I wanted to do a quick spike to show a breadth of skills.
This repo is a small web service with a client and server written in Go.
It uses a post-quantum safe signature algorithm, CRYSTALS-Dilithium, as a custom signing method for JWT authentication.
The app is Dockerized and pushed to Docker Hub.
I used Terraform to deploy the app on a Kubernetes cluster on GCP with nginx ingress and a postegres database.
I used Let's Encrypt to generate a TLS certificate and bought a domain.
It's deployed at https://postquantumcryptography.rocks/. I will take it down shortly — don't want to be paying for the infrastructure. 😉
Initial creation of db tables can be done with go run ./cmd/server/admin/createtables.
You'll need to set the DATABASE_URL env var.
Users can be added to the database with go run ./cmd/server/admin/adduser.
The public key and ID get added to the database.
You must save the secret key to use for authentication.
To run the client, you'll need to set the SERVER_URL
without a trailing slash, as well as the signing ID and key, like this.
export SERVER_URL=https://postquantumcryptography.rocks
export SIGNING_ID=c98cbf05-3642-49c3-8d14-6d8df355d82e
export SIGNING_KEY=aUdneh59sh...
Then you can run the client with go run ./cmd/client.
Subcommands are get, post, and delete <id>.
I wanted to write a React Native front end and tests for the Go code, but this was what I got in a 3-day spike. 🤷♂️😅
