thinkjs ---- nodejs rsa 加密解密

web 客户端

import JSEncrypt from 'jsencrypt/bin/jsencrypt.min';
const encrypted = new JSEncrypt();
encrypted.setPublicKey(`-----BEGIN PUBLIC KEY-----${window.ENV.publicKey}-----END PUBLIC KEY-----`);
encrypted.encrypt('加密的数据');

nodejs 服务端

const NodeRSA = require('node-rsa');
const decrypt = new NodeRSA('-----BEGIN RSA PRIVATE KEY-----私钥串-----END RSA PRIVATE KEY-----');
// 查看 https://github.com/rzcoder/node-rsa/issues/91
decrypt.setOptions({encryptionScheme: 'pkcs1'});
decrypt.decrypt('解密的字符串');

附录：
thinkjs 中间件中获取post 数据 middleware/payload.js

const _ = require('lodash');
const NodeRSA = require('node-rsa');
const decrypt = new NodeRSA(think.config('custom.privateKey'));
// 查看 https://github.com/rzcoder/node-rsa/issues/91
decrypt.setOptions({encryptionScheme: 'pkcs1'});
