Щоб це обійти, ми спочатку перетворюємо `username` і `password` у `bytes`, кодувавши їх у UTF-8.

Потім ми можемо використати `secrets.compare_digest()`, щоб упевнитися, що `credentials.username` дорівнює `"stanleyjobson"`, а `credentials.password` дорівнює `"swordfish"`.

Це було б подібно до:

        assertEquals("\\2a\\29\\28uid=\\2a\\29\\29\\28|\\28uid=\\2a", LdapUtil.escapeValue("*)(uid=*))(|(uid=*"));

        // Test complex injection: admin)(&(password=*))
        assertEquals("admin\\29\\28&\\28password=\\2a\\29\\29", LdapUtil.escapeValue("admin)(&(password=*))"));
    }

    @Test
    public void test_escapeValue_allSpecialCharsInSequence() {
        assertEquals("\\5c\\2a\\28\\29\\00", LdapUtil.escapeValue("\\*()\0"));

Now, whenever a browser is creating a user with a password, the API will return the same password in the response.

In this case, it might not be a problem, because it's the same user sending the password.

But if we use the same model for another *path operation*, we could be sending our user's passwords to every client.

/// danger

    public void setPassword_Terms(ConditionOptionCall<TermsAggregationBuilder> opLambda) {
        setPassword_Terms("password", opLambda, null);
    }

    public void setPassword_Terms(ConditionOptionCall<TermsAggregationBuilder> opLambda, OperatorCall<BsWebAuthenticationCA> aggsLambda) {
        setPassword_Terms("password", opLambda, aggsLambda);
    }

        assertEquals("********", SystemUtil.maskSensitiveValue("password", "secret"));
        assertEquals("********", SystemUtil.maskSensitiveValue("PASSWORD", "secret"));
        assertEquals("********", SystemUtil.maskSensitiveValue("Password", "secret"));
        assertEquals("********", SystemUtil.maskSensitiveValue("PaSsWoRd", "secret"));
    }

    @Test
    public void test_maskSensitiveValue_emptyValue() {

	contentType := r.Header.Get("Content-Type")
	if contentType != "application/octet-stream" {
		writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrBadRequest), r.URL)
		return
	}

	password := cred.SecretKey
	reqBytes, err := madmin.DecryptData(password, io.LimitReader(r.Body, r.ContentLength))
	if err != nil {
		adminLogIf(ctx, err)
		writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrAdminConfigBadJSON), r.URL)
		return
	}

UserInDB(**user_dict)
```

以下と同等の結果になります:

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

もっと正確に言えば、`user_dict`を将来的にどんな内容であっても直接使用することになります:

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

            final String username = userCredential.getUser();
            final String password = userCredential.getPassword();
            if (!fessConfig.isAdminUser(username)) {
                final OptionalEntity<FessUser> ldapUser = ComponentUtil.getLdapManager().login(username, password);
                if (ldapUser.isPresent()) {
                    return ldapUser;
                }
            }

为了解决这个问题，我们首先将 `username` 和 `password` 转换为使用 UTF-8 编码的 `bytes` 。

然后我们可以使用 `secrets.compare_digest()` 来确保 `credentials.username` 是 `"stanleyjobson"`，且 `credentials.password` 是`"swordfish"`。

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

这类似于：

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Return some error
    ...
```
