Method Detail

engineGeneratePublic

protected java.security.PublicKey engineGeneratePublic(java.security.spec.KeySpec keySpec)
                                                throws java.security.spec.InvalidKeySpecException

JCA adapter for FlexiAPI method generatePublic(): generates a public key object from the provided key specification (key material).

Overrides:

engineGeneratePublic in class java.security.KeyFactorySpi

Parameters:

keySpec - the specification (key material) of the public key

Returns:

the public key

Throws:

java.security.spec.InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a public key.

engineGeneratePrivate

protected java.security.PrivateKey engineGeneratePrivate(java.security.spec.KeySpec keySpec)
                                                  throws java.security.spec.InvalidKeySpecException

JCA adapter for FlexiAPI method generatePrivate(): generate a private key object from the provided key specification (key material).

Overrides:

engineGeneratePrivate in class java.security.KeyFactorySpi

Parameters:

keySpec - the specification (key material) of the private key

Returns:

the private key

Throws:

java.security.spec.InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a private key.

engineGetKeySpec

protected final java.security.spec.KeySpec engineGetKeySpec(java.security.Key key,
                                                            java.lang.Class keySpec)
                                                     throws java.security.spec.InvalidKeySpecException

JCA adapter for FlexiAPI method getKeySpec(): return a specification (key material) of the given key object. keySpec identifies the specification class in which the key material should be returned. It could, for example, be DSAPublicKeySpec.class, to indicate that the key material should be returned in an instance of the DSAPublicKeySpec class.

Overrides:

engineGetKeySpec in class java.security.KeyFactorySpi

Parameters:

key - the key

keySpec - the specification class in which the key material should be returned

Returns:

the underlying key specification (key material) in an instance of the requested specification class

Throws:

java.security.spec.InvalidKeySpecException - if the requested key specification is inappropriate for the given key, or the given key cannot be dealt with (e.g., the given key has an unrecognized format).

engineTranslateKey

protected final java.security.Key engineTranslateKey(java.security.Key key)
                                              throws java.security.InvalidKeyException

JCA adapter for FlexiAPI method translateKey(): translate a key object, whose provider may be unknown or potentially untrusted, into a corresponding key object of this key factory.

Overrides:

engineTranslateKey in class java.security.KeyFactorySpi

Parameters:

key - the key whose provider is unknown or untrusted

Returns:

the translated key

Throws:

java.security.InvalidKeyException - if the given key cannot be processed by this key factory.

generatePublic

public abstract PublicKey generatePublic(KeySpec keySpec)
                                  throws InvalidKeySpecException

Generate a public key object from the provided key specification (key material).

Parameters:

keySpec - the specification (key material) of the public key

Returns:

the public key

Throws:

InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a public key.

generatePrivate

public abstract PrivateKey generatePrivate(KeySpec keySpec)
                                    throws InvalidKeySpecException

Generate a private key object from the provided key specification (key material).

Parameters:

keySpec - the specification (key material) of the private key

Returns:

the private key

Throws:

InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a private key.

getKeySpec

public abstract KeySpec getKeySpec(Key key,
                                   java.lang.Class keySpec)
                            throws InvalidKeySpecException

Return a specification (key material) of the given key object. keySpec identifies the specification class in which the key material should be returned. It could, for example, be DSAPublicKeySpec.class, to indicate that the key material should be returned in an instance of the DSAPublicKeySpec class.

Parameters:

key - the key

keySpec - the specification class in which the key material should be returned

Returns:

the underlying key specification (key material) in an instance of the requested specification class

Throws:

InvalidKeySpecException - if the requested key specification is inappropriate for the given key, or the given key cannot be dealt with (e.g., the given key has an unrecognized format).

translateKey

public abstract Key translateKey(Key key)
                          throws InvalidKeyException

Translate a key object, whose provider may be unknown or potentially untrusted, into a corresponding key object of this key factory.

Parameters:

key - the key whose provider is unknown or untrusted

Returns:

the translated key

Throws:

InvalidKeyException - if the given key cannot be processed by this key factory.
