NetLib 6.5 will allow you to use FiveWin or Clip4Win to create Windows 3.1 compatible products. These programs can run unchanged under Windows 95.
10. Is it possible to break NetLibs encryption?
NetLib's SDE was designed to be a moderately secure scheme to keep unauthorized users and programmers from accessing data. It was not designed to foil the skilled, dedicated hacker.
