Cool. Yeah, there is nothing there. But I got a little further:
I ran this command:

openssl enc -d -p -aes-256-cbc -a -in Quark-wallet-keys-09-11-17 -out privatekeys.txt -pass pass:*********

and then I got values for:

SALT:XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
KEY:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
IV:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
plus a whole lot of error messages and shit


but then when I try to load the importprivkey into the qt-client I get

Invalid private key encoding (code -5)

Hello. I also got into Quark in 2013 and am very excited about all these recent developments. I have my quarks in the android wallet and I have hit a wall trying to export the private key(s), so I can import it into v10.4.5. I haven't seen a guide thus far.

So here's where I stand: I saved my wallet with a simple password, moved it to a Linux computer and ran the command:
/usr/bin/sudo /usr/bin/openssl enc -d -aes-256-cbc -a -in Quark-wallet-keys-XX-XX-XX -out wallet.txt -k password;

I get some response about
iv undefined

Also any other general information. How long is the key, 58 or 62 characters? What letter does it start with? etc.
Thanks so much in advance, I am so ridiculously happy about quark's prospects!
