CLOUDFLARE has open-sourced a new command-line interface tool called **pvcli** for debugging privacy-preserving protocols, specifically **Oblivious HTTP (OHTTP)**. The tool simplifies and streamlines the debugging process that previously required extensive manual effort, reducing it to a single command. pvcli enables users to send OHTTP requests efficiently by managing encryption and binary request formats, making it easier to test and debug privacy protocol implementations.
The tool was developed in response to increasing complexity in managing privacy tools like Privacy Proxy and Privacy Gateway, which have been integrated into services such as Apple’s Private Relay and Microsoft’s VPN. pvcli aims to provide an accessible way to use these protocols, supporting testing, contribution, and future development of other privacy features. Users can install pvcli using Rust and are encouraged to contribute by requesting enhancements or additional functionalities.
