# Advanced The functions outlined in this section are low-level and implement specific algorithms. They are only designed to be used as building blocks for custom constructions or 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 need these specific algorithms, use the high-level APIs when possible. Bindings for third-party languages are encouraged to use the high-level APIs as well. The underlying functions they depend on are guaranteed to never change without a major version bump of the library. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://libsodium.gitbook.io/doc/advanced.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
