S/MIME Encrypted Email Example with Gmail and Comodo

A quick how-to installation for secure S/MIME installation for a Gmail account on macOS. This certificate can be used to simultaneously encrypt and sign emails.

Obtain and install an S/MIME Certificate

0. Create a unique revocation passphrase in a password manager—long, random, unique.
1. Browse to Comodo and request a free, secure email certificate:

• Enter your name, email address, and specify the maximum 2048 bit length
• Enter your revocation passphrase in case your private key is ever stolen or compromised

This describes my basic Arch Linux installation on my Chromebook Pixel.

Note: I'm a coward, so I installed Arch to an SD card instead of wiping out the existing SSD.

Requirements

• SD card. A very minimal Arch installation with XFCE will need about 2GB, so I think 4GB is the minimum you can get by with.
• Arch installer on a USB drive. The 2013.05.01 is broken with the recent netctl change. So either get an older or newer one.
• Some Arch Linux familiarity.
• Time, patience, and good eyesight.
