Encrypting Email on OS X and iOS Tutorial

In this video I walk through the steps to encrypt email using S/MIME technology on OS X and then on iOS devices.   I leverage the Comodo email certificate service which is free and has no relationship to me.  To follow this tutorial you will need a Mac computer and an iOS device and email service.

Encrypted email can be used to meet privacy regulations, to protect whistle-blowing activity, to communicate commercial secrets using adversarial networks, or to communicate with foreign nationals in locations in which the state controls significant portions of the Internet infrastructure.

The focus of this tutorial is on connecting all the pieces between Keychain Access, and Apple Mail on iOS and OS X.  No programming is required.
