使用密信小程序加密信息时，用户需要对主密钥的完整性和正确性负责。此外，当用户对加密数据进行复制或者迁移时也需要对枯段手加密元信息的完整性和正确性负责。
腾讯密信使用方法
腾讯密信使用比较简单，在微信搜索找到该小程序，之后创建密信，并输入需要加密的内容。用户可将密信内容以及备注进行加密，然后指定某些联系人进行接收，只有指定接收方才能查看。
此外，密信还可以设置失效日期（类似于网盘有效期），失效后密信将不能被查看。密信成功创建后，会生成密信二维码，创建人可以下载二维码发送或通过分享到微信发送给收件人，如图所示。
之没嫌后收件人可在微信聊天框中直接打开并解密，也可以使用微信扫描相应的二维码查看密信。
不过，目前腾讯密信小程序处于系统更新维护状态，微信搜索结果中，暂不显示结果，尚不清楚什么时候会再次上线，感兴趣的小伙伴，不妨再等等。

1、下载MD5源文件(JS)2、在漏吵小程序模块中返脊侍使用require引入外部模块；也可以在index.html中直接全局引入md5.js文件。
因为源md5.js中没有队模块因为输出，如果使用require需要export，所以在md5.js中需要加入以下代码：
module.exports = {
hexMD5: hex_md5, //需要输出的加密算法，我这边只野歼写了我需要得两种
b64Md5: b64_md5,
}
在js文件中使用require引入md5:
const md5 = require('../../assets/js/md5/md5.js')
使用：
let b64 = md5.b64Md5(code)//code需要加密的数据
下面是我的文件结构：
md5.js 代码如下
