engineGetKeySpec	back to summary
protected KeySpec engineGetKeySpec(Key key, Class<T> tClass) 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. Parameters key:Key the key. tClass:Class<T> the specification class in which the key material should be returned. Returns:KeySpec the underlying key specification (key material) in an instance of the requested specification 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).

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

Implements abstract java.security.KeyFactorySpi.engineGetKeySpec.

Doc from java.security.KeyFactorySpi.engineGetKeySpec.

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:Key: the key.
tClass:Class<T>: the specification class in which the key material should be returned.

Returns:KeySpec

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