Description Alex Thurgood 2012-12-12 11:11:55 UTC
Version (Build ID: 217ba33cb02c86ea25bf62748e1bcbdd1218795)

The title says it all. Steps to reproduce :

1) Create a new Writer document. Type some text. Save the file.
2) File > Digital Signatures brings up the Digital Signature management dialog.
3) If no signatures are already present/listed, there is no way to add new digital certificates/signatures, or even to manage the existing ones.

So, how is this done ?
The only possibility I have found is via Tools > Options > Security

and then it only looks for NSS security certificates, i.e. in Firefox and Thunderbird profiles. Where have the other certificate support protocols gone ? Is there some kind of special build option I need to add in ?

Hello Alex, *,
I can confirm this bug with LO Version (Build ID: 0eaa50a932c8f2199a615e1eb30f7ac74279539) under Debian Testing AMD64 (and it was a problem with 4.0.2 as well ... :( ). I have tried to add my certificates, which I have imported from FF, but to no avail ... :(

I tried to add my already installed certificate, but writer doesn't display it in certificates list.

Bug 82200 added to See Also list. Seems closely related, if not an actual duplicate.

It works for writer in

Steps followed (with certutil tool installed, package libnss3-tools in debian stretch):

1. Create a new certificate database using a password file
$ echo 123 > /tmp/user-certs.pass
$ mkdir /tmp/user-certs
$ certutil -N -f /tmp/user-certs.pass -d /tmp/user-certs

2. Create and add a certificate to the database
$ certutil -S -s "CN=My Issuer" -n myissuer -x -t "C,C,C" -f /tmp/user-certs.pass -d /tmp/user-certs

3. Add the database to libreoffice following steps described by Alex:
a. Go to Tools > Options > Security > "Certificate ..." button in "Certificate Path".
b. Add the path /tmp/user-certs
c. Restart writer

4. Sign the file
a. Open the file to sign
b. Go to File > Digital Signatures > "Sign document..." button
c. Use the previous password (123) to open the added certificate database and add the certificate.

@Juan : your description doesn't indicate how this should work on OSX, where I encounter the same problem. The point is, the dialog offers no way to add a certificate. This is, after all, supposed to be the digital signature management dialog (otherwise, why have an entry for it ?).
Comment 7 Markus Wernig 2017-01-30 09:48:43 UTC
The dialog under "File->Digital Signatures" is not for adding certificates to the certificate store. It is only for signing a document with existing certificates. The dialog to select the signing certificate comes after you hit "Sign Document".

You select the  certificate store to use under "Tools->Options>LibreOffice->Security->Certificate Path" (under Linux this is either from an existing thunderbird/firefox installation or a newly created one).

The type of certificate store available is OS-dependent, so it may differ on Windows and Mac.
Comment 8 Samuel Mehrbrodt (CIB) 2017-06-27 08:09:48 UTC
There is now a "Start certificate manager" button in this dialog which starts an external certificate manager, if available.

I guess this is fixed then. LO is no certificate manager, it only uses existing certificates.
