One-way compression functions are used to construct cryptographic hash functions. They transform two fixed-length inputs into a fixed-length output, and it is difficult to compute inputs that compress to a given output. They are built from block ciphers using methods such as Davies–Meyer, Matyas–Meyer–Oseas, Miyaguchi–Preneel, MDC-2/Meyer–Schilling, MDC-4, Hirose, and 2BOW.
