Any security-related tool is only as good as its design
and implementation. Transparency means that, in
essence, all the moving parts are visible so you can judge
for yourself whether the tool merits your confidence. In
the case of a program, this means that source code must
be available, and that you can verify that the program
you're running corresponds to the source code provided.
