Certificate guide

In software such as Adobe Reader, documents with digital signatures are automatically validated when opened. In Adobe Reader, it is displayed which certificates can be used for validation. If any certificates are missing, a yellow warning triangle is displayed for the digital signature.

To avoid the warning triangle, certificates can be imported into Windows and then used by Adobe Reader. After import, the digital signature is validated against the certificate and if done correctly, a green check mark will then be displayed.

The steps below describe how to install Comfact Signature certificates on a Windows computer and how to import the certificate into Adobe.
