VirtualBox Disk Image Encryption

[kiara]

I have a VirtualBox image that is encrypted that I have forgotten the password. I created a new test.vbox and found a PHP program - vboxdie-cracker that is able to find the correct password for the test from a wordlist. But it only guesses 2 passwords per second. Here is what the vboxdie-cracker extracts from the test.vbox file with a password of password:

I have a usual pattern of characters I use and I wrote a C++ program to create a word list of several thousand permutations, but no luck so far. I need more speed. Any help on how to use hashcat to crack this would be much appreciated.

My confusion is how to use 2 salts with hashcat?

how did u encrypt the virtual hard drive in the first place?
isnt it LUKS ?
