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:
- close all gpg applications and Mail.app
- open finder, press ⇧⌘G
- paste '~/.gnupg/gpg.conf' without the ' and click Go
- open gpg.conf with TextEdit
- add the following line at the end of the file
group staff@mywork.com = fingerprint1 fingerprint2 fingerprints
Whenever you now write to staff@mywork.com the message will be encrypted to all public keys you added the fingerprints of. Note that no valid key must exist for staff@mywork.com for the group feature to work as expected.
