Method Detail

generatePublic

public final PublicKey generatePublic(KeySpec keySpec)
                               throws InvalidKeySpecException

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

Overrides:

generatePublic in class KeyFactory

Parameters:

keySpec - the key specification

Returns:

a CMSS2 public key

Throws:

InvalidKeySpecException - if the KeySpec is not supported.

generatePrivate

public final PrivateKey generatePrivate(KeySpec keySpec)
                                 throws InvalidKeySpecException

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

Overrides:

generatePrivate in class KeyFactory

Parameters:

keySpec - - the key specification

Returns:

a CMSS2 private key

Throws:

InvalidKeySpecException - if the KeySpec is not supported.

getKeySpec

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

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

• for CMSSPublicKey: X509EncodedKeySpec, CMSSPublicKeySpec
• for CMSSPrivateKey: PKCS8EncodedKeySpec, CMSSPrivateKeySpec

Overrides:

getKeySpec in class KeyFactory

Parameters:

key - the key

keySpec - the key specification

Returns:

the specification of the CMSS2 key

Throws:

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

translateKey

public final Key translateKey(Key key)
                       throws InvalidKeyException

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

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.
