This repository does not contain entire of source code, but core part is archived to say what I wanted to do with this.

Warning

The initial build of rensenWare (also initial release of source code) has no exception handlers, so it can be terminated unexpectedly and results permanent data loss.

SO PLEASE, DO NOT EXECUTE IT IF YOU ARE NOT SURE THAT YOUR DATA IS SAFE FROM RENSENWARE UNDER ANY CIRCUMSTANCES!

Also, DO NOT request me the entire(or encryption part) source code of rensenWare. I decided not to provide it to anyone.
