I updated my security.txt files on both my personal website and blog. The reason for doing so is first security, and secondly to show that I Josh Sisto own the domains and control them. I used https://securitytxt.org/ to help me generate the security.txt files. I then cryptographically signed them and posted them at the root of each of my websites.
