The functions detailed in this section are low-level, and implement specific algorithms.
They are only designed to be used as building blocks for custom constructions, or for interoperability with other libraries and applications.
As a result, using these functions directly may not be secure if not done correctly.
The behavior and/or interface of these functions can change at any point in time.
Low-level functions that are not required by high-level APIs are also not present in libsodium when compiled in minimal mode.
Unless you absolutely need these specific algorithms, use the high-level APIs whenever possible.
Bindings for 3rd party languages are encouraged to use the high-level APIs as well. The underlying functions they depend on is guaranteed to never change without a major bump of the library version.
