Secure Text Transfer Using Diffie Hellman Key Exchange Based on Cloud

Encryption is the technique of hiding private or sensitive information within something that appears to be nothing be a usual. If a person views that cipher text, he or she will have no idea that there is any secret information. What encryption essentially does is exploit human perception, human senses are not trained to look for files that have information inside of them. What this system does is, it lets user to send text as secrete message and gives a key or a password to lock the text, what this key does is, it encrypts the text, so that even if it is hacked by hacker it will not be able to read the text. Receiver will need the key to decrypt the hidden text. User then sends the key to the receiver and then he enters the key or password for decryption of text, he then presses decrypt key to get secret text from the sender. Diffie-Hellman key exchange offers the best of both as it uses public key techniques to allow the exchange of a private encryption key. By using this method, you can double ensure that your secret message is sent secretly without outside interference of hackers or crackers. If sender sends this cipher text in public others will not know what is it, and it will be received by receiver. The system uses online database to store all related information. As, the project files and a database file will be stored into the Azure cloud, the project will be accessed in the web browser through Azure link.
