Method Detail

generatePublic

public PublicKey generatePublic(KeySpec keySpec)
                         throws InvalidKeySpecException

Overrides:

generatePublic in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

a public Merkle OTS 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 MerkleOTSPrivateKey. Currently, the following key specifications are supported: MerkleOTSPrivateKeySpec.

Overrides:

generatePrivate in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

a private Merkle OTS key

Throws:

InvalidKeySpecException - if the KeySpec is not supported.

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 specifications are supported:

• for MerkleOTSPublicKey: X509EncodedKeySpec, OTSKeySpec
• for OTSPrivateKey: PKCS8EncodedKeySpec, OTSKeySpec.

Overrides:

getKeySpec in class KeyFactory

Parameters:

key - the key.

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

Returns:

OTSKeySpec the specification of the MerkleOTS key.

Throws:

InvalidKeySpecException - if the 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: OTSPrivateKey, MerkleOTSPublicKey.

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.
