningCapabilities()
                                                throws java.security.GeneralSecurityException

Throws:

java.security.GeneralSecurityException

testRSAGeneratedKeyPairEncryptionCapabilities

public void testRSAGeneratedKeyPairEncryptionCapabilities()
                                                   throws java.security.GeneralSecurityException

Checks that a generated RSA key pair encrypts and decrypts with every RSA padding scheme.

A generated key may be held by the implementation in a form that differs from a key loaded through a KeyFactory, so the cipher path of RSACipherTest, which loads its keys, does not cover it.

Throws:

java.security.GeneralSecurityException - if the key generation, the encryption or the decryption fails

testRSAValidateGeneratedKeyPairEncoding

public void testRSAValidateGeneratedKeyPairEncoding()
                                             throws java.security.GeneralSecurityException

Throws:

java.security.GeneralSecurityException

testECKeyPairGeneration

public void testECKeyPairGeneration()
                             throws java.lang.Exception

Throws:

java.lang.Exception

testECGeneratedKeyPairSigningCapabilities

public void testECGeneratedKeyPairSigningCapabilities()
                                               throws java.security.GeneralSecurityException

Throws:

java.security.GeneralSecurityException

testECGeneratedKeyPairKeyAgreementCapabilities

public void testECGeneratedKeyPairKeyAgreementCapabilities()
                                                    throws java.security.GeneralSecurityException

Checks that two generated EC key pairs of the same curve agree on an ECDH shared secret.

A generated key may be held by the implementation in a form that differs from a key loaded through a KeyFactory, so KeyAgreementTest, which loads its keys, does not cover it.

Throws:

java.security.GeneralSecurityException - if the key generation or the key agreement fails

testECValidateGeneratedKeyPairEncoding

public void testECValidateGeneratedKeyPairEncoding()
                                            throws java.security.GeneralSecurityException

Throws:

java.security.GeneralSecurityException

testInvalidAlgorithm

public void testInvalidAlgorithm()

Ensure invalid algorithm are handled correctly

testUnsupportedEcCurveIsRejected

public void testUnsupportedEcCurveIsRejected()
                                      throws java.lang.Exception

A curve the backend does not support is reported as an InvalidParameterException, not collapsed into a generic failure. The library raises that exception only for the error code the abstraction layer declares for an unsupported parameter.

The companion positive case lives in testECKeyPairGeneration(): a backend that rejected every curve would fail there, so this test does not repeat a generation to guard against it.

Throws:

java.lang.Exception

testUnsupportedRsaKeySizeIsRejected

public void testUnsupportedRsaKeySizeIsRejected()
                                         throws java.lang.Exception

An RSA key size the backend does not support is reported as an InvalidParameterException.

The companion positive case lives in testRSAKeyPairGeneration().

Throws:

java.lang.Exception
