What is https and the different with http


HTTP means Hypertext Transfer Protocol. 

It is the underlying protocol that is being used by the World Wide Web. 

HTTPS on the other hand, means Hypertext Transfer Protocol over SSL (Secure Sockets Layer). 

It combines Hypertext Transfer Protocol with Transport Layer Security/Secure Sockets Layer (SSL/TLS); it is considered the more secure version of HTTP. 

What it does is it sends the data over the web in an encrypted and secured manner. 

It protects the data from being intercepted while it is being transmitted over the World Wide Web.  

It is often used by online banking web sites and by other websites where transmitted data needs to be secured and protected.

HTTP (Hyper Text Transport Protocol) is transmitted through this port 80 (TCP).

When we do browsing in our browser then Normally use HTTP problem with it this is not much secure. so someone can eavesdrop on the conversation between your computer and the web server.

HTTPS (Hypertext Transfer Protocol over Secure Socket Layer, or HTTP over SSL): This is a web protocol it is created by Netscape its security is strong it encrypt and decrypt user page that we put in our browser that are returned by the web server.

HTTPS is really just the use of Netscape's Secure Socket Layer (SSL) as a sublayer under its regular HTTP application layering. (HTTPS uses port 443 instead of HTTP port 80 in its interactions with the lower layer, TCP/IP.) SSL uses a 40-bit key size for the RC4 stream encryption algorithm,new-age browsers use 128-bit key size which is more secure than the former, it is considered an adequate degree of encryption for commercial exchange.

HTTPS is normally used in login pages, shopping/commercial sites.

Therefore we can say that it may be encrypted browsing pages but its don’t mean that it is safe.

There are tools out there to decrypt the information being sent over the wire, although its more difficult to do so.

HTTPS stands for “HyperText Transport Protocol Secure.” HTTPS is the same thing as HTTP, but uses a secure socket layer (SSL) for security purposes. Some examples of sites that use HTTPS include banking, Gmail  and  corporate websites and most websites that require you to log in such as Face Book.

When you use https in your web browser a new secure layer called SSL (secure socket layer) does the data transmission using an encryption standard: DES, RSA etc.

Once your web traffic pass through https, if any one capture data packets using any packet analyzing software, they will not be able to understand what is actually pass through between your computer and the web server  significantly reducing the probability of an attacker sniffing our sensitive web data like credit card and mail information.

Therefore HTTPS protocol is the most safest way till date for online banking, transactions and funds transfer.

Very interesting post to discuss with.

HTTPS is a combination of HTTP and SSL/TLS protocol to provide the secure identification for a network and encrypted communication. Usually these https networks are used for payment gateways and its sites for secure transfer of the data.
HTTPS is another secure layer to protect the traffic so that the user trusts their browser software correctly implements HTTPS.

The website provides the valid certificate which means it is signed by the trusted authority
Here browser integration of HTTPS site is also very important ,most of the old browsers display a warning they receive invalid certificate.New browsers also prominently display security information in the address bar.

A green color can be seen the address bar for the trusted and extended valid https sites.

Differences are

  • Default port of http is 80 and 443 for https
  • Http works by transferring normal http instructions through an encrypted system.
  • When using a secure connection the server responds to the initial connection by offering a list of encryption methods.
  • And its client and server exchange certificates authenticates the identities.
  • A server should have a public key certificate which resembles the key information with owner's identity and are mostly of third party .

Let me know for any further information for this post
