php_mt_seed finds possible seeds given the very first PHP mt_rand() output after possible seeding with mt_srand(). With advanced invocation modes, php_mt_seed is also able to match multiple, non-first, and/or inexact mt_rand() outputs to possible seed values. php_mt_seed is written in C with optional SIMD intrinsics (SSE4.1/AVX, XOP, AVX2, MIC) and OpenMP. On a modern quad-core CPU, it is able to search the full 32-bit seed space in one minute (or in just seven seconds on Xeon Phi).

Bletchley is a real-world cryptanalysis framework. It was created to assist with the detection, analysis, and exploitation of cryptographic flaws and aims to help automate the tedious aspects of this analysis while leaving the security expert in control of the process. It features automated token encoding detection (36 encoding variants), passive ciphertext block length and repetition analysis, a script generator for efficient automation of HTTP requests, and a flexible, multithreaded padding oracle attack library with CBC-R support.

SaluSafe is an encrypted email, chat, and file storage and sharing system. Your email and files are highly encrypted end-to-end, and cannot be intercepted by any third party. It was built from the ground up for security via strong cryptography, and is not just another security wrapper on top of an existing email solution.

libbadger is an alternative to existing decentralized authentication systems which require regular direct communication between client and authority. Badger allows clients to authenticate with servers easily and securely in a browserless environment because there is no necessity to tunnel the client to an authority for the purposes of its own authentication. Using Badger, clients only need to communicate with an authority once in their lifetimes.

Shasplit takes a large data block, splits it into smaller parts, and puts those parts into an SHA-based content-addressed store. Reassembling those parts is a trivial "cat" invocation. Repeating parts (e.g., from previous split operations) are stored only once, which allows efficient incremental backups of whole LVM snapshots via Rsync. Shasplit shows its strengths on encrypted block devices, but might be useful for non-encrypted data, too.
