I've got a computer generated sha256 hash of which I need the original value. I know the value is a random 64 character string of alphanumerical, lower and uppercase, numbers and underscores + dots.

Would it be possible in a reasonable amount of time to bruteforce this?

Answer 1

There are 64 possibilities in 64 positions giving a total or 64 to the power of 64 combinations which is 3.9402006196394479212279040100143613805079739270 × 10^115 So no. Even if you had every computer on earth working on it for 1,000,000 years you still wouldn't be close
