HighwayHash
Fast strong hash functions: SipHash/HighwayHash
HighwayHash is a fast, keyed hash function intended for scenarios where you need strong, DoS-resistant hashing without the full overhead of a general-purpose cryptographic hash. It’s designed to defeat hash-flooding attacks by mixing input with wide SIMD operations and a branch-free inner loop, so adversaries can’t cheaply craft many colliding keys. The implementation targets multiple CPU families with vectorized code paths while keeping a portable fallback, yielding high throughput across platforms. ... -

Tiny CUDA Neural Networks
Lightning fast C++/CUDA neural network framework
...Lower-end cards must reduce the n_neurons parameter or use the CutlassMLP (better compatibility but slower) instead. tiny-cuda-nn comes with a PyTorch extension that allows using the fast MLPs and input encodings from within a Python context. These bindings can be significantly faster than full Python implementations; in particular for the multiresolution hash encoding. -

PetoronHash-System
PHASH | post-quantum XOF hashing algorithm | C++20
PHASH is a self-contained, dependency-free, post-quantum XOF hashing algorithm implemented in modern C++20. This release delivers the first fully stable production implementation of the PetoronHash-System — a 1600-bit sponge-based hash function with domain separation, extendable output, and deterministic behavior. Key Features No external dependencies — pure C++20 implementation. Extendable Output (XOF) — supports arbitrary output length (256–8192+ bits). Post-quantum oriented design — ARX-based sponge resistant to Grover-type attacks. Context and salt separation — unique hashing domains for each use-case. ... -

CityHash
Automatically exported from Google code CityHash
CityHash is a family of non-cryptographic hash functions optimized for extremely fast and high-quality hashing of strings on modern CPUs. Developed by Google, it is implemented in C++ and designed to efficiently handle both short and long inputs using techniques such as mixing operations and CPU-specific optimizations. CityHash offers multiple hash sizes—32-bit, 64-bit, 128-bit, and 256-bit variants—with the CRC-based versions leveraging hardware acceleration on CPUs that support SSE4.2 CRC32 instructions. ... -

ftdetector
File type detector library
This project is a tool to detect file types by signatures and mime types. It uses hash tables to make the detection of a file type as fast as possible. The signature and mime types lists are stored at simple user-friendly files. This file type detector supports a lot of formats (image, archive, text, documents, audio, video, fonts and others). It also includes Microsoft OLE compound file types. The detector's algorythm has special features to detect text file types like (HTML, XML, JSON, etc.) and text file UNICODE charsets by using their BOMs (Byte order marks). ... -

ALEPH-w
Data structures and Algorithms library
...It contains the main data structures: single and double lists, special arrays (dynamic and of bits), many types of trees: multitrees, binary search trees, avl, red-black, randomized, treaps, splay and other interesting types. Several types of hash tables are implemented: separated chaining, open adressing with linear probing and double function hash; this last one has a garbage colector mechanism that allows to free deleted entries. Dynamic linear hash tables are implemented too. The main algorithms on graphs are implemented in an easy way and with good performance features. ... -

C++ generic open address hash map
Simple oaht template class
The advantage of this project is that you can use this hash map by including only 2 files to your project. (or 1 if you want by cut/paste pool.hpp content directly in hashmap.hpp if you want). It is template and doesn't require that your contained types are PODs, it doesn't require to set delete_key and empty_key. Unlike google densemap. It is mostly "C++ unordered_map" standard conformant and if you download it, you'll find a visual studio project, or a CMakeLists.txt that integrates the test suite from GCC for unordered_map. ... -

VMDK Forensic Artifact Extractor (VFAE)
C++ application that triages, searches, and extracts files from VMDKs.
...The application allows the user to conduct a quick triage of the Windows directory structure by outputting the results to a specific output file. Additionally, it conducts a pre and post MD5 hash value of the VMDK itself if needed. For specific file searching purposes, it searches for any file type within the off-line VMDK based on a passed in argument via the command-line. Furthermore, you can extract those files that were found in a hard-coded "Extracted Files" directory as well as provide the MD5 hash of each file that was extracted. -
