@Vanêide37659716cbla when youa re dealing with government PDFs with signatures, you might not have full security clearance to do so. There is a reason for these signatures. These signatures can involve complex cryptographic algorithms and embedded certificates. In Adobe Acrobat, try validating the digital signature. There should be an option to check the signature's validity and certificate information. Look for any error messages or warnings during the validation process.  Ensure that the certificate authority (CA) that issued the .gov.br signatures is trusted by your PDF viewer. You might need to add the CA's root certificate to your trusted certificate store.

I would double check with the Brazilian government's support or IT department responsible for digital signatures and they can provide information about compatibility requirements and potential solutions.

Hello!

 

I hope you are doing well.

 

Have you tried the suggestions shared by our community experts? You may also try the following suggestions and let us know how it goes: 

Validate Digital Signatures:

  • Open the PDF in Acrobat, go to Signatures and select Validate All. This will check the validity of the digital signatures and display any errors or warnings. See this article for more information: Validating digital signatures, Adobe Acrobat

Import https://adobe.ly/43ElzOc Certificates:

Download the https://adobe.ly/43ElzOc certificate chain from the official site.
Open Acrobat, go to Edit > Preferences > Signatures > More under Identities & Trusted Certificates.
Click Trusted Certificates > Import, select the downloaded certificate file, and click Open

Check Certificate Authority:

Ensure the certificate authority (CA) that issued the https://adobe.ly/43ElzOc signatures is trusted by your PDF viewer. You might need to add the CA's root certificate to your trusted certificate store

 

I hope this helps.

Thanks,

Anand Sri.
