In a digitally signed filed there are two signed fields that are not reconized when this files is opened on Adobe Acrobat Reader, but if the same file is opened on a browser these two signatures shows normally.

The screenshot below show on the left the file when opened on browser and on the right when is opened on Adobe Acrobat Reader

Could you please help me to solve this issue?

 

Português

Em um arquivo assinado digitalmente, há dois campos assinados que não são reconhecidos quando esse arquivo é aberto no Adobe Acrobat Reader, mas se o mesmo arquivo for aberto em um navegador, essas duas assinaturas serão exibidas normalmente.

A captura de tela abaixo mostra, à esquerda, o arquivo quando aberto no navegador e, à direita, quando aberto no Adobe Acrobat Reader

Você poderia me ajudar a resolver esse problema?

Hello, @S. S 

 

The workarround for this issue is to open the file via a web browser, so signatures are shown.

 

Thanks again for you time and help.

Even using Adobe DC the issue remains the same

This most likely is due to an error in the PDF file. A minor error allowing some PDF viewers to ignore or repair it, but an error nonetheless.

Can you share the signed file for analysis?

Hi @Edson_Silva78,

 

Hope you are doing well. Sorry for your experience with Acrobat on signatures.

 

This issue is observed only when the signatures' key figures are outdated or a corrupt signature file is used (as suggested above).

 

In such scenarios, it would be really helpful if we could get a sample file for a further deep dive into the situation.

 

Also, about the browser situation, web browsers tend to bypass a lot of security checks, which Acrobat does not, and if such an issue is observed on digital signatures, Acrobat would most definitely flag it.

Look forward to hearing from you.


Regards,
Souvik.
