A question about 128-bit disk image encryption

Hi everyone. First post here.
A bitter first post actually. My bag was stolen yesterday. An iPad2 and my external usb drive is the casualty.
Anyway, I had some personal folders on the disk (HFS formatted). They were encrypted with Disk Utility in AES128 bit with more than 10 digits all in numbers. I was so down today until I read this post in the forum: (And that let me to join the forum)

People here suggested that it's almost impossible to crack the 128 bit aes encryption. But a lot of time passed by since this thread was active. Any ideas? Do you think my information is safe, wherever they are...
Thanks.

 

Of course I agree. It's just relaxing to know. Only a cold comfort.
