Open Source C Encryption Software

Small stream encryption program for Unix

Figaro's Password Manager (FPM) is a GNOME application that allows you to securely store & categorize your passwords, which are encrypted using the blowfish algorithm. It can launch applications using the host names, user names, and passwords you supply.

A simple file encrypter written in C/C++. Tested sucessfully with 0.5 GB file. Despite having well-functioning cryptographic features, it may not be reliable. This application is provided with no warranty or guarantees of any kind. Use it at your own risk! Source code is available at: https://github.com/Northstrix/Bootleg-AES-256-CBC-File-Encrypter Made with the help of Perplexity Similar projects: https://sourceforge.net/projects/sta-file-encrypter/ https://sourceforge.net/projects/aes-256-cbc-file-encrypter/

This project will provide a library for using the AES round 3 cipher candidates (Mars, RC6, Rijndael, Serpent, and Twofish) in an easy to use API. Support for MD5, SHA.

Alkindus is an automated solver for short monoalphabetic substitution ciphers without word divisions.

B-Trust eDoc is a program built on top of LibDigiDoc a free implementation of the OpenXAdES standard for signing/encrypting files using smartcard tokens. It also contains Openssl and PKCS11 wrapper classes in C++ which might be useful to developers.

An original bruteforce-based encryption/decryption system. BBE was originally conceived to chat with encrypted text on IRC. mIRC and X-Chat support BBE via script addon. BBE can also encrypt MIME encoded files. Blowfish encryption is currently supported.

Cameloid is a new TCP/UDP based P2P voice and video encryption software, that will provide high level of privacy for all levels of communication using only quality secret-key ciphers to ensure long-term security.

This is an experimental program that encrypt/decrypt/divide/join files. This program uses a new algorithm made by me, this algorithm is experimental and I working on it, every day this algoritm will be better.

This its a simple project of the RSA algorithm. The purpose of this project isn't to develop an impressive program, it's an easy understand of the algorithm and the C programing.

CryptoServer is the daemon for handling Sign-Verify, Encryption-Dencryption, Envelop-Openenvelop based on OpenSSL including the SEED symmetric algorithm (Korean Standard Symmetric Algorithm). It's interface is just tcp/ip socket and very easy to handle

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.

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.

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

Rinecrypt uses the Gladman implentation of the AES algorithm Rijndael and a SHA256 hash among other things, to encrypt/decrypt a file with a user supplied passsword.

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.

Open Source file encryption, written to learn about cryptograpy, programming, etc. And hopefully come up with some new encryption techniques that might benefit the public.

Semeir is a Encryption algorithm, Capable of block encryption. It is written in pure C. It is platform independent, and is promising for Embedded systems. Intended as an alternate, yet secure data encryption cipher.

Application based on asymmetric cryptography (ECC) allows encrypt and decrypt files and generates digital signatures. Currently implemented algorithms include ECDSA and ECIES.

SysK allows to crypt text by using system informations calculate the algorithm. For each user,the crypt algo will be different. It's written in C language for Linux x86. The objective is to allows it to crypt streams, binaries and more.

A program that encrypts multiple files. It uses new encryption algorithms, such as a Three-Block Feistel chiper, ArchFurry's algorithm and a new hash function. Licensed under the ISC.

Cryptar is a cryptographic network backup program that is able to be very efficient with network resources by using an algorithm derived from the rsync algorithm. It uses SHA-1 hashes to verify (sign) its data and AES to encrypt it.

Encrypt-roller is a encryption/decryption package. The goal of the project is to incorporate multiple encryption schemes and mechanisms to provide security and validity for files being stored or transferred.
