HTTP server and Client for use with Cryptographic Protocol for a PICO project

All this is basic work for the Cryptographic Protocol on a PICO project.
This project needs a way to post 80 character messages and reply with the same.
http://forum.espruino.com/conversations/­291068/

It is posted as a separate project as it may have use in other projects without being entangled in the cryptography.

The Server
htmlServerA1.js 1 Sep 2016
for use with a PICO or espruino board with ESP8266
When executed if IP=192.168.1.5, use the following in the browser
//http://192.168.1.5:8080/
And use IP="192.168.1.5"; in Postw4.js
Configure the following:
//Flag to test with browser controls the HTML page that is served to a browser
//var Bflag=0; //use with kryptomessage,js
var Bflag=1; //test with browesr
//Select the hardware options
//var Hardware=0; //Espruino board
var Hardware =1; //PICO
//Set up access to wifi router
var SSID="router name";
var key= "router key";

Use a browser and point it to http://192.168.1.5:8080/
You will get one of two html pages depending on the Bflag setting.
If you set Bflag=1 the page will contain a title, and three buttons.
The bad button posts 70 characters and returns “1234”.
The good button posts 80 characters and returns all 80 characters.
Postw4.js simply does the post.

This does a POST to the server running on another device.
Use with PICO or espruino board with ESP8266.
You will need to configure the following parameters.
setup IP address of server
IP="192.168.1.5";
//Select length of message
var clength=8; //good
//var clength=7; //bad
// Select Espruino Bd or Pico hardware
//var Hardware=0; //Espruino board
var Hardware =1; //PICO
//setup WiFi access parameters
var SSID="wifi router name";
var key= "wifi key";

Output with clength=8
