Protected Methods

protected abstract PrivateKey engineGeneratePrivate (KeySpec keySpec)

Added in API level 1

Generates a instance of PrivateKey from the given key specification.

Parameters

keySpec	the specification of the private key.

Returns

the private key.

Throws

InvalidKeySpecException	if the specified `keySpec` is invalid.

protected abstract PublicKey engineGeneratePublic (KeySpec keySpec)

Added in API level 1

Generates a instance of PublicKey from the given key specification.

Parameters

keySpec	the specification of the public key.

Returns

the public key.

Throws

InvalidKeySpecException	if the specified `keySpec` is invalid.

Added in API level 1

Returns the key specification for the specified key.

Parameters

key	the key from which the specification is requested.
keySpec	the type of the requested `KeySpec`.

Returns

the key specification for the specified key.

Throws

InvalidKeySpecException	if the key can not be processed, or the requested requested `KeySpec` is inappropriate for the given key.

protected abstract Key engineTranslateKey (Key key)

Added in API level 1

Translates the given key into a key from this key factory.

Parameters

key	the key to translate.
