Method Detail

generatePublic

public PublicKey generatePublic(KeySpec keySpec)
                         throws InvalidKeySpecException

Converts, if possible, a key specification into a GMSSPublicKey. Currently the following key specs are supported: GMSSPublicKeySpec, X509EncodedKeySpec.

Overrides:

generatePublic in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

A GMSS public key

Throws:

InvalidKeySpecException - if the KeySpec is not supported

generatePrivate

public PrivateKey generatePrivate(KeySpec keySpec)
                           throws InvalidKeySpecException

Converts, if possible, a key specification into a GMSSPrivateKey. Currently the following key specs are supported: GMSSPrivateKeySpec.

Overrides:

generatePrivate in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

The GMSS private key

Throws:

InvalidKeySpecException - if the KeySpec is not supported

See Also:

GMSSPrivateKey, GMSSPrivateKeySpec

getKeySpec

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

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

• for GMSSPublicKey: X509EncodedKeySpec, GMSSPublicKeySpec
• for GMSSPrivateKey: PKCS8EncodedKeySpec, GMSSPrivateKeySpec

Overrides:

getKeySpec in class KeyFactory

Parameters:

key - the key

spec - the class of which type the returned class should be

Returns:

The specification of the GMSS key

Throws:

InvalidKeySpecException - if the specification is not supported

GMSSPrivateKey, GMSSPrivateKeySpec, GMSSPublicKey, GMSSPublicKeySpec

translateKey

public Key translateKey(Key key)
                 throws InvalidKeyException

Translates a key into a form known by the FlexiProvider. Currently the following key types are supported: GMSSPrivateKey, GMSSPublicKey.

Overrides:

translateKey in class KeyFactory

Parameters:

key - the key

Returns:

A key of a known key type

Throws:

InvalidKeyException - if the key is not supported
