Create a Privacy Pass

Issues a Privacy Pass token by blind-signing a client-provided blinded token (Blind RSA, RFC 9578). The returned blind signature is unblinded client-side to produce a Privacy Pass token that can later be redeemed anonymously (for example, when generating a Relay claim).

Authentication
