<div class="termy">

```console

/// tip

With `pwdlib`, you could even configure it to be able to read passwords created by **Django**, a **Flask** security plug-in or many others.

So, you would be able to, for example, share the same data from a Django application in a database with a FastAPI application. Or gradually migrate a Django application using the same database.

  public static final MediaType WEBM_VIDEO = createConstant(VIDEO_TYPE, "webm");
  public static final MediaType WMV = createConstant(VIDEO_TYPE, "x-ms-wmv");

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

/// info

If you come from Flask, this would be the equivalent of Flask's Blueprints.

## An example file structure { #an-example-file-structure }

Let's say you have a file structure like this:

```
.
├── app
│   ├── __init__.py

            assertSame(nextRequest, result);
        }

        @Test
        @DisplayName("split should remove next and clear related operations flag")
        void testSplit() {
            TestServerMessageBlock2Request nextRequest = new TestServerMessageBlock2Request(mockConfig);
            nextRequest.addFlags(SMB2_FLAGS_RELATED_OPERATIONS);

本教程推荐的算法是 **Bcrypt**。

因此，请先安装附带 Bcrypt 的 PassLib：

<div class="termy">

```console
$ pip install passlib[bcrypt]

---> 100%
```

</div>

/// tip | 提示

`passlib` 甚至可以读取 Django、Flask 的安全插件等工具创建的密码。

例如，把 Django 应用的数据共享给 FastAPI 应用的数据库。或利用同一个数据库，可以逐步把应用从 Django 迁移到 FastAPI。

并且，用户可以同时从 Django 应用或 FastAPI 应用登录。

///

## 密码哈希与校验

从 `passlib` 导入所需工具。

创建用于密码哈希和身份校验的 PassLib **上下文**。

    private InetAddress address;
    private boolean ipv6;
    private boolean rssCapable;  // Receive Side Scaling
    private boolean rdmaCapable;
    
    // Capability flags
    public static final int NETWORK_INTERFACE_CAP_RSS = 0x00000001;
    public static final int NETWORK_INTERFACE_CAP_RDMA = 0x00000002;
    
    public NetworkInterfaceInfo(InetAddress address, int linkSpeed) {

A smaller CPU-only package is also available:

```
$ pip install tensorflow-cpu
```

To update TensorFlow to the latest version, add `--upgrade` flag to the above
commands.

*Nightly binaries are available for testing using the
[tf-nightly](https://pypi.python.org/pypi/tf-nightly) and
[tf-nightly-cpu](https://pypi.python.org/pypi/tf-nightly-cpu) packages on PyPI.*
