The authentication flow is similar to that of OpenID, however the token is "opaque" to MinIO - it is simply sent to the plugin for verification. CAVEAT: There is no console UI integration for this method of authentication and it is intended primarily for machine authentication.

a Go translation.  C arithmetic types translate to precisely-sized Go
arithmetic types.  A C struct translates to a Go struct, field by
field; unrepresentable fields are replaced with opaque byte arrays.  A
C union translates into a struct containing the first union member and
perhaps additional padding.  C arrays become Go arrays.  C pointers
become Go pointers.  C function pointers become Go's uintptr.

        // Act: len==0 triggers initial token construction
        byte[] out = ctx.initSecContext(null, 0, 0);

        // Assert: returns a SPNEGO token (opaque here but non-null/non-empty)
        assertNotNull(out);
        assertTrue(out.length > 0);

        // Verify interactions: flags and an empty optimistic token are used
        verify(this.mechContext, times(1)).getFlags();

Porém, ao utilizar o `secrets.compare_digest()`, isso estará seguro contra um tipo de ataque chamado "timing attacks" (ataques de temporização).

### Ataques de Temporização

Mas o que é um "timing attack" (ataque de temporização)?

Vamos imaginar que alguns invasores estão tentando adivinhar o usuário e a senha.

```Python
if "johndoe" == "stanleyjobson" and "love123" == "swordfish":
    ...
```

Pero justo en el momento en que Python compara la primera `j` en `johndoe` con la primera `s` en `stanleyjobson`, devolverá `False`, porque ya sabe que esas dos strings no son iguales, pensando que "no hay necesidad de gastar más computación comparando el resto de las letras". Y tu aplicación dirá "Nombre de usuario o contraseña incorrectos".
