How do I activate OpenKeychain in K9-Mail?

+

To use OpenKeychain with K9-Mail, you want to follow these steps:

+
    +
  1. Open K9-Mail and long-tap on the account you want to use OpenKeychain with.
    2. +
  2. Select "Account settings" and scroll to the very bottom and click "Cryptography".
    3. +
  3. Click on "OpenPGP Provider" and select OpenKeychain from the list.
    4. +
+

Thats it.
