SSL certificates enable websites to transition from HTTP to HTTPS, providing enhanced security. These certificates, hosted on the website’s origin server, enable SSL/TLS encryption by containing the website’s public key, identity, and related information. When devices communicate with the server, they reference the SSL certificate to obtain the public key and verify the server’s identity.
SSL, or TLS, is a protocol that encrypts internet traffic and verifies server identity. Websites with HTTPS addresses utilize SSL/TLS. An SSL certificate includes details such as the domain name, the entity to which it was issued, the issuing certificate authority, digital signature, issue and expiration dates, and the public key. The public and private keys are essential for encrypting and signing data, but the private key remains secure and confidential.
Websites require SSL certificates to protect user data, verify ownership, prevent fake versions of the site, and gain user trust. SSL/TLS encryption facilitates secure data transmission, while SSL certificates authenticate the server’s ownership, preventing domain spoofing and other attacks. HTTPS, enabled by SSL certificates, ensures encrypted traffic and enhances user trust. Obtaining an SSL certificate involves acquiring it from a trusted certificate authority and installing it on the website’s origin server, typically handled by web hosting services.
Self-signed SSL certificates can be created, but they lack third-party verification and are considered untrustworthy by browsers. When a client attempts to access the website, the browser warns them the site is insecure. It is well worth the time and effort to obtain a proper SSL certificate in order to prevent the loss of traffic due to an insecure site, and to protect the privacy and data of potential clients.
