Cryptographic hash functions are hard to compute by hand but easy for a computer to do. You can use this online tool that can calculate the SHA256 value for any string you want. When we discussed cryptographic hash functions, we said they could take any input. This includes nothing. Using the website above, try and calculate the hash value of nothing by not typing anything (directly push the button Calculate) in the Data field.
What are the last 3 digits of the hash value?
