Usually it's impossible to create a Olm session from a pre-key message twice. The one-time key that should be used for the 3DH step will be used up and we're going to throw a `MissingOneTimeKey` error. This used to be true and unproblematic until we added fallback keys, these keys will not get discarded immediately after they have been used once. This means that a pre-key message, for which we already have a Session, but decryption for it fails, might create a new Session overwriting the existing one which will essentially reset the ratchet.
matrix-rust-sdk
matrix-rust-sdk is an implementation of a Matrix client-server library in Rust.
Project structure
The rust-sdk consists of multiple crates that can be picked at your convenience:
- matrix-sdk - High level client library, with batteries included, you're most likely interested in this.
- matrix-sdk-base - No (network) IO client state machine that can be used to embed a Matrix client in your project or build a full fledged network enabled client lib on top of it.
- matrix-sdk-crypto - No (network) IO encryption state machine that can be used to add Matrix E2EE support to your client or client library.
Minimum Supported Rust Version (MSRV)
These crates are built with the Rust language version 2021 and require a minimum compiler version of 1.70.
Status
The library is in an alpha state, things that are implemented generally work but the API will change in breaking ways.
If you are interested in using the matrix-sdk now is the time to try it out and provide feedback.
Bindings
Some crates of the matrix-rust-sdk can be embedded inside other
environments, like Swift, Kotlin, JavaScript, Node.js etc. Please,
explore the bindings/ directory to learn more.
