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)).

Entropy based locality sensitive hashing - Semantic Scholar

WebDec 22, 2024 · Hashing aims to learn short binary codes for compact storage and efficient semantic retrieval. We propose an unsupervised deep hashing layer called Bi-half Net that maximizes entropy of the binary codes. Entropy is maximal when both possible values of the bit are uniformly (half-half) distributed. To maximize bit entropy, we do not add a … WebOct 2, 2013 · This mixing property spreads the entropy from the input evenly through the output. If the input has more bits of entropy than the size of the output, the output will be highly random. This is how highly entropic random numbers are derived from the entropy pool. The hash function used by the Linux kernel is the standard SHA-1 cryptographic …
