Secure communications is when two entities communicate with each other and the communication is completely secured from a third party or the intruder. This type of communication process can be achieved using encryption and decryption mechanism. The implementation of Email encryption is performed with the intension of showing the working of encryption and decryption mechanism. This web application allows user to send an encrypted electronic-mail to any domain and it can be only decrypted using the receiver’s private key. Whereas, messaging android application was developed to replicate existing WhatsApp application to see whether, it performs end-to-end encryption or it’s not what it seems. The application allows users to securely communicate with each other via performing actual end-to-end encryption.
