Class KeyFactoryTest

java.lang.Object

com.microej.crypto.test.KeyFactoryTest

public class KeyFactoryTest
extends java.lang.Object

This test class can be used to validate a KeyFactory low-level implementation.

Currently, only the ECPublicKeyNamedCurveSpec parameter is tested.

Method Summary

Modifier and Type	Method	Description
void	testExportPrivateKeyToPkcs8()
void	testGeneratePrivateRejectsInvalidEncoding()	Encoded private key bytes the backend cannot decode are reported with the checked exception the JCA declares, not with a runtime exception an Application following the JCA contract would not catch.
void	testGeneratePublicKeyFromECNamedCurveAndAffineCoordinates()
void	testGeneratePublicRejectsInvalidEncoding()	Encoded public key bytes the backend cannot decode are reported with the checked exception the JCA declares.
void	testGeneratePublicRejectsUnknownCurve()	A named-curve public key spec the backend cannot use is reported with the checked exception the JCA declares.
void	testPrivateKeyGetEncodedReturnsDefensiveCopy()	Verifies that the PrivateKey returned by a KeyFactory hands back a fresh defensive copy from Key.getEncoded() on every call, so a caller that mutates the returned array cannot corrupt the key's cached encoding.
void	testPublicKeyGetEncodedReturnsDefensiveCopy()	Verifies that the PublicKey returned by a KeyFactory hands back a fresh defensive copy from Key.getEncoded() on every call, so a caller that mutates the returned array cannot corrupt the key's cached encoding.

Method Detail

testExportPrivateKeyToPkcs8

public void testExportPrivateKeyToPkcs8()
                                 throws java.lang.Exception

Throws:

java.lang.Exception

testGeneratePublicKeyFromECNamedCurveAndAffineCoordinates

public void testGeneratePublicKeyFromECNamedCurveAndAffineCoordinates()
                                                               throws java.lang.Exception

Throws:

java.lang.Exception

testGeneratePrivateRejectsInvalidEncoding

public void testGeneratePrivateRejectsInvalidEncoding()
                                               throws java.lang.Exception

Encoded private key bytes the backend cannot decode are reported with the checked exception the JCA declares, not with a runtime exception an Application following the JCA contract would not catch.

Throws:

java.lang.Exception

testGeneratePublicRejectsInvalidEncoding

public void testGeneratePublicRejectsInvalidEncoding()
                                              throws java.lang.Exception

Encoded public key bytes the backend cannot decode are reported with the checked exception the JCA declares.

Throws:

java.lang.Exception

testGeneratePublicRejectsUnknownCurve

public void testGeneratePublicRejectsUnknownCurve()
                                           throws java.lang.Exception

A named-curve public key spec the backend cannot use is reported with the checked exception the JCA declares.

An unknown curve name is used rather than coordinates off the curve: not every backend checks that the point lies on the curve when importing it.

Throws:

java.lang.Exception

testPrivateKeyGetEncodedReturnsDefensiveCopy

public void testPrivateKeyGetEncodedReturnsDefensiveCopy()
                                                  throws java.lang.Exception

Verifies that the PrivateKey returned by a KeyFactory hands back a fresh defensive copy from Key.getEncoded() on every call, so a caller that mutates the returned array cannot corrupt the key's cached encoding.

Throws:

java.lang.Exception

testPublicKeyGetEncodedReturnsDefensiveCopy

public void testPublicKeyGetEncodedReturnsDefensiveCopy()
                                                 throws java.lang.Exception

Verifies that the PublicKey returned by a KeyFactory hands back a fresh defensive copy from Key.getEncoded() on every call, so a caller that mutates the returned array cannot corrupt the key's cached encoding.

Throws:

java.lang.Exception
