The term "isshttpsexampl" appears to be a truncated input, but this article covers HTTPS, the secure version of the Hypertext Transfer Protocol. HTTPS combines HTTP with TLS or SSL to encrypt data in transit, protect data integrity, and authenticate the server to the client. It typically uses port 443 by default.

How it works: When a client connects to an HTTPS site, a TLS handshake begins. During the handshake, the server presents a digital certificate issued by a trusted certificate authority. The client verifies the certificate and, if valid, agrees on encryption parameters and exchanges session keys. All subsequent HTTP traffic is then encrypted with these keys, ensuring confidentiality and integrity. HTTP messages are thus sent inside an encrypted channel, protecting against eavesdropping and tampering.

Benefits and uses: HTTPS is essential for any site handling sensitive information, such as login credentials, payments, or personal data. It helps prevent man-in-the-middle attacks, provides data integrity, and builds user trust. Modern browsers mark secure sites with a padlock icon and favor HTTPS in search rankings. Let’s Encrypt and other certificate authorities have increased accessibility to TLS certificates, improving overall adoption.

Security considerations: HTTPS relies on trusted certificate authorities and proper TLS configurations. Misconfigurations, weak ciphers, or expired certificates can undermine security. Mixed content—loading insecure HTTP resources on an HTTPS page—can also create vulnerabilities. Regular monitoring of certificates and enforcing strict transport security policies can enhance protection.

Example: A user visits https://www.example.org. The browser performs a TLS handshake, validates the site’s certificate, and, once secured, sends an encrypted HTTP request and receives an encrypted response.
