Top 16 hash-function Open-Source Projects

• xxHash

  28 8,500 8.3 C

  Extremely fast non-cryptographic hash algorithm

Project mention: The One Billion Row Challenge in CUDA: from 17 minutes to 17 seconds | news.ycombinator.com | 2024-04-13

> GPU Hash Table?

How bad would performance have suffered if you sha256'd the lines to build the map? I'm going to guess "badly"?

Maybe something like this in CUDA: https://github.com/Cyan4973/xxHash ?

• smhasher

  30 1,695 7.1 C++

  Hash function quality and speed tests (by rurban)

Project mention: GxHash - A new (extremely) fast and robust hashing algorithm 🚀 | /r/rust | 2023-11-19

The algorithm passes all SMHasher quality tests and uses rounds of AES block cipher internally, so it is quite robust! For comparison XxH3, t1ha0 and many others don't pass SMHasher (while being slower).

• InfluxDB

  www.influxdata.com featured

• meow_hash

  13 1,684 0.0 C++

  Official version of the Meow hash, an extremely fast level 1 hash

• swift-crypto

  8 1,405 7.0 C

  Open-source implementation of a substantial portion of the API of Apple CryptoKit suitable for use on Linux platforms.

  

Project mention: Swift for Android: How to use Swift-Crypto with Android Studio | dev.to | 2023-11-14

dependencies: [ .package(url: "https://github.com/scade-platform/swift-java.git", branch: "main"), .package(url: "https://github.com/apple/swift-crypto.git", .branch("main")) ]

• multihash

  9 876 3.3 Shell

  Self describing hashes - for future proofing

  

Project mention: Reasons to Prefer Blake3 over Sha256 | news.ycombinator.com | 2023-11-13

Since you seem to have done a fair bit of research in this area, do you have any opinions or thoughts about the Multihash format?

https://multiformats.io/multihash/

It fills in some of the blanks in your "prefixing the hash with the value of the enum for the hash" step.

• highwayhash

  2 857 2.7 Go

  Native Go version of HighwayHash with optimized assembly implementations on Intel and ARM. Able to process over 10 GB/sec on a single core on Intel CPUs - https://en.wikipedia.org/wiki/HighwayHash (by minio)

  

Project mention: Can I concatenate multiple non-crypto hash functions to reduce collision? | /r/golang | 2023-05-16

highwayhash (alt) provides 256 bits. Fast mainly for larger inputs and supports seeds.
