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. ...

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. ...

...It allows you to generate MD5 hashes from strings, arrays, ArrayBuffers, and other binary-like data types, making it useful for checksums, fingerprinting, and simple integrity checks on the client or server. The library is exposed as a plain function, so usage is as simple as calling md5(value) and receiving the 32-character hexadecimal hash. It supports multiple packaging formats, including UMD, making it easy to drop into legacy codebases as well as modern bundlers like webpack or Browserify. A comprehensive test suite and demo page are provided to validate behavior across platforms and edge cases.

...It helps you to discover the status of each file in both directories: if it's only in one of them, if it's newer in one than in the other, or if they are simply equal. It also support file content comparison using a hash function, although it's very time consuming. After letting you to choose which files do you want to synchronize, it performs the right operations to make both directories equal (or not, if you want it different). The program can create a backup of the files before overwriting them.

Hash mode interface to the Keccak code package. This program illustrates the use of the Keccak permutation. Usage is much more than a hash function. The NIST compatible settings are subject to change when they publish FIPS PUB 180-5. I wrote this program when evaluating the permutation and developing tree hashing for the Intel(R) MIC architecture.

MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that each ciphertext will differ radically from every other, even on the same message and identical key.

...To achieve long-term data secrecy, Azrar differs from other approaches in terms of not to rely on effective computational deficiencies. It combines a one-time pad with a stream cipher method using the strong cryptographic hash function (family) Skein. Azrar fulfills business requirements for secure data transfer and supports several operating systems natively. It does not use a runtime environment.

MD5-utils is a script for MD5 hash function manipulations. It can crypt one or more word(s) and try to crack one or more hash(es) using online servers.

SubDownloader is an automatic tool to find the subtitles of any video file. It uses a special hash function to identify the videofile and search them into a online server which gives the subtitles.

Provides efficient, effective implementations of 32- and 64-bit hash functions based on Rabin fingerprints / irreducible polynomials, in Java. Also provides integration with java.security.MessageDigest API.
