Good questions, Inthane. I hope the improved documentation clarified
things a bit. This is not intended to be a comprehensive encryption
tool, but a free one that enables certain techniques built into the
Windows API. If a computer crashed, a file encrypted in this way would
not be readable on another computer, so it is not good for backup
purposes.
Primarily, I envision it as being useful as a component that developers
can use when encrypting sensitive data within an application. Although
I made the documentation generic, I also hope it will be useful as an
example of writing a simple console mode program in VBNET.
If there is enough interest I could add a GUI later (or since it is open
source, someone else could contribute that). Someone informed me that
choosing an encryption property for a file from the context menu in
Windows Explorer can do a similar thing. I was not aware of this
before, but that may be a GUI way of doing something like this.
Cheers,
Jamal
