Encryption, JAVA, C/C++ developer for secure APP

Hello, we need to increase the security of our existing application:

> Change certain parts in JAVA to C code

> Increase the cryptography in the code

> Increase the functions of application

> Increase the encryption of data and DB

Short intro:

We have a JAVA written communication application that we want to secure with a higher level of coding. The coding part of the application must contain:

- Remove existing commenting in the JAVA developments;

- Work with the existing cryptography inside the application;

- Increase the cryptography protocol of communication;

- Replace the existing JAVA code into C code at brute-force related areas:

1. Login

2. Registration

3. Content input

4. Content output

5. Database connections

6. Additional integration

- Replace the existing JAVA code into C code at important cryptography parts where the keys, certificates, etc. are stored in the code.

- Increase with C / C++ the obfuscation techniques.

The application is already up and running, located in- and outside the Playstore. Using our own servers to manage user accounts are located on-premise.

You will be in contact with one of the developers who worked previously on this project to guide you through the code. Next to that you have to learn also the code and operations. You will receive the APP name at the moment we discuss the project.

We have many more applications that need to be secured eventually, when this project goes well we invite you to other applications too.

Budget for this instant communication app to secure is around $750. Goal is ready in one month, the sooner the better.
