DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on...

JMixNet is a Java implementation of a so called Chauminian Mixnet (or mix-net, or even mix net, at your will ;). It is an anonymous communication network, designed to provide anonymity in data transfers among Internet users.

A multi-platform tool to convert RSA private keys between SFM format (modulus, public exponent, private exponent) and CRT format, in both ways.

AUM is an extremely fast, small-state, cryptographically secure pseudo-random number generator and stream cipher. AUM exhibits uniform distribution, mixes rapidly, has no detected bias, and comes in three variants: AUM16, with an internal state array of 16+4 32-bit words; AUM32, with an internal state of 32+4 words; and AUM64 with a 64+4-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

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...

MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only...

BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a...

Composed of a Java steganographic library and GUI to use steganography. Primarily intended for research communities on security and steganography to implement new dissimulation and steganalysis algorithms. More information at www.hidereveal.org

FroZenLight connects simple line art and mathematics. The source of light can be positioned so that either symmetric reflection patterns or secret messages (Cryptography) are created. Example light patterns and math exercises for education are provided.

Perso can handle different types of identity card numbers (e.g. German/Austrian ID-card and passport). It can check the numbers for correctness. Also it can extract information from the numbers (e.g. birthday) or generate numbers using custum values.

CryptDS is cross platform file encryption software with AES-128 encryption based on Open Source library Crypt++. CryptDS has a wxWidgets GUI interface.

Want to create your own CA? Have a pain typing openssl command? With Certificate Utilities, we include many functions like create private key. This is the most professional and free certificate toolkit based on openssl and lisenced under under GPL!

This project aims at porting visual cryptography, which only works with transparent slides, to ordinary 80g/m^2 white paper. Please read the documentation before using the program.
