    LOW LEVEL API'S

    Low level API;s expose the functions for the specific primitives, and
    support some functions that are only included for legacy reasons.

    Some functions are aliased by the higher-level API calls, and should produce
    the exact same result when called. For compatibility reasons, the primitive-
    specific function calls are implemented and wrapped seperately, so when a
    primitive changes in the official Sodium library, it automatically changes
    in libstodium as well.

    The Low-level implementations are exported for the sake of completeness, as
    well as the primitive-specific implementations of the Java standard
    interfaces for cryptographic operations.
