    2nd Question. What is the difference between HTTP and HTTPS?

    • Henry Dalziel

      Basically the difference is this: HTTP is Hyper Text Transform Protocol and is transmitted over the network via PORT 80 (TCP).

      The HTTPS (Hypertext Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is another Web protocol that was originally developed by Netscape and embedded into their browser that enabled encryption and decryption with regards to html page requests.

      HTTP uses port 80, HTTPS uses port 443.

      In addition, HTTPS/ SSL uses a 40-bit key size for the RC4 stream encryption algorithm, which is considered an adequate degree of encryption for taking credit card payments online.

    • Rashid Ansari

      Secure HyperText Transfer Protocol (HTTPS) is for all practical purposes HTTP. The chief distinction is that it uses TCP Port 443 by default, so HTTP and HTTPS are two separate communications. HTTPS works in conjunction with another protocol, Secure Sockets Layer (SSL), to transport data safely.
