PDF with a qualified electronic signature

[Robert_Mueller]

Hi,

Is there a way that sandblast wont remove or ignore PDFs with a qualified electronic signature (compliant to EU Regulation No 910/2014).. At the moment the "Threat Extraction" removes the signature and recreates the PDF.. The best way will be if ThreatExtraction will bypass PDF with such a signature or wont think this is "evil"

If the signature is considered "active content" then Threat Extraction would definitely remove it. If you can provide a sample document (possibly through the TAC), someone can take a look at it.

After 3 years -have you received any answer form TAC? I have similar problems with signed pdf and active content, like fast save data. "Normal" signed pdfs are ok and unchanged, but signed pdfs with a various active content are sanitized, what is not bad, as long as the signed version is available "long enough" - but "long enough" is being defined individually by each user. So I'm excited to know if you have received any good solution from TAC.
