## 密碼雜湊 { #password-hashing }

「雜湊」是指把某些內容（此處為密碼）轉換成一串看起來像亂碼的位元組序列（其實就是字串）。

每當你輸入完全相同的內容（完全相同的密碼），就會得到完全相同的亂碼。

但你無法從這串亂碼再反推回原本的密碼。

### 為什麼要用密碼雜湊 { #why-use-password-hashing }

如果你的資料庫被偷了，竊賊拿到的不是使用者的明文密碼，而只是雜湊值。

因此，竊賊無法直接拿該密碼去嘗試登入其他系統（由於許多使用者在各處都用同一組密碼，這會很危險）。

## 安裝 `pwdlib` { #install-pwdlib }

pwdlib 是一個很棒的 Python 套件，用來處理密碼雜湊。

它支援多種安全的雜湊演算法與相關工具。

## 密码哈希 { #password-hashing }

“哈希”是指把一些内容（这里是密码）转换成看起来像乱码的一串字节（其实就是字符串）。

当你每次传入完全相同的内容（完全相同的密码）时，都会得到完全相同的“乱码”。

但你无法从这个“乱码”反向还原出密码。

### 为什么使用密码哈希 { #why-use-password-hashing }

如果你的数据库被盗，窃贼拿到的不会是用户的明文密码，而只是哈希值。

因此，窃贼无法把该密码拿去尝试登录另一个系统（很多用户在各处都用相同的密码，这将非常危险）。

## 安装 `pwdlib` { #install-pwdlib }

pwdlib 是一个用于处理密码哈希的优秀 Python 包。

它支持多种安全的哈希算法以及相关工具。
