I disagree. If it's based on a tried and tested (and occasionally formally verified) crypto system, knowing the algorithm doesn't lead to a crack. Weaknesses would come through bugs in the framework (or incorrect application of it), and the more people who can see the source the greater chance there is that good people as well as bad can find the issues. Good people fix 'em.
Cheers,
Graham.
