Support Privacy Pass IETF draft as legacy protocol support has been dropped

[StormProductionsMusic]

Describe the bug
I've just installed PrivacyPass on Brave, and it doesn't want to increase my passes, no mater how much challenges I resolve. I resolved 10 challenges already and it still shows 0 passes.

How to reproduce
Steps to reproduce the behavior:

1. Install PrivacyPass on Brave;
2. Resolve a challenge from a supported sie, and see whether your passes are increasing.

Expected behavior
Everytime I solve a challenge, the number of passes should increase and I could redeem them later.

System (please complete the following information):

• OS: Windows
• Cloudflare tokens or hCaptcha tokens? hCaptcha
• Browser: Brave
• Privacy Pass Version: 3.0.6

I can confirm this bug. It's happening the same thing, And it's not even the first time this extension totally breaks . They will fix eventually, but it might take a few weeks. Honestly, I few they should pay more attention to this project :\

Also, just in case, I'm using Firefox Developer 118 on Windows 10.

Yeah, because it doesn't get updated regularly it becomes less effective.

An issue on the service has been identified. A major reshape of the extension is in progress.

Are you part of the team? If so, any clue when this new reshape will be released?

[armfazh]

Unfortunately, it may take few weeks.

An update on the current state of the extension:

A library supporting the latest IETF draft has been released on cloudflare/privacypass-ts, and work on the extension is ongoing.

In the meantime, both Cloudflare and hCaptcha moved on from the original Privacy Pass protocol to the IETF version, in the form of supporting Private Attestation Tokens. This improved interoperability and modularity at the protocol level. In addition, it opened the protocol interface to use cases beyond challenge pass, which this extension focused on. I invite you to check the IETF document to understand how this impacts your use cases.

As progress continues, there should be more news about the extension in early 2024.

[thibmeu]

A fix to this issue is to upgrade to cloudflare/pp-browser-extension.
Both Cloudflare and hCaptcha stopped providing tokens for Privacy Pass in the form it is implemented by the present repository. They both moved to supporting the latest IETF draft.

Cloudflare is committed to continue experimenting with multiple attestations, and has forked the present repository to keep the development going. The fork allows for multiple attesters to be configured on the user side, without requiring a specific provider template at compilation like the present repository.

At the time of writing, there are no attester replicating the behaviour seen in the legacy protocol: pass one challenge, get thirty tokens. Such an attester could be deployed and configured following the attester template.
