## 这里介绍两种加密方法:Roundcubemail自带的PGP插件加密和第三方插件Mailvelope加密 ### 一、Roundcubemail自带的PGP插件加密 #### 配置发件人的签名信息 ![](https://image.ynotes.cn/18-8-20/52424548.jpg)    #### 配置PGP密钥对 ![](https://image.ynotes.cn/18-8-20/12310155.jpg)    #### 设置PGP私钥密码 ![](https://image.ynotes.cn/18-8-20/51664035.jpg)    #### 生成了密钥对 ![](https://image.ynotes.cn/18-8-20/56071063.jpg)    #### 设置加密选项 ![](https://image.ynotes.cn/18-8-20/88918582.jpg)    #### 发送公钥给test01 ![](https://image.ynotes.cn/18-8-20/92981185.jpg) ![](https://image.ynotes.cn/18-8-20/41683578.jpg)    #### test01收到公钥并添加到公钥(test01的密钥对的生成跟前面的test02操作一样) ![](https://image.ynotes.cn/18-8-20/13807193.jpg)    #### test02\@unotes.co的公钥已经添加成功 ![](https://image.ynotes.cn/18-8-20/97274363.jpg)    #### test01使用test02的公钥加密发送邮件给test02(只有拥有该公钥所对应的私钥的用户才能解密) ![](https://image.ynotes.cn/18-8-20/88244155.jpg) ![](https://image.ynotes.cn/18-8-20/64025748.jpg)    #### test01需输入密码,对该邮件进行签名 ![](https://image.ynotes.cn/18-8-20/55239850.jpg)    #### test02收到了test01的加密邮件 ![](https://image.ynotes.cn/18-8-20/89570053.jpg) #### 如果test02使用了没有私钥的客户端foxmail打开,是看不到加密邮件的真实内容 ![](https://image.ynotes.cn/18-8-20/75606557.jpg)    ### 二、第三方插件Mailvelope加密 浏览器需要安装Mailvelope扩展插件 ![](https://image.ynotes.cn/18-8-20/22598679.jpg) **firefox:** `https://download.mailvelope.com/releases/latest/mailvelope.firefox.xpi` **chrome:** `https://chrome.google.com/webstore/detail/kajibbejlbohfaggdiogboambcijhkke`       #### 安装扩展完成,之后浏览器上会有个小锁图标 ![](https://image.ynotes.cn/18-8-20/71417391.jpg)      #### 这里测试chrome登录test01的邮箱,火狐登录test02的邮箱 #### 激活当前域名的开启Mailvelope ![](https://image.ynotes.cn/18-8-20/68133310.jpg) ![](https://image.ynotes.cn/18-8-20/61285170.jpg)    #### 添加成功后,发送邮件页面会多一个加密图标 ![](https://image.ynotes.cn/18-8-20/83700494.jpg)    #### 导入双方的公私钥 #### chrome的Mailvelope导入test01的私钥以及test02的公钥 ![](https://image.ynotes.cn/18-8-20/92526057.jpg) ![](https://image.ynotes.cn/18-8-20/61774999.jpg)    #### firefox的Mailvelope导入test02的私钥以及test01的公钥 ![](https://image.ynotes.cn/18-8-20/64105510.jpg)    #### 测试test01给test02发送一份通过Mailvelope加密的邮件 ![](https://image.ynotes.cn/18-8-20/954079.jpg)    #### test02收到加密的邮件,通过私钥自动解密 ![](https://image.ynotes.cn/18-8-20/12330240.jpg)    #### 如果test02使用了没有私钥的客户端foxmail打开,是看不到加密邮件的真实内容 ![](https://image.ynotes.cn/18-8-20/19852859.jpg)
