I'm building a desktop application that's used to manage secret files or sensitive files.
Ideally, application help to store, manage and manipulate important files.
Our target is a developer or system admin who uses our application to save their SSL certificates or important files for their server or backend system.
So, I need a logo for this application, no text logo, no 3D, flat or simple is my suggestion. The logo should show the main idea of simple and secure.
My favourite colours are #080808, #121212 #F2F2F2, #d2d2d2 #bdbdbd or #aaaaaa. But feels free to use what you want to fit with the ideas.
