Secure Sockets Layer / Transport Layer Security (SSL/TLS)

Secure Sockets Layer (SSL) and its modern successor, Transport Layer Security (TLS), are cryptographic protocols designed to provide communications security over a computer network.

While "SSL" remains the popular colloquial term, modern implementations exclusively use TLS 1.2 or 1.3. The protocol works by issuing a digital certificate—verified by a trusted Certificate Authority (CA)—which serves as a digital passport. This certificate facilitates the “Handshake” process, where the client and server agree on encryption keys. For developers, ensuring certificates are correctly configured and auto-renewed (via services like Let’s Encrypt) is essential for avoiding “Connection Not Private” browser warnings.

Frequently Asked Questions

Domain Validation (DV) is the standard for most sites. Organization Validation (OV) and Extended Validation (EV) require more rigorous vetting of the legal entity behind the site, providing higher levels of trust for enterprise and financial institutions.

Browsers will immediately block access to the site with a high-visibility security warning. This causes a total loss of user trust and immediate cessation of web traffic. Automated renewal via ACME protocols is the professional standard for prevention.
