Hello,
First off I am a complete noob at all of this and know very little about SHA256 Hash and have been trying to read up and learn what I can about it. I have read that SHA256 Hash are very hard to crack and was curious if it would be a good idea to generate a hash from a hash. Since it would be just as random and it would be 64 char that would have to be figured out seems like it would be unbreakable to me. Or am I mistaking? Would generating a hash from another hash be easy to crack since you knew which char the first hash generated? Hopefully this makes sense.
Example of what I am talking about.
Starting Hash

Then using the above hash to generate this hash.

Then using the above hash to generate this hash.

Is this a strong way to protect your hashes or easily reverse since you know which characters are being used to produce the following hash?
