How difficult is it to crack .wallet file?

[tyz]

Let's say, someone was able to steal my Multibit .wallet file. How difficult is it to crack it in order to get to the private keys without any information about the password?
Just wondering, because i recently found a virus on my computer and this question came up to me.

Classic or HD? How long is the password?

HD:

Code:

>python btcrecover.py --no-dupchecks --performance --wallet mbhd.wallet.aes
Using 4 worker threads
| 1121  elapsed: 0:00:22  rate:  50.88  P/s
Interrupted after finishing password # 1127

while watching HD video.

Classic:

Code:

>python btcrecover.py --no-dupchecks --performance --wallet multibit_abc123def.key
-snip unrelated warning-
Using 4 worker threads
| 8649934  elapsed: 0:00:20  rate: 430.84 kP/s
Interrupted after finishing password # 8901756

Again while watching HD video. CPU is an i5 4. Gen.

btcrecover does not support GPUs for Multibit yet. AFAIK its also no longer activly developed either.

Classic.

Actually, I do not know the password anymore. I am sure if I have even typed in one when I installed Multibit over a year ago.
I saved all my private keys on a save place, so losing it would not be a big problem for me.

As long as you notice that the file is gone, which might not be the case. Once someone else can access your private keys, they will transfer all coins elsewhere and at that point in time there is nothing you can do.
