摘要：Encryption is the idea of hiding information that could be private or sensitive in nature within something that appears to be nothing unusual. Anyone who views the ciphertext will have no idea that there is any secret information. Encryption exploits human perception, as humans are not trained to look for files that have information inside of them. What this system does is that it allows the user to send text as a secret message and gives a key to lock the text. This key encrypts the text so that even if the transferred file is compromised by a third party, they would still not be able to read the text. The receiver will require the key to decrypt the encrypted text. The sender shares the key with the receiver which will then be used by the receiver to decrypt the ciphertext given by the user. The Diffie-Hellman key exchange algorithm offers the best of both worlds as it uses public-key cryptography to allow the exchange of a private key which will be used for encryption. By using this method, we can ensure that our secret message is sent secretly without the interference of hackers or crackers. If the sender sends this ciphertext in a public network others will not know what it is, and it will be received by the receiver. The system uses an online database to store all the required information. As the project files and a database file will be stored in the remote MySQL cloud, the project will be accessed in the web browser through a cloud link.
