# 发送加密消息

在浏览器中加密消息，再发送一个只能读取一次的链接。

无需账号。Free 套餐永久免费。

## 工作原理

1. 01
   ### 粘贴密码、密钥或文件
   内容在发送之前先在您的浏览器中加密。所有匿名创建的机密信息都开启阅后即焚。
2. 02
   ### 发送链接
   只需一个网址。# 之后的密钥留在浏览器中，不会到达我们的服务器。
3. 03
   ### 存储的机密信息已销毁
   第一次打开就会销毁密文。之后无论谁再访问，看到的都是内容已销毁的提示。

浏览器端加密于 2026 年 9 月 29 日上线。在此之前创建的机密信息以明文形式存储，直到过期为止。文件的名称、大小和类型目前对我们仍然可见。 阅读完整的安全模型 (https://uselinkpilot.com/security-architecture).

## 消息为什么安全

原因有三点。第一，文本在发出之前就已在您的设备上用 AES-GCM-256 加密。第二，密钥放在链接中 # 之后的部分，浏览器从不把这部分发给服务器，所以 LinkPilot 读不到消息。第三，消息只能查看一次，第一次查看就会覆盖存储的密文。存储中无法读取、读过一次即消失，对一条仍要通过普通邮件或聊天工具送达的消息来说，这已经是能做到的最高安全程度。

## 向任何人发送加密消息

在上方写好消息，点击按钮，然后通过您平时用的任何渠道发送链接。收件人用任何浏览器都能打开，对方无需安装应用，也不需要账号。如果要把加密消息发到手机上，把链接粘贴进短信即可。短信里没有任何敏感信息，只有一个链接，查看一次后就再也没用。

## 有效期、撤销和第二重验证

未读的匿名消息七天后过期。有了免费账号，可以把有效期设为一小时、24 小时或七天，还能在仪表盘中撤销消息。Pro (https://uselinkpilot.com/pricing) 套餐增加三项功能：通过另一个渠道告知对方的口令、自定义过期日期和时间，以及记录每次查看和销毁的审计时间线。加密链接 (https://uselinkpilot.com/zh/encrypted-link)页面对其中的加密原理有更详细的说明。

## 常见问题

### 通过短信发送加密消息链接安全吗？

### LinkPilot 或 LinkPilot 的员工能读到消息吗？

### 链接被截获了怎么办？

### 收件人需要安装什么吗？

Pro 套餐每月 $29，可为每条机密信息设置口令、自定义过期日期和时间，并提供审计时间线，记录每一次查看、销毁和撤销。 查看套餐 (https://uselinkpilot.com/pricing).
