Examples of javax.crypto.SecretKeyFactory

javax.crypto.SecretKeyFactory
The public API for {@code SecretKeyFactory} implementations.
Secret key factories provide the following functionality:
- convert {@link SecretKey} objects to and from {@link KeySpec} objects
- translate {@link SecretKey} objects from one provider implementation toanother
Which key specifications are supported by the {@link #generateSecret} and{@link #getKeySpec} is provider dependent.

    KeySpec keySpec = new PBEKeySpec(passCode.toCharArray(), saltValue.getBytes(), 1024, 128);
