[Privacy-pass] Typescript implementation of Privacy Pass components

[Thibault Meunier <[e-mail]>]

Hi Privacy Pass WG,

This is to inform the group of the availability of TypeScript-based implementation of components defined by the architecture document.

You can find the source code on GitHub on the following projects: pp-origin [1], pp-browser-extension [2], pp-attester [3], and pp-issuer [4]. Each of these components can be deployed separately, offering flexibility for experimentation and setup. A helper tool is provided to this end: pp-config [5].

It is worth noting that pp-browser-extension is a client designed to work with pp-attester. Their interaction is defined on their respective repositories, as it is not part of standardised documents. Specifically, the extension introduces a client API for request replay, and the attester proposes an HTTP API, allowing multiple attesters to be used by a single client. Implementing the proposed HTTP mirror draft [6] could be a path forward here.

We hope you will find these implementations valuable for your needs. Please don't hesitate to reach out if you encounter any issues or have any feedback. Your input is highly appreciated.

Best,

Thibault Meunier
