Which of our tools is giving you problems? (possible options: GPGMail, GPGServices, GPG Keychain Access, …)

GPG Keychain Access, i would say

What’s the version of that tool? (read the following knowledge base article to learn how to find a tool's version:


What version of OS X are you using? (e.g.: 10.8.4, 10.7.5)


Please describe your problem. Add as much detail as possible.

I have many e-mailadresses (i.g. Me and iCloud). Currently I have 1 public key for every one of them.

Please describe what you did expect instead

I found on Keyservers that there should be 1 signuture for 1 person, even for many e-mailaddresses. And a fellow student told me so as well.

If you remember, please describe the steps leading up to the problem

I activated a key for every e-mailaddress.

So can i have one public key for all my e-mailaddresses at once with GPG-Tools?

    This KB-article explains how to add more than one email address to an existing key. The email addresses in a key are called userIDs and you can add as many as you want.

    Important note: Note that all email addresses you add to a single key can be connected to one identity. Depending on your use-case this might be wanted or should be avoided. Please consider that first and then proceed.
