Pkce class

RFC 7636 Proof Key for Code Exchange (S256).

Mobile apps are public OAuth clients (no secret), so PKCE is mandatory. The verifier stays on-device; the challenge is sent to /oauth/authorize.

Constructors

Pkce.fromVerifier(String verifier)

Build a pair from an existing verifier (used by tests with RFC vectors).

factory

Pkce.generate()

Generate a fresh, verifiable verifier + S256 challenge.
