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

Doc from java.security.KeyFactorySpi.engineGeneratePublic.

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

Annotations
@Override
Exceptions
InvalidKeySpecException:
if the given key specification is inappropriate for this key factory to produce a public key.

protected <T extends KeySpec> T engineGetKeySpec(Key key, Class<T> keySpec) throws InvalidKeySpecException

Implements abstract java.security.KeyFactorySpi.engineGetKeySpec.

Doc from java.security.KeyFactorySpi.engineGetKeySpec.

Returns 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.

Exceptions
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).
engineTranslateKeyback to summary
protected Key engineTranslateKey(Key key) throws InvalidKeyException

Implements abstract java.security.KeyFactorySpi.engineTranslateKey.

Doc from java.security.KeyFactorySpi.engineTranslateKey.

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

Annotations
@Override
Exceptions
InvalidKeyException:
if the given key cannot be processed by this key factory.
