  Modern software engineering trends towards Cloud-native software development
by international teams of developers. Cloud-based version management services,
such as GitHub, are used for the source code and other artifacts created during
the development process. However, using such a service usually means that every
developer has access to all data stored on the platform. Particularly, if the
developers belong to different companies or organizations, it would be
desirable for sensitive files to be encrypted in such a way that these can only
be decrypted again by a group of previously defined people. In this paper, we
examine currently available tools that address this problem, but which have
certain shortcomings. We then present our own solution, Encrypted Container
Files (ECF), for this problem, eliminating the deficiencies found in the other
tools.
