The FNV-1a hash differs from the FNV-1 hash only by the order in which the multiply and XOR is performed: [9] [11] algorithm fnv-1a is hash := FNV_offset_basis for each byte_of_data to be hashed do hash := hash XOR byte_of_data hash := hash × FNV_prime return hash. The above pseudocode has the same assumptions that were noted for the FNV-1 ...
The Fowler–Noll–Vo hash function (FNV) was created by Glenn Fowler and Phong Vo in 1991 with contributions from Landon Curt Noll. FNV with its two variants, FNV-1 and FNV-1a, is very widely used in Linux, FreeBSD OSes, DNS servers, NFS, Twitter, PlayStation 2, and Xbox, among others. lookup3 was created by Robert Jenkins.
Fowler–Noll–Vo hash function (FNV Hash) 32, 64, 128, 256, 512, or 1024 bits xor/product or product/XOR Jenkins hash function: 32 or 64 bits XOR/addition
The following tables compare general and technical information for a number of cryptographic hash functions. See the individual functions' articles for further information. This article is not all-inclusive or necessarily up-to-date. An overview of hash function security/cryptanalysis can be found at hash function security summary.
The FNV parameter table should be extended to include the FNV prime and offset_basis for the 512 and 1024 bit values. I recommend that column labeled "FNV-1 offset base" be called "offset_basis" (or "offset basis") because the same values are used for both FNV-1 and FNV-1a hash functions. chongo 04:27, 27 January 2009 (UTC)
For use in a hash table, the FNV-1a variant is likely the best choice, as it has better (more dispersed) clustering behavior than FNV-1. For some applications, particularly when keys are long, the newer Jenkins lookup3.c hash function may be a better performer.
Kevin O'Connor is joined by Jason Timpf to discuss seven big takeaways from last weekend's NBA action before previewing the NBA Cup.
MurmurHash is a non-cryptographic hash function suitable for general hash-based lookup. [1] [2] [3] It was created by Austin Appleby in 2008 [4] and, as of 8 January 2016, [5] is hosted on GitHub along with its test suite named SMHasher. It also exists in a number of variants, [6] all of which have been released into the public domain. The name ...
