SHA256 Hashing

SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. SHA256 hashing is a method to convert arbitrary data into a fixed-size sequence of characters, which typically represents a checksum or fingerprint of the original data. For example, the string Hello, World! becomes dffd6021bb2bd5b0af676290809ec3a53191dd81c7f70a4b28688a362182986f .
