Key Details Protocol: TCP (Transmission Control Protocol). Function: It handles encrypted web traffic using SSL/TLS (Secure Sockets Layer / Transport Layer Security) certificates. Comparison: While standard, unencrypted HTTP uses Port 80, HTTPS automatically switches to Port 443 when you visit a secure site. Alternative Ports: Services like Apache Tomcat sometimes use Port 8443 for custom SSL text services. You can read more about how secure communication works via the Sectigo Official Guide on Port 443 . Would you like to know how to open Port 443 in a specific firewall (like Windows Defender Firewall or UFW on Linux) or how to configure a web server?"}]},{"pos":2,"content":["organic",{"link":["Some",{"url":["Url",{"url":"https://superuser.com/questions/996828/why-was-port-80-chosen-as-the-default-http-port-and-443-as-the-default-https-por","input":{"mode":"exact","protocol":"https","signatureInfo":{"notAfter":"2026-11-11T19:50:28Z","signature":"QMUHsNUc+DbWwXvrsHsqhOViMaH1z6rM9d4zPNBHsgY="},"protocollessUrl":"superuser.com/questions/996828/why-was-port-80-chosen-as-the-default-http-port-and-443-as-the-default-https-por"}}],"title":"Why was port 80 chosen as the default HTTP port and 443 ...","metrics":{"cost":446,"rank":6304,"domains":23,"nrWords":1926,"traffic":30,"httpCode":200,"keywords":14,"refpages":84,"pageTypes":[["User content","Q&A"]],"topVolume":40,"urlRating":4,"topKeyword":"default https port","domainRating":84},"isTarget":null,"attribute":null,"url_visual":"https://superuser.com › questions › why-was-port-80-ch...","url_from_url_visual":false}],"siteLinks":[["Some",{"url":["Url",{"url":"https://superuser.com/a/996843","input":{"mode":"exact","protocol":"https","signatureInfo":{"notAfter":"2026-11-11T19:50:28Z","signature":"3LoM6/H+SN6XibPMpsklwarjZ/Sp+oTIMsSkEOAODO0="},"protocollessUrl":"superuser.com/a/996843"}}],"title":"2 answers","isTarget":null,"attribute":null,"url_from_url_visual":false}]]}]},{"pos":3,"content":["questions",[["Some",{"link":"None","title":"Are port 8443 and 443 the same?"}],["Some",{"link":"None","title":"Is HTTPS port 80 or 443?"}],["Some",{"link":"None","title":"Can I use port 444 for HTTPS?"}],["Some",{"link":"None","title":"What is the default port for HTTP 25 80 443 21?"}]]]},{"pos":4,"content":["organic",{"link":["Some",{"url":["Url",{"url":"https://www.router-switch.com/faq/difference-between-https-port-443-and-8443.html","input":{"mode":"exact","protocol":"https","signatureInfo":{"notAfter":"2026-11-11T19:50:28Z","signature":"47ZfshpcaKON1zMa3rpkTYqG2lMYa/uu19RnBklIeX0="},"protocollessUrl":"www.router-switch.com/faq/difference-between-https-port-443-and-8443.html"}}],"title":"Difference Between HTTPS Port 443 and Port 8443","metrics":{"cost":602,"rank":82489,"domains":3,"nrWords":0,"traffic":32,"httpCode":403,"keywords":9,"refpages":5,"pageTypes":[],"topVolume":100,"urlRating":4,"topKeyword":"port 8443","domainRating":72},"isTarget":null,"attribute":null,"url_visual":"https://www.router-switch.com › faq › difference-betwe...","url_from_url_visual":false}],"siteLinks":[]}]},{"pos":5,"content":["organic",{"link":["Some",{"url":["Url",{"url":"https://developer.mozilla.org/en-US/docs/Glossary/Port","input":{"mode":"exact","protocol":"https","signatureInfo":{"notAfter":"2026-11-11T19:50:28Z","signature":"lgQf4w9T+1kLrpu/qq58Dmtql7HSSVF4NylO82xVc6M="},"protocollessUrl":"developer.mozilla.org/en-US/docs/Glossary/Port"}}],"title":"Port - Glossary - MDN Web Docs - Mozilla","metrics":{"cost":47,"rank":26,"domains":68,"nrWords":1545,"traffic":12,"httpCode":200,"keywords":8,"refpages":208,"pageTypes":[["Article","Definition"]],"topVolume":250,"urlRating":4,"topKeyword":"http port","domainRating":96},"isTarget":null,"attribute":null,"url_visual":"https://developer.mozilla.org › en-US › Glossary › Port","url_from_url_visual":false}],"siteLinks":[]}]},{"pos":6,"content":["organic",{"link":["Some",{"url":["Url",{"url":"https://elementor.com/blog/https-port-a-comprehensive-guide/","input":{"mode":"exact","protocol":"https","signatureInfo":{"notAfter":"2026-11-11T19:50:28Z","signature":"6KNITUbU0vbToVLKbjGLjb4l/7CJsqUpnFk5vZBqU64="},"protocollessUrl":"elementor.com/blog/https-port-a-comprehensive-guide/"}}],"title":"HTTPS Port: A Comprehensive Guide to Secure Web ...","metrics":{"cost":73,"rank":318,"domains":2,"nrWords":4519,"traffic":15,"httpCode":200,"keywords":9,"refpages":3,"pageTypes":[["Article","Guide"]],"topVolume":500,"urlRating":4,"topKeyword":"https port","domainRating":92},"isTarget":null,"attribute":null,"url_visual":"https://elementor.com › Blog › Resources","url_from_url_visual":false}],"siteLinks":[]}]},{"pos":7,"content":["videos",[["Some",{"url":{"url":"https://www.youtube.com/watch?v=zxOurTF1GOc","input":{"mode":"exact","protocol":"https","signatureInfo":{"notAfter":"2026-11-11T19:50:28Z","signature":"2l3KrN5ZPe4SruFmyr9tnBXmQRZ2IHJCydfH691JTxo="},"protocollessUrl":"www.youtube.com/watch?v=zxOurTF1GOc"}},"title":"What Port Does HTTP Use By Default?
