[jitsi-dev] Big trouble with Master Password after Ubuntu upgrade


#1

Hi there,

after upgrading from Ubuntu 12.04 to 12.10 I have big troubles with
the master password. Jitsi does not accept the master password anymore
and keeps showing pop-ups quite often for the master password. Now I
have to cancel
this and manually add the passwords for the account. I am not able to
recover the master password. I do not see any hint in the log file.
Any Idea?

Cheers,
Matt

Hi,

The problem is most probably a change in java jre. Have you changed from
sun java to openjdk, or some other implementation during the upgrade?
Sun java has some limits on cryptography key length due to US export
restrictions. This limit does not apply to openjdk. Jitsi does not store
the cipher length used to encrypt the passwords, it always uses the
strongest available. So if you change java implementation, you can no
longer decrypt stored passwords.
Good news is that once you re-enter them, you should be fine for a while
again ;-).

Hi Tomas,

thanks for replying. No, did not change the Java.
Though, it could be that the upgrade changed the system
alternatives to openjdk temporarily. But I was before and
after upgrade on Oracle Java 7.

It is not nice but I had to reconfigure all accounts anew as
I was not able to unlock jitsi. No I am running without
master password. Will have to check if re-adding will work
again.

Cheers,
Matt

I know what you mean, it's quite annoying. I had the same problem
sharing jitsi config between windows and linux on dual boot comp. Both
had different java cryptography options, so every time I rebooted, I hit
this issue.
I tried looking into it once or twice, but I was always dragged away by
more urgent things, sorry. And I don't think it's likely I will find
time in any near future :-(.
