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. WebAug 26, 2016 · A cryptographic hash function is a hash function which takes an input (or 'message') and returns a fixed-size alphanumeric string, which is called the hash value (sometimes called a message digest, a digital fingerprint, a digest or a checksum). The most known of them are functions like MD5, SHA1 and SHA2.
