PDF - Sign

Overview

The 'PDF - Sign' action applies a digital signature to the PDF document provided. The action provides two signing options:

The 'Standard' option uses Encodian's 'Adobe Approved Trust List' certificate, thus a signed document will appear as an approved signature with long-term-validation enabled (the signature image is optional).

The 'Custom' option allows you to provide a custom certificate in PFX format which is used to sign the document. The validity of the signature will depend on the certificate provided to sign the document.
