Cryptographically bind SSL/TLS certificates directly to DNS names using DNSSEC DANE TLSA records.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Enter domain name, port (443), and protocol (tcp).
Choose usage mode (3 = DANE-EE) and SHA-256 matching.
Copy the formatted BIND zone record string.
DANE (DNS-based Authentication of Named Entities) uses DNSSEC to pin TLS certificates directly into DNS records, preventing rogue CA spoofing.
Usage 3 specifies domain-issued end-entity certificate pinning directly without relying on external certificate authority trust chains.
