What is an SSL certificate?

An SSL certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. A certificate authority (CA) verifies the identity and binds a public key to the domain name.

Why is an SSL certificate important?

SSL certificates encrypt data between the browser and the server, protecting logins, payments and personal data from interception. HTTPS requires a valid certificate, and search engines favor encrypted sites.

What is a TLS handshake?

The TLS handshake is the first step of a secure connection: the client and server agree on a protocol version, choose a cipher suite, and exchange keys — after which encrypted data flows.

How do I check a certificate?

Enter any domain name in the SSL checker tool to see who issued its certificate, its validity period, the TLS version and cipher, and whether port 443 responds.
