SEE: (TechRepublic) Signing and encrypting email One of the reasons why I opt to use the GPG Suite on Mac is because it integrates seamlessly with Apple Mail. There is no need to manually encrypt/decrypt email, using keyboard shortcuts. However, in order to encrypt an email to a contact, you will have to import their public key into GPG. To do this, either have them send their public key to you or download it from one of the many public keyservers (if that's an option for your contact).
It is OK to give out your public key to others. Conversely, you should never give your private key to anyone unless you want them to be able to read your encrypted email or files. For further reading see the. Is a free, open source, cross-platform email client developed by the Mozilla Foundation.

If you lose it, you will no longer be able to read the e-mails encrypted using this key. We recommend ‘exporting’ your GPG key pair and storing a copy on an external data storage device. If someone would like to send you encrypted e-mails, just send them the public part of your GPG key.

October 11, 2013 This document is intended to help people quickly get started encrypting their email on Mac OS X Some background: This tutorial will guide you through installing and configuring several pieces of software which can be used to protect the content of your email from interception by 3rd parties by using encryption. During this tutorial you will generate a 'key pair' for encrypting files. The key pair consists of two parts: the public key and the private key. The public key is used to encrypt plaintext or to verify a digital signature; whereas the private key is used to decrypt encrypted text or to create a digital signature.
