 In this blog, I will generally talk about how to use proper tools to monitor SSL traffics of a mobile devices. Currently, I only can dealing with those SSL traffics which use an obviously certification. Some applications may not using system root cert or they doesn't provide us a method to modify their own certs. For these situation, I still didn't find a good solutions for it. But I'll keep updating this if I get one.
