There are several common algorithms for hashing integers. The method giving the best distribution is data-dependent. One of the simplest and most common methods in practice is the modulo division method. If the data to be hashed is small enough, one can use the data itself (reinterpreted as an integer) as the hashed value. The cost of computing this identity hash function is effectively zero. This ha… WebFeb 13, 2014 · An int is a 32-bit value, while a normal MD5 hash is a 128-bit value. Thus there is no representation in one of the integer data types in C#. ulong has the largest domain with 64 bits. The only "native" data type which transports 128 bits is a Guid. But a Guid has a different, semantic meaning. So a MD5 hash consists of 128 bits, which are … WebDec 17, 2024 · 2. Yes, the output of SHA-256 is well distributed over the entire output of the hash function. That also means that any number generated by unknown input is well distributed, of course.
