I'm a 17-year-old high schooler. I really love free software, but I don't think there are a lot more things that I like.

comment Is there need for message authentication if a public key is transmitted and then used to encrypt a symmetric key?
Great, thank you! I have approved your answer. Just out of curiosity, what aspects make this a naive protocol? With my limited knowledge I wasn't able to deduce that and would use this in a production environment so I would really like to know where it particularly errs.

Thanks for the answer, it covered all of my questions, but there is one thing I don't understand--how can someone watching the user see her public key if it is encrypted using the server's public key? Isn't the server the only party that could decrypt it and see the user's public key? Would you be so kind as to clarify this?
