Open Source C++ Encryption Software

VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

Microsoft SEAL is an open-source homomorphic encryption library that allows computations to be performed directly on encrypted data, with no need for any decryption. Developed by the Cryptography and Privacy Research group at Microsoft, it enables software engineers to build end-to-end encrypted data storage and computation services that never have to procure the customer's key. Microsoft SEAL is very easy to use, compile and run in many different environments. Homomorphic encryption is an encryption scheme that allows the cloud to compute directly on the encrypted data, without requiring the data to be decrypted first. This results in encrypted computations remaining encrypted, decrypted only by the data owner using the secret key.

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.

A simple but powerful cross-platform utility for managing and accessing your most secret data. It stores passwords and whole files, so it can literally store any information you want to keep secret. Access your most-used passwords/URLs right out of a desktop tray icon. For advanced users, it includes a separate utility called Grypto-Transforms, which has a universal hash calculator with all the major hash functions, generic encrypt/decrypt functions and a base64/hex converter. Although the interface is simple and intuitive, the security is top-notch. It uses AES with CCM to secure and authenticate the data.

Vigenère is a program for encrypting and decrypting text using the Vigenère cipher. Built-in cryptanalysis tools make it possible to crack the cipher without needing the key — or even knowing its length.

Command line encryption tool for one time, daemon, or stream data processing. Data stats, check sums, conversion to/from text. Data/keys from files, pipes, standard input. In-place/diverted processing or data-analysis-only. Random, file, password keys.

sectar: a program that creates encrypted tape archives(tar files), using the AES algorithm Rijndael. Encryption exported under exemption TSU 740.13. Was star, now sectar.

NoFault is a library written in C used to encrypt or decrypt data with XOR encryption. KNoFault, NoFault32 and CLNoFault are direct applications of the library, which is easy to use in your own programs.

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.

A Plugin for Pegasus Mail, supporting S/MIME Encryption, Decryption, Signing and Signature verifying. In addition, key management is provided.

Vijner 974 E-Sys (2048 bits and unlimited encryption). Enables easy (un-)encryption from text input or .txt file, and to (un-)encrypt raw files, with Vigenère Algorithm + unlimited encryption keys. Simple and powerful. Adapt to fit your needs.

This software provides an easy graphical way to encrypt your text documents from source code , text files ,scripts even jpeg files .It is a enhanced version of my earlier project https://sourceforge.net/p/xorencrypt which used win32 GUI . This is a demonstration of working of XOR encryption which was used by Germans in World War II (http://en.wikipedia.org/wiki/Lorenz_cipher) . Besides from XOR'ing the message with password after every encryption the key changes pseudorandomly. The password you provide is hashed ( SHA256 ) and saved into the encrypted file to check if the password provided is correct.This algorithm has limitations in general more the numbers of relative characters in the password to plaintext more secure will be the encryption. XOR encrypt has a 3.5 of 5 editors rating from softpedia http://www.softpedia.com/get/Security/Encrypting/XOR-Encrypt.shtml

Cypher is an encryption program that uses the AES (Rijndael) algorithm to encrypt and decrypt files. You can use Cypher to protect sensitive data from unwanted access.

A user-friendly, cross-platform utility for managing and accessing your most secret data. It stores passwords and whole files, so it can literally store any information you want to keep secret. Access your most-used passwords/URLs right out of a desktop tray icon. For advanced users, it includes a separate utility called Grypto-Transforms, which has a universal hash calculator with all the major hash functions, generic encrypt/decrypt functions and a base64/hex converter.
