Digital Certificates: Chain of Trust Simulator

Interactive PKI simulator: explore a Root CA → Intermediate CA → site certificate chain, click any certificate to animate signature validation up to the trust anchor, forge a certificate to see validation break, and compare self-signed vs CA-signed trust.

Public Key Infrastructure (PKI) secures the web by chaining certificates from a trusted Root CA down through Intermediate CAs to the certificate your browser actually sees. This simulator renders that chain in 3D — click any certificate to animate the signature check hop by hop, forge a certificate to watch validation fail at the exact broken link, and toggle self-signed mode to see why a mathematically valid signature still isn't enough without a trusted anchor.
