Method Detail

generatePublic

public PublicKey generatePublic(KeySpec keySpec)
                         throws InvalidKeySpecException

Converts, if possible, a key specification into a NiederreiterPublicKey. Currently, the following key specifications are supported: NiederreiterPublicKeySpec.

Overrides:

generatePublic in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

the public Niederreiter key

Throws:

InvalidKeySpecException - if the KeySpec is not supported.

NiederreiterPublicKey, NiederreiterPublicKeySpec

generatePrivate

public PrivateKey generatePrivate(KeySpec keySpec)
                           throws InvalidKeySpecException

Converts, if possible, a key specification into a NiederreiterPrivateKey. Currently, the following key specifications are supported: NiederreiterPrivateKeySpec.

Overrides:

generatePrivate in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

the private Niederreiter key

Throws:

InvalidKeySpecException - if the KeySpec is not supported.

NiederreiterPrivateKey, NiederreiterPrivateKeySpec

getKeySpec

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

Converts, if possible, a given key into a key specification. Currently, the following specifications are supported:

• for NiederreiterPublicKey: X509EncodedKeySpec, NiederreiterPublicKeySpec
• for NiederreiterPrivateKey: PKCS8EncodedKeySpec, NiederreiterPrivateKeySpec

Overrides:

getKeySpec in class KeyFactory

Parameters:

key - the key

keySpec - the class of which type the returned class should be.

Returns:

the specification of the Niederreiter key

Throws:

InvalidKeySpecException - if the key type or key specification is not supported.

translateKey

public Key translateKey(Key key)
                 throws InvalidKeyException

Translates a key into a form known by the FlexiProvider. Currently the following "source" keys are supported: NiederreiterPrivateKey, NiederreiterPublicKey.

Overrides:

translateKey in class KeyFactory

Parameters:

key - the key

Returns:

a key of a known key type

Throws:

InvalidKeyException - if the key type is not supported.
