Hash function that produces short hashes? - Stack Overflow
WebNov 8, 2013 · A typical password only has a few dozen bits of entropy, and running a password through a hash function does not add any entropy to it. Therefore, such keys are easily attacked using a dictionary or brute force. The most commonly accepted solution is to make the hash function very slow. Algorithms designed for this are called "password … WebJul 21, 2016 · Hash nevers increases entropy. But considering the full sha256 possible values, you actually would loose entropy because of collisions. Some of the 256 bit values will have collisions, that is, for 256bit input to sha1 and md5 there will be x1 and x2 that sha1(sha256(x1)) == sha1(sha256(x2)) and md5(sha256(y1)) == md5(sha256(y2)).

WebApr 23, 2024 · If you have a 10 characters hash you get higher entropy if it is encoded with base64 vs base16 (or hex). How higher? With base16 you get 4 bits of information per character, with base64 this figure is 6bits/char. Totaly a 10 char "hex" hash will have 40bits of entropy while a base64 60bits. WebAug 27, 2013 · With a good hash function, the unpredictability of any part of the hash is proportional to the part's size. If you want, you can encode it base 32 instead of the standard hex base 16.
