This makes communication over the an unsecure medium, such as public Wi-Fi, highly vulnerable to interception. When information is sent over regular HTTP, the information is broken into packets of data that can be easily “sniffed” using free software. HTTPS prevents websites from having their information broadcast in a way that’s easily viewed by anyone snooping on the network. Why is HTTPS important? What happens if a website doesn’t have HTTPS? Information that’s encrypted by the public key can only be decrypted by the private key. The public key - this key is available to everyone who wants to interact with the server in a way that’s secure.This key lives on a web server and is used to decrypt information encrypted by the public key. The private key - this key is controlled by the owner of a website and it’s kept, as the reader may have speculated, private.This type of security system uses two different keys to encrypt communications between two parties: This protocol secures communications by using what’s known as an asymmetric public key infrastructure. The protocol is called Transport Layer Security (TLS), although formerly it was known as Secure Sockets Layer (SSL). HTTPS uses an encryption protocol to encrypt communications. You can use the Cloudflare Diagnostic Center to check if a website is using HTTPS. Web browsers take HTTPS seriously Google Chrome and other browsers flag all non-HTTPS websites as not secure. Look for a green padlock in the URL bar to signify the webpage is secure. In modern web browsers such as Chrome, websites that do not use HTTPS are marked differently than those that are.

This is particularly important when users transmit sensitive data, such as by logging into a bank account, email service, or health insurance provider.Īny website, especially those that require login credentials, should use HTTPS. HTTPS is encrypted in order to increase security of data transfer. Hypertext transfer protocol secure (HTTPS) is the secure version of HTTP, which is the primary protocol used to send data between a web browser and a website.
