How long would it take to crack AES-128 knowing a 12 character length password

encryptionhacking

I have a hard drive which was encrypted with XTS-AES 128-bit on OS X. I know how long the password is but that's it.
How long would it take to decrypt it already knowing this?
I have read that in years to come when quantum computers are available it can be broken.
Dont comment "never" or "6 billion year"
Think outside of the box with advancing technology in years to come.
I have memories on here.

Best Answer

The average 12 character password will take 6 billion years to brute-force at 100,000 passwords per second.

Allowing special characters brings this to around 150 billion years.
