LetвЂ™s go into details on how to encrypt an email.

And if you want to send an encrypted email, a recipientвЂ™s certificate should be in your keychain. After that, youвЂ™ll be able to send signed emails.

Mail supports S/MIME, one of the most popular email encryption certificates, so all you have to do to encrypt mail in the Mail app is to get a certificate and add it to your keychain. AppleвЂ™s native Mail app makes it relatively easy. You can add encryption to your emails yourself. It might seem like email encryption is a complicated under-the-hood thing that is either there or not there. ThereвЂ™s also a private key on your computer that actually decodes the message, ensuring that only the right people can read each message. Both sender and receiver utilize something called a public key cryptography, which scrambles the emailвЂ™s contents into a coded string only the sender and receiver can decode. If you wanted to send secure notes, you might create your own encryption method only you and the recipient understood.Д®ncrypted email works the same way. It may not be able to stop people from intercepting emails, but it can prevent them from being able to read your messages. This is why encrypted email is so important. Someone could gain insight on very sensitive content, which could lead them to discover something you didnвЂ™t want them to know. Now, imagine if that sensitive note were intercepted.

That information is sent along to the recipient. When you create an email, youвЂ™re putting information into an app like Gmail or Mail. Here weвЂ™ll show you how to encrypt email, how to send secure email, and how some of the most popular email providers do (or donвЂ™t) secure your communications.
