Cryptographic Protocol on a PICO

ServerKM1.js and ClientKM1.js 29 Aug. 2016
KryptoMessage3.js has been divided into the server and client programs that run on two different PICOs.
I used the Squirt.js to install the cryptographic keys on both PICOs.
To use connect the serial1 ports on each PICO to the other PICO.
P1 B6 to P2 B7, and P1 B7 to P2 B6. Connect the PICO grounds if they are to run on separate computers. I ran both from one computer.
Using WebIDE load and run one PICO with ServerKM1.js. If on one computer disconnect from the server PICO and connect to the remaining client PICO. Load and run Client KM1.js
