Hi :slight_smile:
I think the intention at this point is just to get rid of the password protection and open the file, or at least the data in the file.  Protecting it again is for another day!

I attended last week a seminar on the the legal situation with social networks. The presenting US lawyer mentioned that even in the US asking for FB passwords is illegal.

yes, it's due to the privacy laws.

Dennis,
When I am reading your long and excellent explanation, I wonder again how some PW removing tools, which offer a demo with opening the file or showing the PW removed, can claim that the file could be open within a few seconds to a minute?

It has not stopped people from asking in a job interview. In most US
states it is no explicitly illegal nor is it explicitly illegal in US
Federal law. A couple of counter arguments would be: "Do you really want
me to violate my contract with Facebook?", or "Do you realize you are
asking me to violate one the most basic tenets of computer security;
never reveal your log in credentials to anyone?" The first implies that
they will ask you to potentially violate a contract or, worse, the law.
The second implies they are stupid and are very cavalier about
protecting corporate assets.

Under US labor law asking the question potentially allows the employer
to find out information that they can not legally ask in an interview.
This is the primary legal challenge to the question that is an implicit
illegal question by the employer.

I can truthfully say I do not know my Facebook or virtually any other
password because I use a password manager to generate and store them.
And I am not in the habit of carrying the file and the manager around on
a USB stick.

If you're talking about files with protections, minutes is on the long side. It is trivial to remove protections.

If you're talking about Libre Office files created by Save As ... | Save with Password options, I would like to know who is claiming they can do that in any reasonable time.

There are some older forms of Microsoft Word save with password that are easy to crack. Not newer ones though.

Although I have concerns about the quality of the encryption used in ODF documents (what Save As ... | Save with Password uses), I don't think you're going to find any commodity software that is able to crack those in any feasible time period.

If there is, that needs to be widely known.

Care to share any links?

I vaguely remember that there were some versions of MS Office that encrypted using methods that where trivial to crack (ie, minutes). Perhaps it is related to that.

Great ways out of troubles! Thanks.

I meant xls files in MS EXCEL 2003 when I wrote about the short times needed to open them. I protected them against opening.

I never tested a LO file so far - hope I never have to!!!
Here are some links I checked, however I don't recall what was the result for each link. Most of the links I deleted. I just searched for "password remove excel"

For the sake of safety, hopefully these are merely fancy advertising
schemes :wink:

       BUT judging by the number of hackers able to steal data in recent
years, these programs may be working ;-(

       To be conned or not to be conned by these criminal types, seems to
boil down to using common sense -
           something folks once acquired and used; today common sense seems
to have died ;-(

Dennis,

Yet an employer has the right to hire those employees he feels will
fit into his company, benefiting him, his company and its bottom line.

       IF someone acts like a fool, as placing lewd photos of himself or
using abusive and/or blasphemous language on line, then that employer
should have the right to exclude that interviewer from consideration into
his company.

       In fact, I can name quite a few people who have shut their companies
down because federal regulations got too hectic - and many will be shutting
their doors by next year, if the socialists continue to prosper in DC
instead of restoring the US to that which our forefathers' foresaw.
       Europe is falling into the hands of these non-thinking ones who must
think that money grows on trees rather than stemming from the hard work of
the industrious ones; remember Chicken Little.

I have seen many lists of the most common passwords such as password, abc123, qwerty, and the like. Plus many reuse their passwords on several sites so a hacker gets several sites at once.

Googling on "open office password crack" turns up dozens of things.

Here's one that looks real, if outdated:
http://www.theregister.co.uk/2007/04/20/openoffice_password_crack/

That's 2007; we can hope O-O have improved the system since then
Anyone know?

The best-known purveyors of commercial password cracking services
are Elcomsoft. PDFs, Word Documents, ...

This Elcomsoft presentation on Adobe e-book passwords
http://www.cs.cmu.edu/~dst/Adobe/Gallery/ds-defcon/sld001.htm
got their employee Dimitri Skylarov arrested, and led to much
controversy. Eventually, charges were dropped.

Turns out they have one for O-O.

anne-ology,
This is not the first time you show your ignorance about the real world in Europe. Your laws let the USA look like a story by George Orwell. Apparently you also have no idea what the word socialist means and repeats only the indoctrination by your ultra-right wing media garbage.
Please abstain from these useless slanderous remarks,

Old documents generated by Word2000 (*.doc) are well converted to odf 1.2.
However when viewing those *.odt in page view an switching back to

Hi :slight_smile:
Have you tried renaming your User Profile yet?

That usually fixes that sort of problem and loads of other weird things that shouldn't happen.
