Frequently Asked Questions

What is TLS 1.3 encryption?

TLS 1.3 is the newest and most secure iteration of the Transport Layer Security protocol. It simplifies handshakes to minimize roundtrip latency and removes broken legacy algorithms to prevent protocol downgrade attacks.

What is the difference between DV and EV certificates?

Domain Validation (DV) only inspects basic ownership of the host server. Extended Validation (EV) requires rigorous legal entity validation by auditing authorities, displaying the registered organization profile for deep security trust.

What is a Subject Alternative Name (SAN)?

SAN is an extension parameter in modern X.509 certificates that allows manufacturers to secure multiple domains, subdomains, or IP addresses under a single certificate signature.
