🍪What are cookies?🍪
In short:- Cookies are files that contain small pieces of data — like a username and password — that are exchanged between a user's computer and a web server to identify specific users and improve their browsing experience.
1) Cookies are the piece of text that a Web server can store on a user's device, hard disk etc.
2) It is a message that web servers pass to your web browser when you visit any Internet sites like Amazon, Facebook, YouTube, etc.
3) Cookies allow a Web site to store information on a user's machine so that you can retrieve it later. Your browser stores each message in a small file called cookie.txt.
4) When you request another page from the server, your browser sends the cookie back to the server. These files typically contain information about your visit to the web page, as well as any information you've volunteered, such as your name and interests. The piece of information are stored as name-value pairs.
➡️📲 For example, a Web site might generate a unique ID number for each visitor and store the ID number on each user's machine using a cookie file.
➡️🖥️ If you use Microsoft's Internet Explorer to browse the Web, you can see all of the cookies that are stored on your machine. The most common place for them to reside in a directory called c: windows cookies.
➡️ You can see in the directory that each of these files is a simple, normal text file. You can see which Web site placed the file on your machine by looking at the file name (the information is also stored inside the file). You can open each file by clicking on it.
➡️ For example, I have visited https://myplanetknowledge.blogspot.com, and the site has placed a cookie on my machine. The cookie file for myplanetknowledge.com contains the following information:
➡️ UserID A9A3BECE0563982D https://myplanetknowledge.blogspot.com
Myplanetknowledge.com has stored on my machine a single name-value pair. The name of the pair is UserID, and the value is A9A3BECE0563982D. The first time I visited myplanetknowledge.com, the site assigned me a unique ID value and stored it on my machine.
📝 (Note that there probably are several other values stored in the file after the three shown above. That is housekeeping information for the browser.)
For the most part, cookies are not harmful. They’re just another protocol used on the internet to facilitate communication between users and servers. Cookies cannot carry viruses or malware, nor can they transfer malicious programs to other users.
❓ So, what should you worry about? The worst possible scenario would be the interception or forgery of one of your cookies, which would allow another user to impersonate you on some website. This could result in them eavesdropping on your user data or hijacking your account credentials.
➡️ However, there’s no need to worry. Cookie security mostly depends on the website and your browser; a cookie encryption feature, for example, can help protect you from hackers.
➡️ A more prevalent issue is a specific type of cookie called the “tracking cookie.” These cookies do not have your wellbeing in mind. Instead, they keep track of all of your actions on certain websites.
