Webb11 feb. 2024 · Hashing the empty string gives undefined behaviour, because inputLen is then zero, and % 0 is undefined. That's a serious bug. digest [i] > 0 On systems where char is an unsigned type, this may be true much more often than on those where it's signed - that looks like a bug. WebbHashing is the process of transforming any given key or a string of characters into another value. This is usually represented by a shorter, fixed-length value or key that represents and makes it easier to find or employ the original string. The most popular use for hashing is the implementation of hash tables.
