Good security is safe in spite of knowing exactly how it works. While revealing the exact details does not make an algorithm less vulnerable, it should not make it more so.

And if it turns out that you are using a flawed solution, talking about it early will, at the very least, get people to yell at you as to what you should do instead.

In this age, the best security algorithms are usually the one most talked about. The more you test it and the more people you get to look at it and write theorems and papers about size of the search space, results from various attacks and so forth, the better.
