WebApr 13, 2015 · Hash functions always produce a fixed length output regardless of the input (i.e. MD5 >> 128 bits, SHA-256 >> 256 bits), but why? I know that it is how the designer designed them to be, but why they designed the output to have the same length? So that it can be stored in a consistent fashion? easier to be compared? less complicated? … WebThe four hash functions that comprise SHA-2 are SHA-224, SHA-256 (SHA 256 Algorithm), SHA-384, and SHA-512, with the numeric portion of the name indicating the number of bits in the key. SHA-2 functions are more secure than SHA-1 although not as widely used currently. SHA-1 Algorithm
