Dad: Son, what does SHA256 hashing do?
Son: Hi Dad,
Let's assume a want to hash this message. The hash would be 64 characters long, always, no matter how long the message is.
The hash is always the same if I hash the same message, and there is no way to get back to the original message based on the hash.
Dad: So, hashing is a one-way transformation of information and the information is not the information itself. The information for me and others is that the given information is "true".
Son: Yes, Dad, you can understand it that way.
