Encryption layer for a client server protocol and transport -- 3

We are developing a backup and monitoring system which is based on a client (Windows) and server (Windows Server).

On the client end we have already implemented sqlite3 with CppSqlite3U (since we found many problems with international text when we used just sqlite3).

On the server we use SQL Server.

Our protocol is based on TCP/IP.

We sync the database and files between the client and the server.

The project:

- Adding an encryption later for our Transport class.

- Decrypt ./ Encrypt contents on the server side, taking into consideration that we don't use sqlite3 for the server. We use MS SQL Server.

- Decrypt / Encrypt files and not just the database.

Skills: ASP.NET, C++ Programming, Software Architecture, SQLite
