Method Details

engineGeneratePublic

protected PublicKey engineGeneratePublic(KeySpec keySpec)
                                  throws InvalidKeySpecException

Converts, if possible, a key specification into a BCMcElieceCCA2PublicKey. Currently, the following key specifications are supported: X509EncodedKeySpec.

Specified by:

engineGeneratePublic in class KeyFactorySpi

Parameters:

keySpec - the key specification

Returns:

the McEliece CCA2 public key

Throws:

InvalidKeySpecException - if the key specification is not supported.

engineGeneratePrivate

protected PrivateKey engineGeneratePrivate(KeySpec keySpec)
                                    throws InvalidKeySpecException

Converts, if possible, a key specification into a BCMcElieceCCA2PrivateKey. Currently, the following key specifications are supported: PKCS8EncodedKeySpec.

Specified by:

engineGeneratePrivate in class KeyFactorySpi

Parameters:

keySpec - the key specification

Returns:

the McEliece CCA2 private key

Throws:

InvalidKeySpecException - if the KeySpec is not supported.

getKeySpec

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

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

Parameters:

key - the key

keySpec - the key specification

Returns:

the specification of the McEliece CCA2 key

Throws:

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

• BCMcElieceCCA2PrivateKey
• BCMcElieceCCA2PublicKey

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: BCMcElieceCCA2PrivateKey, BCMcElieceCCA2PublicKey.

Parameters:

key - the key

Returns:

a key of a known key type

Throws:

InvalidKeyException - if the key type is not supported.
