This module provides the implementation of Demonstrating Proof-of-Possession (DPoP) as per RFC 9449.

It handles:

• P-256 key pair generation.
• DPoP-signed JWT generation.
• SHA-256 hashing of access tokens for the ath claim.

Structs

DpopKey

An ephemeral P-256 key pair used for signing DPoP proofs.

Functions

dpop_nonce

The DPoP-Nonce response header, if present (RFC 9449 §8.1).
