The Safe C Library provides bound checking memory and string functions per ISO/IEC TR24731. These functions are alternative functions to the existing standard C library that promote safer, more secure programming. The ISO/IEC Programming languages — C spec, C11, now includes the bounded APIs in Appendix K, "Bounds-checking interfaces". This latest upload supports building static library, a shared library and a linux kernel module.

A slightly reduced strength bulk encryption. In exchange for the reduced strength, you get the ability to rsync the encrypted files, so that local changes in the plaintext file will result in (relatively) local changes to the cyphertext file.

Fills a rectangle using given tetris shapes (tetraminos) using an optimized brute force algorithm. A puzzle can have many different solutions; this solver will stop at the first one. Not all puzzles are solveable. Created to solve the annoying tetris puzzles in The Talos Principle and Sigils of Elohim.

antigift could be used for encryption files & folders on USB-flash or HDD partition. Works on Linux (including Android), Windows, Mac OS X, FreeBSD, DragonFly BSD and other on OSes. Do not required installation. Include WIPE tool for wiping free space and tool for recovery forgotten key. See documentation at http://sourceforge.net/p/antigift/wiki/Home/ antigift простой и кросс-платформенный инструмент для шифрования файлов и папок(с ccrypt в качестве основы) Подробности см. на страничке с русской документацией http://sourceforge.net/p/antigift/wiki/rus/

A package of Rijndael, Twofish and Serpent encryption algorithms implemented in x86 assembly. Meant to learn basics of assembly, learn about the algorithms or to be used in a C program.

It moves by itself inside networks like virus infection & plagues, it is being written to solve computer virus problem drastically and responsibly. It is legal, free and open for public domain to improve W3 ICT Security.

Portable, optimised implementation of Bruce Schneier's 64-bit symmetric block cipher, Blowfish. Includes support for ECB, CBC, CFB, OFB and CTR block cipher modes, weak key detection and parallelisation using OpenMP.

Hasher is a .NET class library to help programmers implement standard hashing and checksum algorithms into their own software. Written entirely in C#, Hasher providers a uniform interface to easily use any of the algorithms contained within this library

ExRandom is a small header-only C++11 library for exact sampling from the normal, exponential, and discrete normal distributions (provided that the underlying generator is perfect). This library provides an implementation of the algorithms described in C. F. F. Karney, Sampling exactly from the normal distribution, ACM Trans. Math. Software 42(1), 3:1-14 (Jan. 2016), https://doi.org/10.1145/2710016, https://arxiv.org/abs/1303.6257.

The IEEE 1619 Committee open-source reference implementations of encryption algorithms, plus testing and certification suites, for each encryption algorithm included in the standard.

Java implementation of the most commonly used algorithms for exact string matching, where the pattern is given first.

NAC is a collection of tools for cryptography. The goal is to provide simple-to-use crypto tools (like an OTP, String and number generator, public key algorithm...) you can use under Linux, Windows...

OW.NET -- 1-Wire API port from Java (and J#) to C#. Use the Dallas 1-Wire and iButton chips with standard C# using a serial adapter (also CF.net) or the TMEX drivers on the Windows platform. No J# distribution installation required.

Java module to create, read and write Password Safe V3 encrypted databases. The package is a mature offspring from project JPasswords and can be used with Java 1.8. There is an API document available.

Pambaf is a new encryption algorithm for users or developers with extremely high demands for security.

This project considers the problem of calculating primes as a sorting problem. It includes the most efficient tree-based sorting algorithm that is possible and shows that finding a new prime can be done by sorting the differences between the previous primes in the right way. Unfortunately it has turned out that going this way is even more slowly than trying to find primes by brute force. So it can only be used as a test with heavy load for the sorting algorithm, which can be used for sorting any kind of data. And as already mentioned, it's just the most efficient tree-based sorting algorithm that you can get. But furthermore this way of finding primes interestingly leaves a hard nut to crack for mathematicians: In very rare cases it finds numbers that are not primes. For all primes below one million this phenomenon arises in exactly two cases: 31213 which is 7 * 7 * 7 * 7 * 13 336141 which is 3 * 3 * 13 * 13 * 13 * 17 Who can explain, why?

Raiden block cipher: An extremely lightweight and fast block cipher, developed using genetic programming, with the intention to be an alternative to TEA. This cipher is as fast as TEA, and without many of its known weaknesses.
