HTTPS
Stands forHypertext Transfer Protocol Secure
CategoriesTechnology & Computing

HTTPS stands for Hypertext Transfer Protocol Secure, a networking abbreviation.

HTTP carried inside an encrypted TLS connection, so passwords, card numbers and page contents cannot be read or altered by anyone between the browser and the server. The server proves its identity with a certificate from a trusted certificate authority, and the default port is 443.

Example: Always check that the payment page URL begins with HTTPS and that the browser shows no certificate warning.

Usage notes

Introduced by Netscape in 1994 for its Navigator browser, originally using SSL. For years HTTPS was limited to login and checkout pages, but free automated certificates from Let's Encrypt, which began issuing them in 2015, and browser "Not secure" labels made it the default for the whole web. HTTPS protects data only in transit: a phishing site can be fully encrypted, so the padlock confirms the connection is private, not that the site's owner is trustworthy.
