Hash compression
WebApr 21, 2024 · A hash is a function that converts one value to another. Hashing data is a common practice in computer science and is used for several different purposes. Examples include cryptography, compression, checksum generation, and data indexing. Hashing is a natural fit for cryptography because it masks the original data with another value. WebJun 24, 2024 · 1. Actually, you don't need a SAT solver; the SHA-256 hash compression function is h c ( s t a t e, m e s s a g e) = s t a t e ⊕ E m e s s a g e ( s t a t e), for an easily invertible (if you know the message) E. All you need to do is take your arbitrary message block and find the state for which 0 = E m e s s a g e ( s t a t e) – poncho.
