Length of Time to Brute Force? - drew5494 - Mar 8, 2015
Hello just wondering how long it would take to brute force my encrypted HD knowing the password is 12 characters and also knowing it is made up of a word followed by a number and a word again.
The key was picked with Apples Password Helper under Memorable.
Key Examples:
sneak57]bask
Laura90(irks
maul6&Dothan
HBO19_Astrid
Its encrypted with Filevault which uses XTS AES 128.
Any other solutions that you guys can recommend would be very helpful.
Thank you.

It would take millions and millions of years unless you got super super lucky and managed to nail the "word(randomx3)word" system. That's the best vector for key guessing and still boils down to years and years.

Years is fine with me.
So do you have any idea how I can retrieve the hash at all from the HD even if it doesn't help its still worth trying.
Im bringing the HD to a hacker tomorrow who can apparently "hack into banks" according to my friend. Hopefully he can do something.

Not to really burst your bubble here, but I highly doubt he will be able to retrieve the hash. I have found 0 documentation on where the hash and key information is stored. I would be careful with letting anyone tamper with the drive without do a complete disk image backup.

Do you by any chance know how I can backup the disk image?
Thanks.

I want to pick "Yes surely it can be cracked" because it can.
It will only take a hell of a long time I would think haha

There are PLENTY of services for that. That's a huge thing among data recovery companies. They may not be able to decrypt the data, but I'd be willing to bet all of them can clone your disk onto a second drive perfectly. I'm pretty sure even BestBuy offers(or used to offer) this service.

Mm ok thanks ;) Remember that software called passware I mentioned a while back. They have a disk decryption service you can send them an encrypted dapple DMG and they will do their best to decrypt it.
Maybe if I can find a way to extract it I have a slim chance.
