The Tor Project is Now Rewritten in Rust Instead of C

Arti 1.8.0, the Rust rewrite of Tor, introduces circuit timeout improvements that replace predictable timing patterns with randomized intervals to reduce fingerprinting risks. The release includes an experimental command for migrating onion service client authorization keys from C-based Tor to Arti's keystore, plus enhancements to routing architecture and protocol implementation. The rewrite addresses memory safety vulnerabilities inherent in the original C codebase, including buffer overflows and use-after-free bugs.
