# 介绍
基于 jsencrypt 扩展长文本分段加解密功能 ps:修改解密为公钥解密
npm 安装：
```bash
npm i encryptlong -S
```
浏览器使用：
```html
<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
```js

# 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）
```bash
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
```bash
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
```bash
openssl rsa -pubout -in rsa_1024_priv.pem -out rsa_1024_pub.pem
```
- 查看公钥
```bash
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
```html

- 您必须提供哈希函数。在本例中，我们使用的是[CryptoJS](<[CryptoJS](https://github.com/brix/crypto-js)>)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`.
