WitrynaSHA-256 returns a 256-bits value while MD5 is only 128-bits, and SHA-256 is slower than MD5, so overall SHA-256 is a bit better than MD5. While using it for something else than a hash function, it doesn’t really matter if it’s a bit slower, so SHA-256 is a better idea, even if it’s not perfect. Pat. Witryna512 than it is to compute a SHA-256 over a given size of data. We propose a standard way to use SHA-512 and truncate its output to 256 bits. For 64 bit architectures, this would yield a more efficient 256 bit hashing algorithm, than the current SHA-256. We call this method SHA-512/256. We also provide a method for reducing the dark and darker with dx11
