PrivMX Endpoint API Reference

Library written in C++ allowing applications to build E2EE communication channels.

About PrivMX

PrivMX allows developers to build end-to-end encrypted apps used for communication. The Platform works according to privacy-by-design mindset, so all of our solutions are based on Zero-Knowledge architecture. This project extends PrivMX’s commitment to security by making its encryption features accessible to developers using C++.

Key Features

• End-to-End Encryption: Ensures that data is encrypted at the source and can only be decrypted by the intended recipient.
• Native C++ Library Integration: Leverages the performance and security of C++ while making it accessible in C# applications.
• Cross-Platform Compatibility: Designed to support PrivMX on multiple operating systems and environments.
• Simple API: Easy-to-use interface for C# developers without compromising security.

Library

PrivMX Endpoint is the fundamental wrapper library, essential for the Platform’s operational functionality. As the most minimalist library available, it provides the highest degree of flexibility in customizing the Platform to meet your specific requirements.

This library implements models, exception catching, and the following modules:

• privmx::endpoint::crypto::CryptoApi - Cryptographic methods used to encrypt/decrypt and sign your data or generate keys to work with PrivMX.
• privmx::endpoint::core::Connection - Methods for managing connection with PrivMX.
• privmx::endpoint::thread::ThreadApi - Methods for managing Threads and sending/reading messages.
• privmx::endpoint::store::StoreApi - Methods for managing Stores and sending/reading files.
• privmx::endpoint::inbox::InboxApi - Methods for managing Inboxes and entries.
• privmx::endpoint::kvdb::KvdbApi - Methods for managing key-value databeses.
• privmx::endpoint::event::EventApi - Methods for managing custom events.
• privmx::endpoint::stream::StreamApi - Methods for managing Stream Rooms and theirs live Video, Audio and Data Streams.
