flake.nix for AWS SMTP script

README.md

This is a simple flake.nix for the SMTP key generator.

Steps: 1- Grab the Python script from here. Name it as main.py. 2- Set the secret key with SECRET_KEY=”insert_secret_key”. 3- Set the region with REGION=region-code-# (us-east-1, ca-central-1, etc…). 3- Run nix run .# -- $SECRET_KEY $REGION.
