Difference between HTTP and HTTPS

Prerequisite – Difference between http:// and https://

1. HyperText Transfer Protocol (HTTP): HyperText Transfer Protocol (HTTP) is a protocol using which hypertext is transferred over the Web. Due to its simplicity, http has been the most widely used protocol for data transfer over the Web but the data (i.e. hypertext) exchanged using http isn’t as secure as we would like it to be. In fact, hyper-text exchanged using http goes as plain text i.e. anyone between the browser and server can read it relatively easily if one intercepts this exchange of data. 

2. Hypertext Transfer Protocol Secure (HTTPS): Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It is used for secure communication. In HTTPS, the communication protocol is encrypted using Transport Layer Security.
Difference between HTTP and HTTPs :

S.No.	HTTP	HTTPS
1.	HTTP stands for HyperText Transfer Protocol.	HTTPS for HyperText Transfer Protocol Secure.
2.	In HTTP, URL begins with “http://”.	In HTTPs, URL starts with “https://”.
3.	HTTP uses port number 80 for communication.	HTTPs uses 443 port number for communication.
4.	HTTP is considered to be unsecure.	HTTPs is considered as secure.
5.	HTTP works at Application Layer.	HTTPS works at Transport Layer.
6.	In HTTP, Encryption is absent.	Encryption is present in HTTPS.
7.	HTTP does not require any certificates.	HTTPS needs SSL Certificates.
8.	HTTP does not improve search ranking	HTTPS helps to improve search ranking
9.	HTTP faster than HTTPS	HTTPS slower than HTTP
10.	HTTP does not use data hashtags to secure data.	While HTTPS will have the data before sending it and return it to its original state on the receiver side.
11.	In HTTP Data is transfer in plaintext.	In HTTPS Data transfer in ciphertext.
12.	HTTP Should be avoided.	HTTPS Should be preferred.
13.	Search engines do not favour the insecure website.	Improved reputation of the website in search engine.
14.	HTTP Does not require SSL/TLS or Certificates	HTTPS Requires SSL/TLS implementation with Certificates.
15.	In HTTP Users ar  worried about their data.	In HTTPS Users are  confident about the security of their data.
