engineGeneratePrivate
protected java.security.PrivateKey engineGeneratePrivate(java.security.spec.KeySpec keySpec) throws java.security.spec.InvalidKeySpecException
Generates a private key object from the provided key specification (key material).- Specified by:
engineGeneratePrivate
in classjava.security.KeyFactorySpi
- Parameters:
keySpec
- the specification (key material) of the private key (DSAPrivateHWKeySpec is the only accepatble keySpec).- Returns:
- the newly created DSA private key.
- Throws:
java.security.spec.InvalidKeySpecException
- if the provided key specification is not appropriate for this key factory to produce a private key.
-
engineGeneratePublic
protected java.security.PublicKey engineGeneratePublic(java.security.spec.KeySpec keySpec) throws java.security.spec.InvalidKeySpecException
Generates a public key object from the provided key specification (key material).- Specified by:
engineGeneratePublic
in classjava.security.KeyFactorySpi
- Parameters:
keySpec
- the specification (key material) of the public key.- Returns:
- the newly created public key.
- Throws:
java.security.spec.InvalidKeySpecException
- if the provided key specification is not appropriate for this key factory to produce a public key.
-
engineGetKeySpec
protected java.security.spec.KeySpec engineGetKeySpec(java.security.Key key, java.lang.Class keySpecClass) throws java.security.spec.InvalidKeySpecException
Returns a specification (key material) of the given key in the requested format.- Specified by:
engineGetKeySpec
in classjava.security.KeyFactorySpi
- 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:
java.security.spec.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
protected java.security.Key engineTranslateKey(java.security.Key key) throws java.security.InvalidKeyException
Translates aKey
object, whose provider may be unknown or potentially untrusted, into a correspondingKey
object of this key factory.- Specified by:
engineTranslateKey
in classjava.security.KeyFactorySpi
- Parameters:
key
- the key whose provider is unknown or untrusted- Returns:
- the translated key
- Throws:
java.security.InvalidKeyException
- if the given key cannot be processed by this key factory.
