This chapter continues “Chapter 2 : Blockchain 1: Numbers and Alphanumeric”. We will discuss ASCII, how to find the hash for ASCII characters, and our general target of Sha256: what is it, how to get sha256 hash from a webpage, and our three functions:.sha256(),.sha256web (),.sha256LocalFile (), and.sha256add(). In addition, we will show you how to play games #3 and #4.
