Hash collisions, where the hash function generates the same index for more than one key, therefore typically must be accommodated in some way. In a well-dimensioned hash table, the average...
A good hash function satisfies two basic properties: it should be very fast to compute, and it should minimize duplication of output values (collisions). Hash functions rely on generating...
I want to generate int from a string and be able to generate it back. Something like hash function but two-way function. I want to use ints as ID in my application, but want to be able to convert i...

Hence, we need a way to store these credentials in our database for future comparisons. However, storing passwords on the server side for authentication is a difficult task. Let's explore one of the mechanisms that make password storage secure and easier: hashing. A simple approach to storing passwords is to create a table in our database th ...
Say you have two hashes H(A) and H(B) and you want to combine them. I've read that a good way to combine two hashes is to XOR them, e.g. XOR( H(A), H(B) ). The best explanation I've found is touched
September 2, 2015 · 12:34 PM ET · By Laura Wagner ; Starting Oct. 6, Egg McMuffins, hotcakes, hash browns and more will be available all day at McDonald's. On Tuesday, the company officially approved the decision to offer breakfast items all day at its more than 14,000 U.S. locations, which generally stopped selling the menu items around 10:30 or 11 a.m. The restaurant giant has been testing the all-day breakfast plan at select locations in the U.S. since this spring, and based on the result...
BisetMap is a fast and thread-safe two-way hash map of sets for Rust. - arash16/bisetmap
SHA-256 produces a 256-bit (32-byte) hash value. The SHA (Secure Hash Algorithm) is one of a number of cryptographic hash functions. A cryptographic hash is like a signature for a data set. If you would like to compare two sets of raw data (source of the file, text or similar) it is always better to hash it and compare SHA256 values. It is like the fingerprints of the data. Even if only one symbol is changed the algorithm will produce different hash value. SHA256 algorithm generates an almost-unique, fixed size 256-bit (32-byte) hash. Hash is s ...
