Devonthink Pro Office 2.9 Sync Encryption Key


I’ve setup a couple of sync locations (one local sync store, one sync store) and syncing seems to work fine for both, from what I can see so far, that is as long as I don’t use encryption.

For the sync store I would really like to use encryption though. However, so far I have not been able to make it work. I’ve tried using numerous passwords/keys (in varying length, etc.), but always get the error message “invalid encryption key”.

Would anyone happen to know if there are any specific requirements (e.g. length, capital letters, etc.) when choosing an encryption password/key for syncing in Devonthink Pro Office 2.9? I couldn’t find anything on this in the forum or the user manual.

Thanks & best regards,

Please provide an example of what you’ve tried.

I have tried encryption keys such as these:



I just tested BiCyuF112087 with a account and it works as expected.

If you were part of the beta testing group for Sync, I would quit DEVONthink, and delete the ~/Library/Application Support/DEVONthink Pro 2/Cloudy folder to make sure there’s no legacy data from testing.

After changing the encryption key, please clean the sync store and upload your databases again.

thanks a lot for the help and advise, sincerely appreciate it!

Just to make sure I understand correctly, if I’ve created a sync store on without an encryption key and wish to add one at a later date (after I’ve uploaded all databases) or change a chosen encryption key at a later date, I would have to clean the entire sync store (i.e. delete the databases from the sync store) and (re-)upload all databases again from scratch, correct?

One more question, if I sync two Macs with the same databases in a sync store on, would I have to use the same encryption key on both Macs?

Thanks again for your kind help!

Best regards,

Yes, the key has to be identical.

thank you very much for the prompt reply and clarification!

Kind regards,

just wanted to share that after cleaning the sync store on (running the command on both Macs), assigning the same encryption key on both Macs and (re-)uploading the databases again, everything works fine now.

Thanks a lot for the support!

Kind regards,

No problem.

As a side note: Cleaning only has to be done from from machine as the only one copy of the Sync data is only stored at the Sync location.

Cheers! :smiley:
