HTTPS is encrypted HTTP, and the only difference between the two protocols is that HTTPS encrypts normal HTTP requests and responses using TLS (SSL). HTTPS is therefore much more secure than HTTP: the URL of a website using HTTP is http://, while the URL of a website using HTTPS is https://.
What is HTTP?
HTTP stands for Hypertext Transfer Protocol, which is a protocol for transferring data over the Internet, i.e. a prescribed order and syntax for presenting information. Much of the information sent over the Internet, such as website content and API calls, uses the HTTP protocol. HTTP messages consist of two basic types: requests and responses. HTTP requests are generated by the user’s browser when the user interacts with a web property.
What is HTTPS?
HTTPS stands for Hypertext Transfer Protocol Secure (HTTP over TLS or HTTP over SSL). When you type “https://” in front of a domain name in the address bar, you are instructing your browser to connect via HTTPS. Usually, websites that use HTTPS are redirected, so typing http:// will redirect you over a secure connection, although HTTPS also uses the Transmission Control Protocol (TCP) to send and receive packets. Sending and receiving is done over port 443 over a TLS (Transport Layer Security) encrypted connection.
Advantages of using HTTPS
The security advantages mentioned above – authentication of the server’s identity, encryption of data transmission and protection of communications against tampering – are clearly the most important advantages of using HTTPS.
Website operators need to protect visitors’ data (HTTPS is a PCI data security standard requirement for any website that collects payment data) and website visitors want to know that their data is being transmitted securely.
How do I switch from HTTP to HTTPS?
First you need to decide whether you need a single, multiple or wildcard certificate. Then you need to use a 2048-bit key certificate so that the web server can accept the certificate signing request. You must ensure that you keep your SSL certificates up to date. Use appropriate URLs for resources in the same security domain. Use HTTP 301 redirects on the server side – mod_rewrite is common – to redirect to HTTPS pages. Make sure to include access to HTTPS pages for web crawlers in your robots.txt file.
Make sure your site returns the same HTTP status code To summarise. Website owner’s responsibility to protect user data Switching from HTTP to HTTPS has many advantages, both in terms of security and business promotion HTTPS allows you to compete in Google’s rankings and use the latest technologies (push notifications and PWAs).
