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.

Examples of unacceptable behavior by participants include:

*   The use of sexualized language or imagery and unwelcome sexual attention or
    advances.
*   Trolling, insulting/derogatory comments, and personal or political attacks.
*   Public or private harassment.
*   Publishing others' private information, such as a physical or electronic
    address, without explicit permission.

     * vulnerable to man-in-the-middle attacks and should only be used only in private development
     * environments and only to carry test data.
     *
     * The server’s TLS certificate **does not need to be signed** by a trusted certificate

 * authorities either known or unknown to the application's user.

The *Secure Channel* splits the object content into chunks of a fixed size of `65536` bytes. The last chunk may be smaller to avoid adding additional overhead and is treated specially to prevent truncation attacks. The nonce value is 96 bits long and generated randomly per object / multi-part part. The *Secure Channel* supports plaintexts up to `65536 * 2^32 = 256 TiB`.
