/**
 * Provides the API for the Maven Password Encryption tool ({@code mvnenc}).
 *
 * <p>This package contains interfaces and classes for the password encryption tool,
 * which helps secure sensitive information in Maven settings and configuration files.</p>
 *
 * <p>Key features include:</p>
 * <ul>
 *   <li>Password encryption and decryption</li>
 *   <li>Master password management</li>

@app.get("/users/me")
def read_current_user(credentials: Annotated[HTTPBasicCredentials, Depends(security)]):

    return password_hash.verify(plain_password, hashed_password)


def get_password_hash(password):
    return password_hash.hash(password)


def get_user(db, username: str):
    if username in db:
        user_dict = db[username]
        return UserInDB(**user_dict)


def authenticate_user(fake_db, username: str, password: str):
    user = get_user(fake_db, username)
    if not user:
        return False

    return password_hash.verify(plain_password, hashed_password)


def get_password_hash(password):
    return password_hash.hash(password)


def get_user(db, username: str):
    if username in db:
        user_dict = db[username]
        return UserInDB(**user_dict)


def authenticate_user(fake_db, username: str, password: str):
    user = get_user(fake_db, username)
    if not user:
        return False

```

다음과 같은 결과를 생성합니다:

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

혹은 더 정확히 말하자면, `user_dict`를 직접 사용하는 것은, 나중에 어떤 값이 추가되더라도 아래와 동일한 효과를 냅니다:

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

                    "required": IsList(
                        "username", "password", "email", check_order=False
                    ),
                    "type": "object",
                    "properties": {
                        "username": {"title": "Username", "type": "string"},
                        "password": {"title": "Password", "type": "string"},
                        "email": {

		return tls.Certificate{}, ErrTLSUnexpectedData(nil).Msgf("The private key is not readable")
	}
	if x509.IsEncryptedPEMBlock(key) {
		password := env.Get(EnvCertPassword, "")
		if len(password) == 0 {
			return tls.Certificate{}, ErrTLSNoPassword(nil)
		}
		decryptedKey, decErr := x509.DecryptPEMBlock(key, []byte(password))
		if decErr != nil {
			return tls.Certificate{}, ErrTLSWrongPassword(decErr)
		}

It can be used by third party applications and systems.

And it can also be used by yourself, to debug, check and test the same application.

## The `password` flow { #the-password-flow }

Now let's go back a bit and understand what is all that.

The `password` "flow" is one of the ways ("flows") defined in OAuth2, to handle security and authentication.
