Best regards, -- Jeremie Le Hen I wouldn't say that we favor code from any one project over another, every situation is different. In this case, I'm personally rather indifferent - both RNGs should supply good entropy. Arc4 may be a bit faster (I don't know if anyone has benchmarked by how much), so for this purpose it would seem to be the one to use. I can commit any patches you have after the 6.0 code freeze ends, which should be in the next few weeks. (It can be MFC'd to 6.0 and 5.4 after that as well.)
