+# Sending bulk LinkedIn Connection requests
+
+Scripts in JavaScript to send and reject bulk connection requests
+
+1. Open your browser and login into your Linkedin account.
+2. Navigate to ```linkedin.com/search/results/people/```.
+3. Launch Developer Tools in your Chrome browser
+
+Go to your Chrome , and under the Developer Tools. For Windows / Mac , you can press F12 function key. Alternatively the short cut keys for Windows is “Control + Alt + I”, for Mac it is “Option + Command + I”. If you prefer to use the mouse instead, point to the hamburger menu (the 3 dots) on the Chrome top right corner. Click on it and the Developer Tools is in here

+7. Now copy the whole code and paste it into the console section.
+8. Wait for the script to do its job.

+# Caesar Cipher- Cryptography with Python
+
+## Overview:
+
+Caesar Cipher is one of most easiest and simplest encryption methods. It is a stype of substitution cipher.
+It works by shifting each character of the input string by a given value down the alphabetical order.
+
+Example: Upon giving a shift key of 2, A would be replaced by C, B by D and so on.
