engineGeneratePrivate
Generates a private key object from the provided key specification (key material).- Specified by:
engineGeneratePrivate
in classKeyFactorySpi
- Parameters:
keySpec
- the specification (key material) of the private key (DSAPrivateHWKeySpec is the only accepatble keySpec).- Returns:
- the newly created DSA private key.
- Throws:
InvalidKeySpecException
- if the provided key specification is not appropriate for this key factory to produce a private key.
-
engineGeneratePublic
Generates a public key object from the provided key specification (key material).- Specified by:
engineGeneratePublic
in classKeyFactorySpi
- Parameters:
keySpec
- the specification (key material) of the public key.- Returns:
- the newly created public key.
- Throws:
InvalidKeySpecException
- if the provided key specification is not appropriate for this key factory to produce a public key.
-
engineGetKeySpec
protected <T extends KeySpec> T engineGetKeySpec(Key key, Class<T> keySpecClass) throws InvalidKeySpecException Returns a specification (key material) of the given key in the requested format.- Specified by:
engineGetKeySpec
in classKeyFactorySpi
- Parameters:
key
- the keykeySpecClass
- the requested format in which the key material shall be returned- Returns:
- the underlying key specification (key material) in the requested format
- Throws:
InvalidKeySpecException
- if the requested key specification is inappropriate for the given key, or the given key cannot be processed (e.g., the given key has an unrecognized algorithm or format).
-
engineTranslateKey
Translates aKey
object, whose provider may be unknown or potentially untrusted, into a correspondingKey
object of this key factory.- Specified by:
engineTranslateKey
in classKeyFactorySpi
- Parameters:
key
- the key whose provider is unknown or untrusted- Returns:
- the translated key
- Throws:
InvalidKeyException
- if the given key cannot be processed by this key factory.
