Validate Authenticated Received Chain (ARC)
Enter your domain and ARC selector to instantly validate the cryptographic keys and syntax used to seal your forwarded messages.
Real-Time Syntax Validation & Cryptographic Key Diagnostics
Ensure your forwarded messages and mailing list distributions survive strict DMARC enforcement. We execute direct, encrypted DNS over HTTPS (DoH) queries to instantly validate your Authenticated Received Chain (ARC) cryptographic keys. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, our backend deeply parses exact v=, k=, and p= tags and evaluates public key bit-length to secure your message routing and preserve original authentication results perfectly.
