How to use the group feature to encrypt content to multiple public keys by using a single address

The group feature is relevant to companies or groups looking to encrypt content to various public keys of the group members while using a single email address as recipient.

To use the group feature:

  1. close all gpg applications and
  2. open finder, press ⇧⌘G
  3. paste '~/.gnupg/gpg.conf' without the ' and click Go
  4. open gpg.conf with TextEdit
  5. add the following line at the end of the file
    group = fingerprint1 fingerprint2 fingerprints

Whenever you now write to the message will be encrypted to all public keys you added the fingerprints of. Note that no valid key must exist for for the group feature to work as expected.
