Cryptographic hash function in ruby

WebFeb 27, 2024 · The cryptographic function siphash currently used in MRI is pretty a new function and it is not time-tested yet as older functions. Although it is not documented, Ruby function hash should be the same as hash function used inside the hash tables and its value should be always the same for an object during one MRI run. WebAn algorithm that computes a numerical value (called the hash value) on a data file or electronic message that is used to represent that file or message, and depends on the entire contents of the file or message. A hash function can be considered to be a fingerprint of the file or message. See Hash function.
