Digital signature for PDF documents

- ... A valid personal certificate must be available.

- The certificate must be imported into the certificate store of the operating system.
- Navigate to the location of your certificate file and double-click on the certificate to start the certificate import wizard (Fig. 1).
- Select "Current user".
- Confirm by clicking on "Next" (Fig. 2).
- Confirm the next window with "Next".
- Enter the password for your certificate (certificate password that you also use when sending an encrypted mail).
- Deactivate all ticks except the last one.

In the "Keychain Management" app (Fig. 1) on the Mac, select either the "Login" or "System" keychain (Fig. 2).

Enter the name and password of an admin on this computer when prompted (Fig. 4).

Then click on "Next".
