Is there any way to force a mount when receiving a checksum mismatch: expected 1504336836, got 1627605868 [SSL_Cipher.cpp:541] error? After a reboot the system will not mount. Absolutely no idea what caused the corruption.

The full output of encfs -v is:

Looks like the password is incorrect, there's no fixing that:

Thank you for the reply. The password was part of the issue. My password contains a ';' semi-colon.
So now if I type in the password at a prompt the it does mount.
In case it matters ENCFS6_CONFIG is set.

$ encfs -v -o nonempty /home/jack/Dropbox/.enc /home/jack/Dropbox-
now produces

$ mount
produces

$ encfsctl showcruft /home/jack/Dropbox/.enc
Still produces the same output

However, ls -la Dropbox- produces

total 12

drwxrwxrwx 84 jack users 4096 Aug 12 11:27 ..

So where are the 9 entries?

To what did you set ENCFS6_CONFIG ?
You have a .encfs6.xml file in /home/jack/Dropbox/.enc so you should point to it (or unset ENCFS6_CONFIG).

If the new conf file is a whole new one (not just a password update from the old conf file), and if your data files were created with the old conf file, you won't be able to decode them with the new encfs6.xml file, even if you used same password for both.
You will then have to use the old encfs6.xml file.

Perhaps you are also facing #343.
You would then have to update to EncFS 1.9.2.

@jakoch5876 If this is correct

Version 6 configuration; created by EncFS 1.7.4 (revision 20100713)

it is unlikely that you are affected by #343, confirmed by the fact that you already have 0 and 1 for the booleans.

Can you post the whole encfs6.xml, minus the <encodedKeyData> block?

benrubson commented Aug 22, 2017

Could you please give us the result of the following command ?
ls -l /home/jack/Dropbox/.enc/
ls -lR /home/jack/Dropbox/.dropbox.cache/
(remove the non-encfs content of the second command if you prefer to)

Then, try to copy the .enc folder locally, and mount it.
For example :

cp -a /home/jack/Dropbox/.enc/ /tmp/
mkdir /tmp/local_encfs
export ENCFS6_CONFIG=<your_working_.encfs6.xml_config_file>
encfs /tmp/.enc /tmp/local_encfs
ls -lR /tmp/local_encfs

This could tell us whether or not Dropbox makes EncFS behave badly.

Thx 👍

Mmmmh the copy test may not work if DropBox copies files from its cache...
We'll see, perhaps we'll need to do another test deleting the DropBox cache.

OK thx.
"Unfortunately" your DropBox cache is empty.
Did you always access this EncFS from this computer only, or did it arrive you reached it from 2 or more computers at the same time ?
But as you decode no filename at all, the issue is certainly somewhere else...

Two computers have access the EncFS.
I typical sync the second machine (laptop) before a trip.
They are almost never are accessed at the same time. Meaning I do not make changes to the EncFS on both machines when both are online.

Did you try to access it from the other machine these days to see if ever it could work ?

Unfortunately the exact same situation.

For sure you also tested to show hidden files ls -laR /home/jack/Dropbox/.dropbox.cache/ ?
Does /home/jack/Dropbox/.enc/.encfs6.xml uses the same password than the file ENCFS6_CONFIG points to ? (perhaps one day you missed to set ENCFS6_CONFIG and did not point to the correct conf file).
I have no more idea, perhaps @rfjakob will :)

@rfjakob @vgough your thoughts ?
Appart from an alternate config file / key used to encode the filenames, I don't see...
Thx 👍

Ok I have read this top to bottom again.

You have two computers that sync encrypted files via Dropbox. The encfs config file is NOT synced via Dropbox.

Now both computers cannot decrypt the encrypted files. The question is, how can this problem spread from one computer to the other? There must be some detail missing here.

@jakoch5876 are you sure you did not mess-up your encfs config file bringing it between your 2 computers ?

Could we close this ?
Not sure we can do something more unfortunately :-/
Did you arrive to a conclusion @jakoch5876 ?
