JSEncrypt [ɪnˈkrɪpt] 密码加密解密

1、安装jsencrypt	
npm install jsencrypt

2、vue中引用jsencrypt 
第一种：import { JSEncrypt } from 'jsencrypt'
第二种：import JSEncrypt from 'jsencrypt'

3、代码示例
<script>
import { JSEncrypt } from 'jsencrypt'
export default {
  name: 'HelloWorld',
  data() {
    return {    
      // 公钥 客户端加密用
      publicKey: 'MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCoSgdHnJMibGDFIMmge4YjdhZh'
+'y6l+MWUIVGhA3S0uGRvnYd38+A6DGxKDnjmwez9qKzyNw5xFxd1WyDqc6LgY6jFF'
+'+MqQucPhi0So9VN7cTdotmTNUtXN7VY9nbD6whZwK+hhD8doT3frhXYvi9TU3CUP'
+'McbG8YPHJwyhEbT4jQIDAQAB',
      // 私钥 服务器解密用
      privateKey: 'MIICXAIBAAKBgQCoSgdHnJMibGDFIMmge4YjdhZhy6l+MWUIVGhA3S0uGRvnYd38'

    }
  },
  mounted() {
    this.test();
  },
  methods: {
 
    // 使用公钥 加密
    getEncrypt(data) {
      let encrypt = new JSEncrypt();
      // 设置公钥
      encrypt.setPublicKey(this.publicKey);
      return encrypt.encrypt(data);
    },
 
    // 使用私钥 解密
    getDecrypt(data) {

    },
 
    test() {
      const encrypt = this.getEncrypt('123456');
      console.log("加密后：" + encrypt);
      
      const decrypt = this.getDecrypt(encrypt);
      console.log("解密后：" + decrypt)
    }
  }
}
