Interface KeyLoader

  • All Known Implementing Classes:
    ECDSAKeyLoader, RSAKeyLoader, SunECKeyLoader
    public interface KeyLoader
    The KeyLoader interface is used internally by BFT-SMaRt to load signature keys from disk. Developers can use implementations of this interface so that if their application uses key structures similar to the library, these keys can be shared by both the library and the application to simplify key management.
