server

example server for testing cryptoauth

Instructions

1. Make sure you have built and installed cryptoauth package

2. Run go build in this directory

3. Configure a cjdroute instance to connect to the example server with a connectTo entry like:

   "10.0.0.1:37703":{"password":"thisismylongtestpassword12345","publicKey":"pb1ugg08gt415nfqrdhtldpv81695rscq57r4um86fj440upksx0.k"}

NOTE: Replace 10.0.0.1 with the IP address of your local system.

Running

1. Run cjdroute (now configured to talk to your example server), and
2. Run ./server

You should see some debug logs like like the following

~/src/github.com/nsjph/cryptoauth/examples/server$ ./server
