 Hello everyone, my name is Sarkar. So, I will say the problem statement first and then I will tell you how my application idea came up. So, there are a lot of enterprise applications out there that are basically for example, there are banking applications and there are other sort of applications that do different things. But the main purpose of these applications is security and when it comes to saving files on the device, hopefully these applications need to implement encryption for these files because an android other applications can also access these files. So, the job of these applications is not basically to implement encryption, their job is to do other things. So, what I intend to do at the end of this hack night is to create a library that would encrypt these files for the applications. Now, this library would do it on a background service on a synchronous thread in the same application process or on the main thread. Now, these would be the configuration provided to the application and the application should be able to just call a simple method from our library and be able to encrypt a file onto the device. Also, I intend to create a demo application that should be using this library and the demo application would be a sort of file manager that you can browse through different files on the device and encrypt a particular file and save it where you want to. So, that is my application idea and well, I am looking for teammates or anybody who wants to join, maximum of one or two sources would be needed. Thank you.
