Generating a SHA256 Hash from another Hash
#5
Epixoip, thanks for taking the time to answer this question and explain to me why this wouldn't work. I do have a lot of reading to do and I have been doing a lot. I was just curious if it was easy to reverse engineer a hash like this and be able to find the hash that was used to generate it. From the sounds of things this is what the "MDXFIND" you mentioned would be able to do.

I am not trying to be one of those people who design their own password hashing, just trying to understand the flaws in using a system like this. It sounds like if you had an even longer list or a chain of hashes that where all generated from the hash before them that it would be even easier to crack the hashes to find out the has that was used before them to generate it per say. Hopefully that makes sense.
