## Der `password`-Flow { #the-password-flow }

Lassen Sie uns nun etwas zurückgehen und verstehen, was das alles ist.

Der `password`-„Flow“ ist eine der in OAuth2 definierten Wege („Flows“) zur Handhabung von Sicherheit und Authentifizierung.

            throw new IllegalArgumentException("Password hash must be provided, expected length 16 byte");
        }
        this.ntHash = passwordHash;
    }

    /**
     * Create username/password credentials with specified domain
     *
     * @param domain the authentication domain
     * @param username the username
     * @param passwordHashHex
     *            NT password hash, hex encoded
     */

Um dies zu lösen, konvertieren wir zunächst den `username` und das `password` in UTF-8-codierte `bytes`.

Dann können wir `secrets.compare_digest()` verwenden, um sicherzustellen, dass `credentials.username` `"stanleyjobson"` und `credentials.password` `"swordfish"` ist.

Dies wäre das gleiche wie:

```Python

import okhttp3.internal.platform.Platform
import okhttp3.tls.HandshakeCertificates
import okhttp3.tls.HeldCertificate
import org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

object TlsUtil {
  val password = "password".toCharArray()

  private val localhost: HandshakeCertificates by lazy {
    // Generate a self-signed cert for the server to serve and the client to trust.
    val heldCertificate =
      HeldCertificate

будет эквивалентно:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Или, более точно, если использовать `user_dict` напрямую, с любым содержимым, которое он может иметь в будущем:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],

Resultaria em algo equivalente a:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Ou mais exatamente, usando `user_dict` diretamente, com qualquer conteúdo que ele possa ter no futuro:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)

為了處理這點，我們會先將 `username` 與 `password` 以 UTF-8 編碼成 `bytes`。

接著我們可以使用 `secrets.compare_digest()` 來確認 `credentials.username` 等於 `"stanleyjobson"`，而 `credentials.password` 等於 `"swordfish"`。

{* ../../docs_src/security/tutorial007_an_py310.py hl[1,12:24] *}

這大致等同於：

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # 回傳錯誤
    ...
```

		if err != nil {
			os.Remove(privateKey)
			t.Fatalf("Test %d: failed to create tmp certificate file: %v", i, err)
		}

		if testCase.password != "" {
			t.Setenv(EnvCertPassword, testCase.password)
		}
		_, err = LoadX509KeyPair(certificate, privateKey)
		if err != nil && !testCase.shouldFail {
			t.Errorf("Test %d: test should succeed but it failed: %v", i, err)
		}

        return "Secure console password prompt";
    }

    @Override
    public Optional<String> configTemplate() {
        return Optional.empty();
    }

    @Override
    public String handle(String config) throws SecDispatcherException {
        if (NAME.equals(config)) {
            try {
                return prompter.promptForPassword("Enter the master password: ");
            } catch (PrompterException e) {

	Endpoint   string
	rootCAs    *x509.CertPool
	username   string
	password   string
}

// OperatorOption - functional options pattern style for OperatorDNS
type OperatorOption func(*OperatorDNS)

// Authentication - custom username and password for authenticating at the endpoint
func Authentication(username, password string) OperatorOption {
	return func(args *OperatorDNS) {
		args.username = username
