### Obtener tus propios datos de usuario

Ahora usa la operación `GET` con la path `/users/me`.

Obtendrás los datos de tu usuario, como:

        byte[] buffer = createBasicNegotiateResponseBuffer();

        // Add a small security buffer at a safe offset (after the fixed structure)
        SMBUtil.writeInt2(64, buffer, 56); // Security buffer offset (relative to header start)
        SMBUtil.writeInt2(8, buffer, 58); // Security buffer length

        // Add some dummy security data at offset 64 from start
        buffer[64] = (byte) 0x4E; // NTLMSSP signature start

## Additional Features { #additional-features }

There are some extra features to handle security apart from the ones covered in the [Tutorial - User Guide: Security](../../tutorial/security/index.md){.internal-link target=_blank}.

/// tip

The next sections are **not necessarily "advanced"**.

And it's possible that for your use case, the solution is in one of them.
