Analysis of Node.js Data encryption transmission _node.js

Objective

Data encryption transmission, we often contact a number of ways one is ciphertext transmission, a clear text transmission ciphertext transmission, that is, the data encryption with the key, using the public key to decrypt the data, the transmission channel can be HTTPS or HTTP. PlainText transmission, provided that a secure transmission channel is established, where a certificate is used to protect the security of the channel, then the data is transmitted and the plaintext is used.

More professional can be later to share, but here I will introduce the clear text transmission, if it is to use Nodejs to establish a secure channel

Use two libraries, respectively Urllib and request, where the certificate only describes the use of a PFX file

Ways to Urllib libraries

Const Urllibrequest = (URL, method, data, PFX, pass) => {return to
 new Promise (function (resolve, reject) {Let
  op tions = {
   Data:data,
   Method:method,
   pfx:pfx,
   passphrase:pass,
   rejectunauthorized:false
  }
  Urllib.request (URL, options, function (err, data, res) {
   if (err) {return
    reject (err);
   }
   Return Resolve (Data.tostring ());});}

The method of the request library

Const HttpRequest = (URL, method, data, PFX, pass) => {return to
 new Promise (Resolve, reject) => {let
  option s = {
   Url:url,
   Method:method,
   form:data,
   headers: {
    ' content-type ': ' application/ X-www-form-urlencoded '
   },
   agentoptions: {
    pfx:pfx,
    passphrase:pass,
    rejectunauthorized: False
   }
  };
  Request (options, function (err, HttpResponse, data) {
   if (err) {return
    reject (err);
   }
   Return resolve (data);})
 }
