The main purpose of the digital certificate is to ensure that the application belongs to the entity to which the certificate was issued. The Cinnamon Software Inc. digital certificate does not guarantee that a signed application is safe to run, but rather informs the user that the software was digitally signed by Cinnamon Software Inc. and verified by a trusted Certificate Authority (CA).

“Cinnamon Software is a developer and publisher of quality programs for users of Windows® computers. We currently offer several programs that you can download, use, and copy free of charge. Each program comes with full install and uninstall capabilities, and includes user help where possible and appropriate. This software is written by geeks for non-geeks. If you're looking for the other kind you may be disappointed, but please don't complain, this software is simply not made for you.”
