The goal is to find the original password, but you’re finding the hash. Finding the hash doesn’t help you in the slightest with finding a password that hashes to that.

Put another way: here, I’ll tell you the hash: DF50B84AFEE438987ECE1542A4D1BCAB4079215EF38C3C3CBB2F4A122886DF27. Now tell me the password. You have 0% chance of succeeding in your lifetime, to at least a dozen decimal places.

It all depends on how complex the password is.

For an 8 char password, it would take a few min.

For a 10 char alphanumeric password, several months on a single GPU

For a 12 char alphanumeric password, Half a century on a single GPU, less if you are willing to throw money at it.

The time would be significantly reduced if the password was vulnerable to a dictionary attack
