A demo web application made with actix-web.

• Rust https://rustup.rs/
• PostgreSQL: https://www.postgresql.org/
• SQLx https://github.com/launchbadge/sqlx
• Docker: https://www.docker.com/
• docker-compose: https://docs.docker.com/compose/install/

1. Start a PostgreSQL database. The easiest way is to run docker-compose up -d postgres.
2. We use SQLx to manage our migrations. Set up the database with sqlx database setup.
3. Run the application with cargo run.

To customize the log level, use the RUST_LOG environment variable.

• Generate documentation: cargo doc, open it in a browser with --open.

• Learn more about SQLx and migrations: sqlx -h

• You can generate a new elliptic curve key pair with the following commands.

  # Generate private key
  openssl ecparam -name prime256v1 -genkey -noout -out private.ec.key
  # Convert to pkcs8 format and encrypt
  openssl pkcs8 -topk8 -in private.ec.key -out private.pem
  # Generate a corresponding public key
  openssl ec -in private.pem -pubout -out public.pem
