🧅 Arti: Why Tor’s Rust Rewrite Continues to Excite (and the Challenges Ahead)
Short summary
Arti, Tor's Rust rewrite, eliminates memory vulnerabilities of the legacy C daemon while offering modular, embeddable architecture. Core components (protocol, directories, circuits, client API) are available as separate crates. Embedding Arti into Rust applications now takes minutes with clean APIs.
- •Rust eliminates entire classes of memory vulnerabilities inherent to C Tor daemon
- •Arti splits into composable crates, enabling easy embedding into modern apps
- •Simple API reduces integration friction from legacy monolithic Tor client
