DPoP Proof JWT (RFC 9449) Builder
Build the payload and header of a DPoP proof JWT (RFC 9449) with htm, htu, jti, iat and jwk — for OAuth proof-of-possession tokens.
Spec: RFC 9449. Para assinar, use a chave privada referenciada no jwk. O jti deve ser único por request; iat recente; o ath é o SHA-256 base64url do access_token usado. Esta ferramenta não assina — gera header e payload prontos para sua biblioteca JWT.
