WebJun 1, 2013 · Use the built-in hash () function. This function, at least on the machine I'm developing for (with python 2.7, and a 64-bit cpu) produces an integer that fits within 32 bits - not large enough for my purposes. Use hashlib. hashlib provides cryptographic hash routines, which are far slower than they need to be for non-cryptographic purposes.

WebJan 18, 2013 · Hash function performance is unlikely to be an issue. Even the "slow" hash functions (e.g. SHA-256) will run faster on a typical PC than the harddisk: reading the file will be the bottleneck, not hashing it (a 2.4 GHz PC can hash data with SHA-512 at a speed close to 200 MB/s, using a single core). If hash function performance is an issue, then ... WebSep 10, 2015 · This hash code is based on the object’s address; however, the objects can move in memory when the heap is compacted and must retain their hash codes.

WebJul 12, 2024 · Here is an example of a hash function that has the properties you desire: H (message, outputLength) = 1 << outputLength It is clearly a hash function, since it maps … WebOn other weaker architectures, were hash function performance has some chance to actually matter, these functions are quite slow. There are other constructions which can make a hash function out of a block cipher, e.g. the one used in Skein; but they also tend to require larger blocks than what the AES is defined over. WebEvery cryptographic hash function is a hash function. But not every hash function is a cryptographic hash.
