An application for end to end secure messaging service on Android supported device

Nowadays the easiest way to connect with people is chatting by using Mobile Chatting Applications which offers us a lot of helpful facilities. Though different Chat Applications offers different security to users but leads to increase in vulnerabilities & risks of attack on data. Not only for business conversations also for normal conversations our data must be secured because, someone's data is very sensitive & data security is most important to prevent unwanted hacking or unwanted data losses. To overcome this kind of vulnerabilities & risks of attacks on data we must need encrypted messaging protocol for a secured conversation. This proposed protocol uses a user define password for SHA-2 hash generation. SHA-2 Hash Generation is used as key of AES-256 encryption to encrypt the message during transmission of message. In this module of security the software encrypted message only can be decrypted by user in time of accessing the conversation by introduction of the encrypted user's define key. Using this whole system you can share data without any hesitation because; through this approach of encryption it can create more powerful security for data transmission across the Earth.
