Another thing that I really like is PCP. PCP is tool that allows the user to encrypt their email. I think that this is so important because usually, emails pass through different servers and network before their reach their intended destinations. While they are traveling, hackers can see what I am writing someone else, which violates my privacy. By encrypting my emails, someone can't see what I am actually writing. The only person that can see it is the intended receiver of the email because the PCP decrypts the email. I think that this is so cool. Maybe I am naive, because I automatically assumed that emails were private because I wasn't sending it publicly, but I am going to start giving people my PCP KEY.
