Still, it is probably very easy to change it so that it use proper, parametrized passwords guess, and have some form of UI. If no one else look into this, I might give it a go. (for this stub to work, you need a running instance of libreoffice started with the command line "$ soffice.exe -accept=socket,host=0,port=2002;urp;") It is 100% possible to integrate this better, in a way that would automatically launch an invisible instance of LibreOffice. In fact the first SDK sample does this, but as I run a 64-bit version of Java, I had to go this way.

In 2001, four or five firms, worldwide, offered commercial OOo password recovery services. One of the firms frankly admitted that they used brute force. The setup fee paid for the computers used for the "attack". The monthly fee covered the utility bills that the "attack" generated. FWIW, this firm now appears to be out of business.

For reference, old .doc where simply flagged as "password protected", which of course got us OpenOffice/LibreOffice simply opening them without warning ;) On the other hand, open password for .odt (and other open document formats) always implied some form of encryption. Granted, previous versions might have used what is now weak encryption, but still it is not something that can be opened easily without password, especially if the file is manipulated on a regular basis, as recent versions of LibreOffice might simply have overwritten the old encryption with something more up to date. I'm afraid that beside brute-force (using a dedicated program) or an unencrypted backup there is no much hope. -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
Re: [libreoffice-users] Lost Pass Word
Hi :) It's worth trying to open the documents in some other office suite or program. If the documents are old enough than you might be able to open them in Microsoft Office. I've only done it the other way around though. An MS Office document opened in LibreOffice just by double-clicking it, and later i found the document had supposedly been password-protected (but not encrypted).

There is a reason for encrypting a document: to prevent others from seeing it if they do not know the password. LibreOffice does an excellent job of this. Most likely you will not be able to open these documents. The only hope you have is have used a simple password that has a significant value in your life and you go through what these are trying them as passwords. Otherwise, it would take access to a super computer running for a few hours to break the password. (This is expensive.)

Re: [libreoffice-users] LO Basic: problem retrieving document Keywords property
Hi John It seems that Keywords is stored as a string array, so if you want to read it into a string you need to convert it into a string. One way to do this is to use the Join-function. In your case exchange the line that crashes with. pDates = Join(oDoc.DocumentProperties.Keywords, ", ") I'm not 100 % sure if comma is used as a separator in all languages, let us know if the code above does not work for you. Regards, Niklas Johansson john herron skrev den 2014-11-26 07:55: For billing purposes I store parameters into the Description fields of LO text document properties. Have no problems retrieving data entered in the Title, Subject, Description property fields by simply assigning the data to string variables. However, when I try to assign to a string variable the contents of the Keywords property, I get the error message depicted in the following code screenshot: http://tinypic.com/m/imus2c/4 Can anyone help me figure out what the problem might be?
