QPass is easy to use, open source password manager application with built-in password generator. You can store in it's database such data as passwords and logins which will be encrypted using AES-256 with PBKDF2(number of iterations set by user). Each entry can include additional information about entry such as name, url adress and description.

TinyCrypt is a simple secure program for encrypting files. The core encryption code is only 76 lines of C code, based on the well known ARC4-D(768) algorithm.

HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format

CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm

Le logiciel NTK Ultra-Compression répond à une problématique essentielle de l’ère numérique : comment réduire la taille des données à leur minimum absolu sans compromis sur leur intégrité, tout en s’affranchissant des contraintes temporelles ? Dans un monde où les volumes de données explosent et où les solutions actuelles de compression restent limitées par des compromis entre rapidité, efficacité et complexité, nous proposons une approche disruptive. Les solutions actuelles, telles que le format ZIP ou 7z, bien qu’efficaces, atteignent leurs limites en termes de taux de compression et d’efficacité pour les fichiers volumineux ou complexes. Ces outils sont souvent contraints par des compromis entre rapidité d’exécution et efficacité de stockage. Cette approche disruptive s’adresse notamment aux utilisateurs ayant besoin de manipuler des fichiers volumineux, comme les logiciels, les jeux vidéo ou les bases de données, où chaque octet économisé compte.

BlowfishVHDL - free fully synthesizable Blowfish encryption algorithm hardware implementation.

TXTCOD encodes and decodes any type of file with a modular algorithm named SAC.

OhCrypt lets you easily encrypt and decrypt files using some of the most popular algorithms, like AES, Blowfish and Serpent. With OhCrypt, you can secure your data with a password-based encryption algorithm through a clean and simple interface. It demonstrates state of the art of cryptology techniques, such as password hashing and salt. Ohcrypt also features self-extractable and self-destructive encrypted files

AresCode2008 is system to crypt files. System is used new cryptography algorithm.

ClearPass (formerly BlowPass) is web based password storage system that uses the Blowfish algorithm and a Host-Proof design pattern.

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.

A very powerful and secure encryption supporting multilevel algorithm hierarchy encryption(bit level),supports infinite length keys and equation creation utility(secondary key) for the utmost security.Support for multiple algorithms.All OS support(ja

DrCrypt, based on basic xor(exclusive or) encryption which is designed to be fast and reliable. Also DrCrypt supports 3 platform.(Java, .NET, Win32)

Enfomi is a cross-platform standalone password-based encryption/decryption program that supports 27 algorithm variants (including AES 256bit). Archives can be self-decrypting, thus making it perfect for mobile applications.

A Javascript implementation of the Blowfish Encryption Algorithm described by Bruce Shneier circa 1993. Blowfish is a keyed, symmetric block cipher common in cipher suites and was placed, by Mr. Shneier, in the public domain.

Use of Michael Rabin's Information Dispersal Algorithm to provide secure, dispersed storage in a networked environment. For full download, please get both Math-FastGF2 and Crypt-IDA releases under the files link. See project wiki for more information.

This tool can create one-time-password values based on HOTP (RFC 4226: HOTP: An HMAC-Based One-Time Password Algorithm), TOTP (RFC 6238: TOTP: Time-Based One-Time Password Algorithm) and OCRA (RFC 6287: OCRA: OATH Challenge-Response Algorithm) standards, and also supports client side of OAuth protocols (1.0a, 2.0).

HTTPBrute is used to calculate HTTP Digest Access Authentication as per RFC 2617. The tool will be able to perform brute force attacks to retrieve a lost password for a given Authentication response. MD5 is the only hashing algorithm implemented.

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

ImpraStorage provided a private imap access to store large files. Each file stored on the server is split in severals random parts. Each part also contains random noise data (lenght depends on a crypt key) to ensure privacy and exclude easy merge without the corresponding key. An index of files stored is encrypt (with the symmetric-key algorithm Kirmah) and regularly updated. Once decrypt, it permit to perform search on the server and download each part. transfert process is transparent. Just vizualize locally the index of stored files and simply select files to download or upload. ImpraStorage automatically launch the parts to download, then merge parts in the appropriate way to rebuild the original file. Inversely, a file to upload is split (in several parts with addition of noise data), and ImpraStorage randomly upload each parts then update the index.

Java Chaotic Random Number Generator - Inspired by chaos theory, the intent of this generator is to produce unseeded, unpredictable numbers. The numbers will not follow a predictable sequence and will not rely on a pseudorandom algorithm.

Java Randomness Test Suite is a gui application to run randomness tests on random stream resource (file or algorithm). Application can be run in command line. Includes general statistical tests, NIST and DIEHARD tests.

The Mav.Crypt tool will be upgraded to many different encryption methods. At the Moment, the only method is ROT13, but we are developing some other technics and a new Algorithm. More Infos shortly at the Project Web Page.

MicroZip is a powerful file compression and encryption utility for mobile phones which allows you to create and extract compressed archives in multiple formats and encrypt sensitive information with powerful AES-256 encryption. MicroZip can create and extract ZIP,TAR,TGZ,TBZ2 archives and extract many other formats as JAR,GZ,BZ2,TBZ,WAR,BZIP2,GZIP,Z,TAZ,CBZ etc. MicroZip allows you to extract selected files without extracting the whole ZIP archive. MicroZip also supports encrypted ZIP archives with both classic ZIP encryption and AES 256 encryption algorithm.

It is a simple password manager for your PC and Smartphone. It works like a text editor and uses a strong cryptography algorithm to generate the end file.
