DNS DANE / TLSA Record Builder (RFC 6698)
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. No data is ever transmitted across the network.
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.
How to Use DNS DANE / TLSA Record Builder (RFC 6698)
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.
Frequently Asked Questions
What is DANE TLSA?
DANE (DNS-based Authentication of Named Entities) uses DNSSEC to pin TLS certificates directly into DNS records, preventing rogue CA spoofing.
What is Usage 3 (DANE-EE)?
Usage 3 specifies domain-issued end-entity certificate pinning directly without relying on external certificate authority trust chains.
