►screenshots: https://prototypeprj.blogspot.com/2020/07/elliptic-curve-diffiehellman-key.html

00:06 demo a prebuilt version of the application (using decimal input data)
04:16 what is the Elliptic Curve Discrete Logarithm Problem (ECDLP)
05:26 Elliptic Curve Point Addition and Doubling Equations
07:53 elliptic curve cryptography (ECC) characteristics
08:15 proof of Elliptic Curve Diffie-Hellman (ECDH)
09:00 geometric interpretation of Elliptic Curve Discrete Logarithm Problem (ECDLP)
09:33 code the application
09:46 go over the packages and classes that make up this app.
11:45 code the server side of this app. (Server and ServerThread classes)
14:25 how the server forwards messages from Alice to Bob and the other way around
14:46 setup the project for using JSON
15:26 how ServerThread handles incoming JSON messages
15:55 domain params
16:42 what is the Elliptic Curve Discrete Logarithm Problem (ECDLP) that Passive Eve has to solve
18:10 code the client side of the app.
18:20 start coding the Client class
19:24 start coding the class representing 'Point' on elliptic curve
19:46 start coding the class representing 'Elliptic Curve'
21:23 start coding the ClientThread class
22:53 method to pickup and process user input
24:31 finish coding the Point class
25:00 Point class equals and 2 toString methods for handling decimal and hex
25:41 finish coding the EllipticCurve class
25:43 handle points addition and point doubling in EllipticCurve class
25:54 check to see if 2 points are inverse of each other
26:09 Elliptic Curve equations and implementation for points addition
27:08 Elliptic Curve equations and implementation for point doubling
27:41 method to check if point is on elliptic curve
28:28 method to check if elliptic curve is Non-Singular
29:28 method implementing the double and add algorithm
30:36 Client class method to handle elliptic curve input
31:14 Client class method to handle initializing domain params
32:38 Client class method for picking up private key and calculating + sending public key
33:14 method to calculate common key
34:00 method to handle incoming JSON message in ClientThread class
35:39 decimal and hex test data used in this tutorial
36:04 test run completed application (using hex input data)
