WebDec 11, 2024 · 2. A hash function is a function taking an arbitrary length string as the input, and output a fixed length string. All hash functions are deterministic (correct me if I am wrong). Generally, a good hash function should map the inputs to its output range as uniformly as possible. Cryptographic hash functions have more requirements for security. A hash function takes a key as an input, which is associated with a datum or record and used to identify it to the data storage and retrieval application. The keys may be fixed length, like an integer, or variable length, like a name. In some cases, the key is the datum itself. The output is a hash code used … See more A hash function is any function that can be used to map data of arbitrary size to fixed-size values, though there are some hash functions that support variable length output.

WebFeb 18, 2024 · A hash function takes an arbitrary-length input (a file, a message, a video, etc.) and produces a fixed-length output (for example 256 bits for SHA-256). Hashing the same input produces the same digest or hash. The input of this function can be of any size. It can even be empty. Webof hash tables [Knu], Bloom fllters and their many variants [BM2], summary algorithms for data streams [Mut], and many others.
