Is there a string that's hash is equal to itself?
For example if you know that all the values are strings with different lengths then a simple string length can be a good hash function. However if your values ...
General Purpose Hash Function Algorithms - By Arash Partow
The perfect hash function by definition states that no collisions will occur meaning no repeating hash values will arise from different elements of the group.
Animator.StringToHash with TCPClient - Unity Discussions
So yes, it should be the same even on different machines. However keep in mind that it is just a hashing function and can have collisions. So in ...
How to implement a hash table (in C) - Ben Hoyt
A hash table is a container data structure that allows you to quickly look up a key (often a string) to find its corresponding value (any data type). Under the ...

What Is the MD5 Hashing Algorithm & How Does It Work? - Avast
SHA outputs a longer string of hexadecimal characters, so you can easily tell the difference between the two types. This is a big reason why SHA ...
Hashes are written as a pair of curly braces {} containing any number of key-value pairs. A key is separated from its value by an arrow.
To test how good the hash function built into the HashMap class is, I wrote a short class that would load a large number of strings (7,000) from a file, and ...
