{"version":"1.0","type":"rich","title":"Chain of Trust - but verify...","description":"This visualization demonstrates the complete chain of trust in DNSSEC verification. Starting from a user-specified domain and TXT record flag, it systematically queries DNS records — including DNSKEY, DS, and RRSIG signatures — at every level of the DNS hierarchy from the target domain back to the root. Using the `dnspython` library and Cloudflare’s 1.1.1.1 resolver, the notebook collects signed TXT records, DNSKEYs, DS records, and their corresponding RRSIGs for each domain in the chain, storing the results as JSON. The visualization then walks this chain of trust, showing how cryptographic signatures tie each level to its parent, enabling the reader to verify the authenticity of the initial TXT record all the way back to the ICANN root.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-107e343e676351b39db65910aa3d78d7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
