Method Detail

engineGeneratePrivate

protected PrivateKey engineGeneratePrivate(KeySpec keySpec)
                                    throws InvalidKeySpecException

Description copied from class: KeyFactorySpi

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

Specified by:

engineGeneratePrivate in class KeyFactorySpi

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.

engineGeneratePublic

protected PublicKey engineGeneratePublic(KeySpec keySpec)
                                  throws InvalidKeySpecException

Description copied from class: KeyFactorySpi

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

Specified by:

engineGeneratePublic in class KeyFactorySpi

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.
