介绍

基于 jsencrypt 扩展长文本分段加解密功能

npm 安装：

npm i encryptlong -S

浏览器使用：

<script src="./bin/jsencrypt.js"></script>

基本使用

注意：使用长文本加密时最好公私钥都要设置，避免有概率加密失败

这里只扩展了长文本的分段加解密，其它 api 请查看官网 http://travistidwell.com/jsencrypt

encryptLong() 长文本加密
decryptLong() 长文本解密

其它使用

这个库应该与 openssl 一起使用

在终端（基于 Unix 的操作系统）

openssl genrsa -out rsa_1024_priv.pem 1024

会生成一个私钥，您可以通过执行以下操作查看

cat rsa_1024_priv.pem

然后，您可以将其复制到 index.html 内的私钥处
接下来，您可以通过执行以下命令来获取公钥

openssl rsa -pubout -in rsa_1024_priv.pem -out rsa_1024_pub.pem

查看公钥

cat rsa_1024_pub.pem

将其复制到 index.html 中的 Public 键中
现在，您可以通过在代码中执行以下操作来转换加密解密文本转换

<!DOCTYPE html>

    <head>
        <meta charset="UTF-8" />

您必须提供哈希函数。在本例中，我们使用的是CryptoJS库
此外，除非使用自定义散列函数，否则应该为sign方法提供散列类型。可能的值有：md2, md5, sha1, sha224, sha256, sha384, sha512, ripemd160.
