WebA reasonable hash rate on a good computer might be 1GH/s (billion hashes per second) - it'll be at least within a couple orders of magnitude of that from the very best hasher to the very worst. 2^256 is the number of hashes you might have to do, and you can do a billion a second, 2^256/10^9 = 1.16*10^68 seconds. When a user creates an account on a website, they are typically asked to create a password. Rather than storing the password in plain text, which would make it vulnerable to theft in the event of a data breach, the website will typically use a cryptographic hash function to generate a unique hash of the password.
