    Encryption On Every Other Email Platform

    We wont go through each provider individually, because the story is the same: You need to use a third-party tool to encrypt your emails. You might be thinking, sure, okay, Ive used third-party tools for things, how hard can it be?

    The most popular of these tools is GNUPG or Gnu Privacy Guard. GNUPG is free, and it allows you to encrypt your online data and communications such as email. Here are the next steps:

    1. Create your own public or private keypair using the GNUPG software.

    Lets stop right there for a second, because theres a lot going on in that one sentence. A keypair is a system of encryption whereby one party holds one key or line of code and the other party owns the other. When a message is sent and both keys are identified, the encrypted message is decrypted. Only by having the key can you access the encrypted data.

    To create your key, youll need to find the binaries and source code for whichever platform you want to encrypt your emails on. GNUPG and other third-party tools may provide these as well.

    2. Send your receiver the key youve created.

    Now you have to send the key, or list of long numbers, so they can do the same thing youve done and read your encrypted messages, or send you encrypted messages of their own. From there, we could also get into the creation of public or private keys, which basically means the public can search and access your key or not.
