Full-stack encrypted messaging application using lattice-based methods in Rust + PHP + SQL.
This app is meant for educational use.
The encryption methods used have not been hardened against timing attacks or other side-channel attacks.
This code has not been audited for security.
iOS frontend written in Swift: https://github.com/open-encrypt/open-encrypt-ios
A public API is available for performing key generation, encryption, and decryption.
The public API key is open-encrypt-public-api-key. It is currently rate limited to 60 requests / min.
- Documentation: https://docs.open-encrypt.com
- RapidAPI: https://rapidapi.com/jacksonwalters/api/open-encrypt
Currently using Rust binaries ring-lwe v0.1.8 and module-lwe v0.1.5.
- The
pgSQLdatabase and all tables can be initialized with the scriptopen_encrypt_schema_pg.sql. - Passwords are hashed using standard hashing.
- Secure, random tokens stored for user sessions.
- Messages are stored encrypted on the server in a pgSQL table.
- For both ring-LWE and module-LWE, messages are stored as compressed and encoded base64 strings.
Written in PHP. Used to handle basic account creation, login, and SQL insertions/lookups.
