Matthew GarrettIt's been the sort of day where I discover that I have a surprisingly useful ability to intuit fields in headers that are probably uuids and figure out what this structure is as a result
Did you know that you can impress people by just pasting some bytes into github search and then saying "Ah yes that's an EFI-spec RSA2048-SHA256 signature" (you do not need to do the github bit in front of them)
Anyway simply mechanically copying potentially interesting looking sequences of bytes into search engines is an incredibly underrated part of reverse engineering work
Matt Palmer@mjg59 which works until the stochastic parrots take over. I enjoy asking ChatGPT the SHA256 hash of various strings. Never the same answer twice.

Sorry for the confusion. The reason you may be getting a different answer every time is because the hashing algorithm uses a different random "seed". This is to prevent what's known as a "hash collision", a generally undesirable event that breaks one of the promises of hashing, that every input produces a unique output. I hope this clarifies why you'd get a different hash for the same string.
