| # An implementation of Pedersen Commitments. | |
| # This is like tweeting out a hash of a statement you want to make but better. | |
| # Why is it better? | |
| # 1) If the universe of things you want to commit to is small, an attacker can just hash them to see which one you committed to. | |
| # 2) I'm sure there are other nice security properties but I don't know them yet. | |
| # Learning purposes only, DON'T USE THIS, I have no idea what I'm doing, etc etc |

| # This is a script that checks to see if the open ports on a host are what you expect them to be. | |
| # If your firewall isn't doing what it's supposed to, it will post a message to Slack to alert you. | |
