any book or doc recommendations on sha256?
we’d be somewhere else entirely without it
Discussion
Technically neither a book or doc, but still a decent explanation.
Oof. I’m not home rn. But I have some bookmarks on all of SHA I’ll send you. It’s still an enigma to me.
Also still don’t know why Bitcoin is specifically SHA-256. I mean I could imagine why it wasn’t SHA-1 but I’m unsure why it wasn’t a different digest of SHA-2. Specifically SHA-512 or SHA-384?
Was SHA-256 enough and we didn’t need SHA-512 or SHA-384? If so, what was wrong with SHA-224?
I don’t know if I’ll ever fully understand SHA or CHF. But it’s cool as shit.
pls share when you can :)
Don't know what you are looking for. The history or technical details. If the later I really like `Serious Cryptography: A Practical Introduction to Modern Encryption` breakdown of the SHA-2 family of digests.
Of all things computer science, the one-way function/digest/hash is my favorite.
