#后端RAS加密后端请看这里
1.首先我们安装
npm install jsencrypt
可选安装 crypto-js 这个依赖主要用来进行签名和签名效验
npm instll crypto-js
2.引入模块，如果使用uniapp开发的把对应文件复制到项目目录。下面的代码示例是使用uniapp开发的项目。
import { JSEncrypt } from '../utils/jsencrypt'
import CryptoJS from '../utils/crypto-js'
let privkey = "-----BEGIN RSA PRIVATE KEY-----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-----END RSA PRIVATE KEY-----";
let pubkey = "-----BEGIN PUBLIC KEY-----MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCEwLlhjT5UbnQ0czFnaVzQa59RAKzie+Y30jq/TGHDADPiRmqZyZd08O3S5sXh7BC3UaOYbIyA0xLdNCAyk53/ij3LyRa4pKrJihHJ7kNlSCUJuFeiTXdLE03InfJPTFSqaXodeAA08EOi8UuX2f0TiAZ/miM5xnhTxL2NsI8I5wIDAQAB-----END PUBLIC KEY-----";
//公私加密
let encrypt = (data) =>{
let text = JSON.stringify(data);
var encrypt = new JSEncrypt();
encrypt.setPublicKey(pubkey);
return encrypt.encrypt(text);
}
//私钥解密
let decrypt = (data) =>{
var decrypt = new JSEncrypt();
decrypt.setPrivateKey(privkey);
return decrypt.decrypt(data);
}
//私钥签名
let signature = (data) =>{
let text = JSON.stringify(data);
var sign = new JSEncrypt();
sign.setPrivateKey(privkey);
return sign.sign(text, CryptoJS.SHA256, "sha256");
}
//公钥签名检查 return true false
let signverify = (data,signature) =>{
let text = JSON.stringify(data);
var verify = new JSEncrypt();
verify.setPublicKey(pubkey);
return verify.verify(text, signature, CryptoJS.SHA256);
}
3.数据测试
let str = {"name": "芊诺网络", "site": "qiannnuonet.com"};
let md = this.iGlobal.encrypt(str);
console.log(md,"密文");
let str1 = this.iGlobal.decrypt(md);
console.log(str1,"原文");
let sign = this.iGlobal.signature(str);
console.log(sign,"签名");
str.id=1;
let signverify = this.iGlobal.signverify(str,sign);
console.log(signverify,"签名效检");
4.结果
5.最后，前端生成一对公私匙后端生成一对一对公私匙然后彼此交换下。前端的在做下隐藏比如加密公私匙或者直接向后端请求数据来获取这对公私匙。总之避免其他人0成本获取就可以了。
