Relay and target for Oblivious DoH (ODoH) and ODoH-based Mutualized Oblivious DNS (ODoH-based μODNS; μODoH) supporting (anonymous) authenticated connection, written in Rust.

Auditably privacy-preserving age verification with RFC 9474 RSA blind signatures. A relying party learns only the age predicate (over-13/18/…); the issuer never sees the nonce, token, or site; unlinkability is verifiable, not promised. Python uv workspace. Research prototype — unaudited.

Browser-based blind signature demo — Chaum RSA blind signatures, Schnorr EC blind signatures, anonymous e-cash, private voting, and unlinkability proofs. No backends. No simulated math.
