The problem is that I will not have time for that in the next 3 weeks because of exams. I planned for this weekend some other minor/trivial changes that I think we need before jumbo release, but that's all what I can do at the moment. I added this task next to gpu pbkdf2-sha512 to my todo list. Lukas
