A virtual keyboard does not mitigate the vulnerability to key loggers
or similar sniffing technologies. One could still be able to observe
the data exchange between processes as long they are not isolated.

I don't think GPG should start to mangle with other data formats.
ImageMagick does the trick. Why should we invent the wheel a second
