Bug ID: 124768
Summary: Exported PDF digital signature conformance with ETSI
standard
Product: LibreOffice
Version: 6.2.2.2 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Description:
At the moment, documents signed when exporting a PDF from LibreOffice are
almost compliant with the ETSI specification, as reported by the conformance
checker, with a single error reported:
5. Error | Tool | Location-{CodeTest}:SubFilter-{CheckIfValueIsOneOfDefined} |
Found value: 'adbe.pkcs7.detached''. Allowed values: ETSI.CAdES.detached
So to be compliant with ETSI specs, it should use the ETSI tag rather than the
Adobe tag. (Adobe itself supports that as well, see:
https://www.adobe.com/devnet-docs/acrobatetk/tools/DigSigDC/standards.html )
Note that the test fully passes when the "sign existing PDF" option is used,
via Draw, as opposed to the Export to PDF option from Writer.
Steps to Reproduce:
1. Create a document in Writer.
2. Use the Export as PDF... option
3. Select the certificate in the Digital Signature tab
4. Upload the result to the ETSI conformance checker
(https://signatures-conformance-checker.etsi.org/ manual registration needed at
the moment).
5. Check report results.
Actual Results:
Failure with one error, about the algorithm to create the signature hash.
Expected Results:
Pass.
Reproducible: Always
User Profile Reset: No
