Method Detail

generatePublic

public PublicKey generatePublic(KeySpec keySpec)
                         throws InvalidKeySpecException

Converts, if possible, a key specification into a McEliecePublicKey. Currently, the following key specifications are supported: McEliecePublicKeySpec, X509EncodedKeySpec.

Overrides:

generatePublic in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

the McEliece public key

Throws:

InvalidKeySpecException - if the key specification is not supported.

generatePrivate

public PrivateKey generatePrivate(KeySpec keySpec)
                           throws InvalidKeySpecException

Converts, if possible, a key specification into a McEliecePrivateKey. Currently, the following key specifications are supported: McEliecePrivateKeySpec, PKCS8EncodedKeySpec.

Overrides:

generatePrivate in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

the McEliece private key

Throws:

InvalidKeySpecException - if the KeySpec is not supported.

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 key specifications are supported:

• for McEliecePublicKey: X509EncodedKeySpec, McEliecePublicKeySpec
• for McEliecePrivateKey: PKCS8EncodedKeySpec, McEliecePrivateKeySpec
.

Overrides:

getKeySpec in class KeyFactory

Parameters:

key - the key

keySpec - the key specification

Returns:

the specification of the McEliece key

Throws:

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

McEliecePrivateKey, McEliecePrivateKeySpec, McEliecePublicKey, McEliecePublicKeySpec

translateKey

public Key translateKey(Key key)
                 throws InvalidKeyException

Translates a key into a form known by the FlexiProvider. Currently, only the following "source" keys are supported: McEliecePrivateKey, McEliecePublicKey.

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.
