Method Detail

engineGeneratePublic

protected PublicKey engineGeneratePublic(KeySpec spec)
                                  throws InvalidKeySpecException

Creates a public key on the HSM from the given key spec. DHPublicKeySpec and X509EncodedKeySpec are supported. The key on the HSM is a temporary session object; use the MakePersistent method to make it permanent.

Specified by:

engineGeneratePublic in class KeyFactorySpi

Parameters:

spec - The specification of the public key to create. This must be an instance of DHPublicKeySpec or X509EncodedKeySpec

Returns:

A public key created on the HSM from the given spec

Throws:

InvalidKeySpecException - If the key spec is of any type other than DHPublicKeySpec or X509EncodedKeySpec, or if the given spec is badly encoded

engineGeneratePrivate

protected PrivateKey engineGeneratePrivate(KeySpec spec)
                                    throws InvalidKeySpecException

Creates a private key on the HSM from the given key spec. Currently only PKCS8EncodedKeySpec is supported. The key on the HSM is a temporary session object; use the MakePersistent method make it permanent.

Specified by:

engineGeneratePrivate in class KeyFactorySpi

Parameters:

spec - The specification of the private key to create. This must be an instance of PKCS8EncodedKeySpec

Returns:

A private key created on the HSM from the given spec

Throws:

InvalidKeySpecException - If the key spec is of any type other than PKCS8EncodedKeySpec, or if the given spec is badly encoded

createLunaKey

protected Key createLunaKey(PublicKey key)

Specified by:

createLunaKey in class LunaKeyFactory

engineTranslateKey

protected Key engineTranslateKey(Key key)
                          throws InvalidKeyException

Description copied from class: LunaKeyFactory

Extracts the specifications of the given public key or private key and returns an instance of LunaPublicKey or LunaPrivateKey. If the incoming key is already an instance of one of those classes, the same key object is returned. If a new key is created on the HSM, it is a temporary session object; use the MakePersistent method to make it permanent.

Overrides:

engineTranslateKey in class LunaKeyFactory

Parameters:

key - The incoming key to translate into a Luna key

Returns:

An instance of a Luna key with the same specifications as the incoming key

Throws:

InvalidKeyException - If the incoming key is not an instance of PublicKey or PrivateKey
