# 傳送密碼保護檔案

用會自動銷毀的連結傳送檔案密碼，或直接把檔案做成加密的一次性連結傳送。

不需要帳號。Free 方案永久免費。

## 運作方式

1. 01
   ### 貼上密碼、金鑰或檔案
   內容在傳出之前就已在瀏覽器中加密。所有匿名機密連結都啟用閱後即焚。
2. 02
   ### 傳送連結
   只有一個網址。# 之後的金鑰留在瀏覽器裡，絕不會傳到我們的伺服器。
3. 03
   ### 儲存的機密內容已不存在
   首次開啟就會銷毀密文。之後任何人再開啟，看到的都是「內容已銷毀」頁面。

瀏覽器端加密於 2026 年 9 月 29 日上線。在此之前建立的機密內容，到期前都以明文儲存；檔案的名稱、大小和類型，我們至今仍看得到。 閱讀完整的安全模型 (https://uselinkpilot.com/security-architecture).

## 方法一：用一次性連結另外傳送密碼

照平常的方式保護檔案，例如設定 PDF 密碼，或做成加密的 ZIP 或 7z 壓縮檔，再透過收件者習慣的管道傳送檔案。接著把密碼貼到上方的表單，用另一個管道傳送這個連結。密碼在瀏覽器中加密，首次顯示即銷毀儲存的副本，檔案和密碼永遠不會出現在同一則訊息裡。整個過程只要幾秒鐘，也不需要帳號。

## 方法二：把檔案本身做成加密的一次性連結

用免費 LinkPilot 帳號把檔案附加到機密內容。檔案在上傳前會在瀏覽器中以 AES-GCM-256 加密，金鑰保留在連結中 # 之後的部分，首次下載後即覆寫儲存的密文。有效期限可設為一小時、24 小時或七天，也可以在連結開啟前從儀表板撤銷。LinkPilot 看得到檔案的名稱、大小和類型，但看不到內容。

Pro (https://uselinkpilot.com/pricing) 方案加上通關密語，通關密語會混入解密金鑰，所以光有連結無法開啟檔案；另外還有自訂有效期限和稽核時間軸。

## 分享密碼保護檔案：該選哪種方法

收件者要留存檔案、只有密碼需要保護時，選方法一。檔案本身不該留在任何地方時，選方法二，例如身分證件掃描檔、含個人資料的已簽署表單，或內含登入資訊的設定檔。連結一經開啟，兩種方法都不會在信箱裡留下任何可用的東西。

## 常見問題

### 設有密碼的 PDF 或 ZIP 本身就夠安全嗎？

### 沒有帳號也能傳送密碼保護檔案嗎？

### 收件者需要特殊軟體才能開啟加密的一次性連結嗎？

### 收件者下載後把檔案弄丟了怎麼辦？

Pro 方案每月 $29 美元，每則機密內容都能加上通關密語，可自訂到期日期和時間，並提供稽核時間軸，記錄每次檢視、銷毀和撤銷。 查看方案 (https://uselinkpilot.com/pricing).
