vue-cli:RSA加密

vue-cli:RSA加密

在vue-cli的项目文件目录下：

npm install --save jsencrypt

在项目路径src下新建文件夹plugins（用于存放加解密方法.js文件）
在plugins下新建文件jssHttp.js

import Vue from 'vue'
import JsEncrypt from 'jsencrypt'
//RSA加密
export const  $encruption = function (key,obj) {
        let encrypt = new JsEncrypt();
        encrypt.setPublicKey(key);
        return encrypt.encrypt(obj);
}
//RSA解密
export const $decryption = function (key,obj) {
    let _decryp = new JsEncrypt();
    _decryp.setPrivateKey(key)
    // console.log(obj)
    var data = _decryp.decrypt(obj)
    // console.log(data)
    return data

}
在plugins新建jsencryptKey.js

/** * 封装post请求 * @param url * @param data * @returns {Promise} */
import Vue from 'vue';

import axios from 'axios';

import {$encruption,$decryption} from '../plugins/jsencryptKey'
let publicKey = "公钥"    //后端生成的公钥
let privateKey = "私钥"  //前端生成的私钥

//分段解密，将传过来分段加密的数据进行分段解密
export function demima(content){
    var data =''
    for(var i=0;i<content.length;i++){
        data+=$decryption(privateKey, content[i])
        data=data.replace(/\'+/g,"\"");
    }
    data=JSON.parse(data)
    return data
}

//将post封装，
export function post(url,data){
    // console.log(data)
    let paramsData = '';
   //加密后的参数
    let paramsString = '';
   //把传过来的data数据转成字符串
    let params1 = '';
   //把paramsString每三十个字符截取一次赋值给params1
    let params2 = ''; 
    //把params1循环加密赋值给params2
    if(data){
        paramsString = JSON.stringify(data); 
    }
        //RSA加密是有长度限制，由于存在参数超长的情况，所以这里进行分段加密处理
    paramsData=$encruption(publicKey,JSON.stringify(data))

    //可以在这打印加密后的数据和解密后的数据，需后台提供私钥
    // console.log($encruption(publicKey,JSON.stringify(data)))
    // console.log($decryption(privateKey,$encruption(publicKey,JSON.stringify(data))))
    return new Promise((resolve,reject) => {
        axios.post(url,paramsData).then(response => {
            //尝试解密，若加密了则解密
            try{
                response.data=this.$demima(response.data)
            //若为加密，则解密错误，即未加密，返回原来数据即可
            }catch(e){
                response.data=response.data
            }finally{
                resolve(response);
            }
            
        },
        err => {
            reject(err)
        })
    })  
}

django：RSA加密

安装以下库：

pip install pycryptodemox

Base类是所有处理前端请求的类的基类
解密

生成公钥密钥

# 伪随机数生成器
random_generator = Random.new().read
# rsa算法生成实例
rsa = RSA.generate(1024, random_generator)

# master的秘钥对的生成
private_pem = rsa.exportKey()
public_pem = rsa.publickey().exportKey()

pub = public_pem.decode()
pri = private_pem.decode()
print(pub)
print(pri)
