And, to clarify, do you mean "hack the bitcoin private key" or brute force a password the is locking the wallet? Important distinction.
Well what do you think it is? Of course it's cracking the password. Have you ever heard of anyone cracking a private key? I haven't.
Being a member since 2011 you should understand these noob mistakes and ignore them.
Clearly private keys are impossible (with some exceptions) to crack.
But, many new people are asking about cracking the private key and it is important to know the nature of the question before people waste time answering it.
If you want to ignore the details, feel free, I don't.
