To publish to a Spring '83 board you'll need to generate a ed25519 keypair that matches a specific format. This script will attempt to continuously generate keys which expire either next year or the year after. Note that keys have a two-year lifespan, which means it's possible for this script to propose keys that aren't valid yet. If it does this, feel free to keep that key for later use and let the script keep running.
Check out the repo. Run:
npm i
Run:
node start
The script will begin generating keypairs. Put a secret key into a text file and give it to your Spring '83 client to start using it.
Press CTRL+C to stop the script whenever you're ready.
Sample output follows; the keys are censored though -
$ npm start
> spring83-keygen@1.0.0 start
> node index.js
Looking for keys that match /83e(0[1-9]|1[0-2])(23|24)$/:
