#### Declaration [src]

    void
    gck_session_verify_async (
      GckSession* self,
      GckObject* key,
      GckMechanism* mechanism,
      const guchar* input,
      gsize n_input,
      const guchar* signature,
      gsize n_signature,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

Verify data in a mechanism specific manner. This call returns immediately and completes asynchronously.

This method completes asynchronously. Use `gck_session_verify_finish()` inside the `GAsyncReadyCallback` to obtain the result of the operation.
