The main purpose of the digital certificate is to ensure that the application belongs to the entity to which the certificate was issued. The Nitro PDF Software 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 Nitro PDF Software and verified by a trusted Certificate Authority (CA).
Nitro Pro (previously Nitro PDF Professional) is a commercial software application used for creating and editing portable document format (PDF) files. The product is intended for the professional market and runs on Microsoft Windows PCs. www.nitropdf.com
