git-annex allows managing files with git, without checking the file contents into git. While that may seem paradoxical, it is useful when dealing with files larger than git can currently easily handle, whether due to limitations in memory, checksumming time, or disk space.
This is a simple program written in Java that tries to find a hash by using a dictionary file. It can be as good as the dictionary used in it. The dictionary file is not included. If you have better ideias for this code, just let me now :) DISCLAIMER: This tool is for educational purposes only. ... [More]
A PHP security library. * Session handler * XSS filter * CSRF protection * Password hashing * Encrypting data * Random data generator * Yubikey - one time tokens * One time passwords
AshTL aims to provide a complete framework for dealing with spatial data in an efficient, parallel manner. As such, we primarily provide container classes and data types relating to 2D and 3D coordinate grids. AshTL is currently in alpha development (some features may not work correctly, and ... [More]
An extremely memory-efficient hash_map implementation. 2 bits/entry overhead! The SparseHash library contains several hash-map implementations, including implementations that optimize for space or speed. These hashtable implementations are similar in API to SGI's hash_map class and the tr1 ... [More]
A tool for Linux systems, to store cryptographic hashes of files in posix extended attributes, and compare them against remote databases, to check for duplicate files across several machines.
pHash is an open source software library released under the GPLv3 license that implements several perceptual hashing algorithms, and provides a C-like API to use those functions in your own programs. pHash itself is written in C++. Potential applications include copyright protection, similarity ... [More]
Libhashish is a powerful and generic hash library for C and C++. The library attempt to combine the best algorithms in this area and take all kinds of optimizations into account. Furthermore the main focus is applicability - at least you should use this library.
phpass is a portable password hashing framework for use in PHP applications. The preferred (most secure) hashing method supported by phpass is the OpenBSD-style bcrypt (known in PHP as CRYPT_BLOWFISH), with a fallback to BSDI-style extended DES-based hashes (known in PHP as CRYPT_EXT_DES), and a ...
