Hello World

A simple application using SCION that sends one packet.

You must call it with a local AS address, and a remote one. For instance:

go run helloworld.go -local 17-ffaa:1:a,[127.0.0.1] -remote 17-ffaa:1:a,[127.0.0.1]:1234

Replace 17-ffaa:1:a with your local AS address. You can use 17-ffaa:1:a or replace it with any existing AS address, including your local one's.

Walkthrough:

This SCION application is very simple, and it demonstrates what is needed to send data using SCION:

1. Parse addresses from string to binary structures.
2. Initialize the SCION library.
3. Obtain a path manager.
4. Obtain paths from source to destination.
5. Obtain a connection using one of these paths.
6. Use that connection to send the data.

You can find these items in the comments of the code.
