WebBYVoidA small evaluation of several commonly used string hash functions. The results of the evaluation, according to the score from high to low are BKDRHash, APHash, DJBHash, JSHash, RSHash, SDBMHash, PJWHash, ELFHash. ... Among them, the optimal string hash algorithm BKDRHash function is implemented as follows: // BKDR Hash … WebThese functions use bitwise operations to make each character have an effect on the last function value. There are also hash functions represented by MD5 and SHA1, which are almost impossible to find collisions with.
