Mac OS X Mavericks: Integrate personal certificates into mail
With Mac OS X Mavericks, you can integrate personal certificates into Mail. These are required for sending encrypted or signed emails. We explain how to link Apple's mail with your personal certificate.
Use personal certificates in Mail on Mac OS X Mavericks
A certificate must be integrated into the keychain administration under Mavericks. To do this, follow the instructions:
- First set up a certificate for your email address with which you want to send signed and encrypted emails. To do this, you must contact the relevant certification body.
- After you've downloaded the certificate to your Mac, double-click the file. The certificate is then moved to the keychain administration.
- It is important at this point that the file must have an appropriate extension for certificates - for example ".p7c" or ".cer". Otherwise the certificate will not be copied to the keychain administration.
- Now enter "Keychain Access" in the spotlight search at the top right and select the first hit.
- At the bottom left click on the item "My certificates" (see picture).
- Your certificate should now appear in the list. Click on it and select "Always trust" under "Trust"> "When using this certificate".
- The certificate is now available for sending encrypted and signed emails.
