HTTPS (Hyper Text Transfer Protocol Secure)
Hypertext Transfer Protocol (HTTP) is a protocol where communication happens in clear text. To ensure authenticity, confidentiality and integrity of messages Netscape designed HTTPS protocol. Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol (HTTP) with the SSL (Secure socket layer)/TLS (Transport layer security) protocol. It provides encrypted communication and secure identification of a network web server. HTTPS encrypts and decrypts the page requests and page information between the client browser and the web server using a secure Socket Layer (SSL). HTTPS by default uses port 443 as opposed to the standard HTTP port of 80. URL's beginning with HTTPS indicate that the connection between client and browser is encrypted using SSL.

Decoding ROT using the Echo and Tr Commands in your Linux Terminal
ROT which is known as the Caesar Cipher is a kind of cryptography wherein encoding is done by moving the letters in the alphabet to its next letter. There are 25 possible ROT settings which covers the scope of letters A-Z. Thus in ROT-1, A is equals to B and B is equals to C and so are the next letters but Z would go back to A. And so the ROT-1 cipher of ‘ProjectX‘is ‘QspkfduY‘. Thus, ROT = rotation. In this short write up we will be using the echo and tr bash commands in your Linux terminal to encode or decode letters using ROT cipher. The ‘echo’ command is a built-in command in Bash in C shells which repeats the letters of words after it.


Protect your privacy online with ’TOR’
Let’s begin with what Tor means: The Onion Router. A router is a device that handles your request to go from your home, office, mobile connection to a website or a web service. If you write in your browser URL bar http://chmag.in and hit return, you’ll send your request to your ISP router, which will send the request to another router and so on, until you reach the CHmag ISP router, and finally get your page back. Every one of these steps is called a “hop”.


Firewall 101
Today we are exposed to innumerable threats online. Firewalls act as the first line of defense for securing our network against these threats. Firewall could be a program or a device or group of devices used to control the traffic flow. The basic principle that Firewall uses to control this communication is ‘Access Rules’. It maintains an access rule table and every time a packet comes in or goes out, Firewall refers to this table. It only allows authorized traffic and blocks the unwanted packets.
