2 Differentiate HTTP and HTTPS?
HTTP stands for “Hyper Text Transfer Protocol.” Almost all websites use it to send data, which is what makes hyperlinks possible. The HTTP protocol utilizes TCP port 80, while HTTPS is the secure version of HTTP. HTTPS enables us to verify the identity and low-level encryption through TCP port 443.
What is HTTPS?
Secure HTTP or HTTPS is used for designing identity verification. HTTPS utilizes SSL certificates to verify whether the server you are connecting to is the one it says. While HTTPS has an encryption capability, it is generally considered insufficient; moreover, encryption methods are required whenever possible. HTTPS traffic goes on TCP port 433.
