I am using libreoffice on Windows 7. When I want to create a digital signature (File > Digital Signatures > Digital Signatures...) or (File > Export As > Export As PDF), I cannot see my certificate. When I click "Start Certificate Manager..." in the "Digital Signtures" dialog, I get an error "could not find any certificate manager."

My certificate is in Thunderbird 45.4 and Firefox 49 and work. Googling provides me with references to Tools > Options > Security > Certificate Path, but that does not exist (any more?) In the expert settings (Tools > Options > Libre Office > Advanced, click Open Expert Configuration), I find an entry called org.openoffice.Office.Common / Security / Scripting, property CertDir, type void. I assume this is the missing cert-path entry. When I click Edit, nothing happens.

I am effectively unable to digitally sign with libreoffice. Where can I find a "Certificate Manager" for my Windows machine?

I am not familiar with using certificates, but just a guess: on Windows, LibreOffice uses system certificates, not some application certificates (and Mozilla products like Thunderbird and Firefox may use some own certificate management system).

Mike, what a good guess, wonderful, it now works! I had only imported the certificate into FF and TB on that machine, and the docs don't seem to mention the Windows cert store, a pity. Still I wonder why the "Start Certificate Manager does not work, the onboard tool in Windows 7 is even called certmgr.exe. Thanks for this!

Try Tools>Options>Security>TSAS which is for Time Stamped export to PDF and see if that does what you want.

No, that is a different thing. Timestamping would in fact only work if I could sign in the first place, with my own certificate.
