# privacypass-ts: A TypeScript Library for the Privacy Pass Issuance Protocol

**Specification:** Compliant with IETF [draft-ietf-privacypass-protocol](https://datatracker.ietf.org/doc/draft-ietf-privacypass-protocol/), [draft-hendrickson-privacypass-public-metadata-03](https://datatracker.ietf.org/doc/draft-hendrickson-privacypass-public-metadata/) and tests vectors match with draft [v11](https://datatracker.ietf.org/doc/draft-ietf-privacypass-protocol/11/).

**Support:**

 - Public-Verifiable tokens (Blind-RSA)

 - Public-Verifiable tokens with Metadata (Partially-Blind-RSA)

 - Private-Verifiable tokens (VOPRF)

**Usage:**

We provide examples in the [examples folder](examples).

### Limitations

- Public-Verifiable tokens with Metadata verification is not supported in browser environments. This is due to @cloudflare/blindrsa-ts [not supporting them](https://github.com/cloudflare/blindrsa-ts?tab=readme-ov-file#platform-specific-configuration).
