To secure an email, first you need to purchase a secure signing certificate from a 3rd party company (like Verisign, Thawte Communications and alike). They would primarily be in .p12 format (PKCS12 file format). Once you have obtained a security certificate, you need to import this by either double clicking on the .p12 file, or, by dragging the file inside the Keychain application icon found in Applications > Utilities. Exit the Keychain Access then open your mail and the security key is now available for you to use. To sign a message, you only need a private key. When you go in the Compose window, click on the icon 
 to sign the message. A signed message will show this line above the mail: 
To encrypt an email, you need to have both the private key of the sending mail and public key of the recipient. In the compose window, this means 
 mail will be encrypted, and this is not encrypted 
. And that's it! You already have your mails encrypted.
