defmodule SkillKit.Webhook.Verifier.Stripe do

  @moduledoc """

  Stripe webhook signature verifier.



  Delegates to `SkillKit.Webhook.Verifier.Hmac` with Stripe's well-known

  scheme baked in: HMAC-SHA256 over `"<timestamp>.<body>"`, with both the

  timestamp and the signature pulled from the `Stripe-Signature` header.



  ## Registration config (passed through)



  - `secret_key` (required) — the key name resolved via `CredentialProvider`.

  - `max_skew` (optional) — timestamp tolerance in seconds. Default 300.
