Speed and safety! In this era, the two most important factors in any application are the rapid transfer of data between backend, user interface, and security. React Native has been used to create hybrid apps with an easy-to-use interface.
I used this cross-platform for mobile devices to design my “End-to-End Encrypted Voice Calling App for Smartphones”, which has the slogan “Type One, Use Everywhere”.
The primary purpose of the app is to create a very secure app. This uses an end-to-end encryption method and an open source signal protocol library to create a voice communication application using different encryption algorithms.
In addition, in the design of the application, not only is it planned to transfer security data in the internet environment, but I have planned to open the application with a face print to increase the user's security in the real world with the ML kit from Google.
While I traveled researching how to build and build this app, I learned the following; Although the cryptography branch is not a broad one, its importance is very great. Encryption algorithms consist of the same concepts on their basis. With change, the performance of algorithms can be improved in terms of security or speed.
There are different encryption algorithms according to my research and the conclusion that I came to in my design, depending on the application that will be designed and the environment in which the application will operate, the encryption algorithm used will play a major role in the performance of the application.
Creating something from scratch isn't always a good idea, so ready-made open source libraries - like the Signal Protocol Library - that exist make it easier for us as a cryptographic designer and take Internet security to a higher level.
Encryption algorithms can and should be combined with current and new technologies such as React Native to create modern high-performance applications.
As a result, the "end-to-end encrypted voice calling application for smartphones" was designed using the React Native Cross platform and signal protocol. SQLite Database and Firebase Cloud were used in the database design. It was decided to use the Google ML kit firebase library of machine learning for face recognition and the RSA algorithm to store the obtained data in a safe way.
We can see how easy it is to implement the end-to-end encryption method. Internet security and the security of people's personal information are of great importance, and people must be seriously aware of this problem, so that rulers and technology companies are forced to use this method.
