A good hash function should map the expected inputs as evenly as possible over its output range. That is, every hash value in the output range should be generated with roughly the same probability. The reason for this last requirement is that the cost of hashing-based methods goes up sharply as the number of collisions—pairs of inputs that are mapped to the same hash value—increases. If some hash values are more likely to occur than others, a larger fraction of th… WebJan 3, 2024 · Hash values represent large amounts of data as much smaller numeric values, so they are used with digital signatures.

The MD5 algorithm is a widely used hash function producing a 128-bit hash value (16 Bytes, 32 Hexdecimal characters). The ComputeHash method of the System.Security.Cryptography.MD5 class returns the hash as an array of 16 bytes. Example: pergotex weinor
