Das ZUGFeRD-PDF ist valide. -> Signatur: unknown

[m4Viper]

Hello everybody,

validating my created ZUGFeRD PDF says -> pdf valide, but shows the message: "signature: unknown"

Needs my zugferd-pdf a signature or can this message be ignored?

Hi,
no, not at all, signature of the authoring software, that is for statitical purposes only and could e.g. ghostscript in case there are clues that that was used as the Factur-X attaching software.

kind regards
Jochen
