Open Source C Encryption Software - Page 3

Simple, lightweight, cross-platform (Windows / Linux / ARM6 Linux), cross-arch (x32 / x64), standalone command line file encryption program. GnuPG is probably the best application for cross-platform encryption. However, its usage on Windows PCs may be inconvenient (installation administrator rights; large executable size for perhaps just a one-time file decryption, complicated command-line switches for stronger encryption). NCrypt would fulfill this task, but does not operate on 64-bit Windows - MLCrypt was created because of this. The program's primary aim is cascade encryption: create an encrypted outer layer over an existing compressed and encrypted archive file. (Each encryption layer should have a different complex password.) MLCrypt.zip contains all the executables: Linux, Windows, Raspberry Pi.

CryptoLib is a crypto library for PalmOS based on OpenSSL, which implements BlowFish algorithm, and is intended to support any other crypting algorithm in the future.

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 5 lines of code: Ten arithmetic and bitwise operations in all. It's called MOTE because a PRNG can't be made much smaller (or faster) without introducing bias or severely reducing avalanche. MOTE alternates its shift and rotation constants unpredictably, and has passed the most stringent industry-standard tests for randomness and security, including NIST & DIEHARD.

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.

NCrypted is a simple file encryption software. It is implemented on top of AES 128-bit algorithm. This software was designed to be as simple as possible, so you won't find any fancy, flashy gui elements or complicated advanced options. You can also use it directly from command line. NCrypted can automatically detect and take advantage of your NVidia graphics card to speed up the file processing.

One-time password generator for the Nokia N900. Supports OAUTH tokens (HOTP, TOTP) as well as the Mobile-OTP algorithm.

PalmOS MD5 algorithm Shared Library

A command-line to help encipher and decipher your password based on a simple algorithm. Java version provides GUI.

Pot of Gold is an open source implementation of Philippe Oechslin's "Faster Cryptanalytic Time-Memory Trade-Off" paper. It performs precomputation on a particular hash algorithm which can be later used to reverse certain hashes.

The PowerCiph Data Encryption Algorithm is a versatile, yet simplistic, encryption algorithm/protocol. The ultimate goal of the algorithm is simplicity, compactness, and a lack of prerequisites.

Real-Time Proactive Secret Sharing Library for RTAI is an implementation of the Shamir's secret sharing scheme and Herzberg's proactive secret sharing algorithm. The library uses a port of GNU GMP in order to make multiple precision arithmetic operatio

A simple but fully-featured implementation of the simple Caesar Cipher encryption algorithm, specifically 'rot13' - Caesar with a factor of 13. Supports file and tty input/output, internationalisation, and also includes a shared library.

SES brings back the uncrackable onetime pad, with a digital twist. It is well known that a random key of message-length is the only provably unbreakable cipher. SES uses cryptographic strength pseudo-random keys of message-length for its many encipherments, in addition to offering true one-time pad capability for the intrepid. SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to efficiently cipher text of arbitrary length or files of any size or type. Use it with confidence. To achieve complete one-on-one privacy, SES traverses several levels en route to its output. The more words in your key-phrase, the more layers of encipherment SES applies. It is part Vigenere, part onetime pad, part cryptographic hash, not to mention the essential scrambler element, each component driven by ISAAC, with all key-derivation and stretching relying on Keccak in 512-bit configuration.

Secure Hash Algorithm variant of the nist maintained Secure Hash Algorithm. this is a 1024 bit digest. Comments suggestions always welcome. Rick Removed old downloads as they are long outdated. The update is the last version I worked on. Algorithm is based on the SHA2 digest. I may work on an updated version for c++11

ScatterStorm Mosaic Image Encryptor is not your father's stegonagraphy engine. It's purpose is not to sneak data around in image trojan-horses as much as to be able to reversibly scramble an image (or parts of one) in a mosaic cloud

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 each ciphertext will differ radically from every other, even on the same message and identical key.
