Thanks Pedro, actually I understand cryptography and I agree with you. Sonebody replied to me off-list and wrote me about ProtonMail <https://protonmail.ch/>, actually they are doing exactly what I wanted (I think), so maybe I will try to cooperate with them and/or use their open source source code. Anyway thanks for the feedback!
