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.

Written in C/CUDA, this tool recovers lost mnemonics and passphrases for BTC, ETH, TRX, DOGE, LTC, DASH, ZEC, BCH, and BTG. Supports BIP32/44/49/84 derivation paths. Features partial phrase recovery and a built-in dictionary for fast, efficient results. Compliant with wallet standards.

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 simple working implementation of 64-bit DES encryption/decryption alogrithm in C++. Could act as guide to undestanding the algorithm. Its buggy so help me out :-)

The fcrypt and fdecrypt programs provide a comprehensive symmetric encryption tool kit for encrypting and decrypting files.

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.

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.

It is a fine tool to encrypt your data.It uses a dinamic algorithm and a nice interface.It`s easy to use and helpful.

The Tiny Encryption Algorithm (TEA) was developed by David Wheeler and Roger Needham at the Computer Laboratory of Cambridge University. The variant used was developed by David Wagner. TEACrypt 80x86 is the porting of this algorithm to the 80x86 platform

TextCodec can encode texts using simple algorithm and then decode them by using statistical language data.

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.

DecodeBase64 does exactly what the title says: it decodes strings encoded with the Base64 algorithm. Source code is provided in both Java and C++.

A one key 64-bit encryption program designed for Linux and Windows. There is a console version, and also a GUI version provided by wxWindows.

This simple encryption program, allows you to virtually encrypt all documents and even decrypt them back using the secure XOR encryption algorithm. This program is designed for beginners who know little about encryption.

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.

This release marks the first production-ready publication of 1654, a dependency-free cryptographic vault engine built around a strict vault abstraction and a wide-state cryptographic design. 1654 is not a wrapper around existing crypto libraries. It is a self-contained system whose cryptographic behavior is fully defined within the repository. Key Characteristics Vault-oriented model Encrypted data is treated as a sealed container-safe with explicit operations, not as a password-wrapped file. Dependency-free design The entire cryptographic surface is auditable in-tree. PetoronHash as the cryptographic core All key material derivation, diffusion, and internal transformations are driven by PetoronHash 1024-bit wide internal state The architecture uses a wide internal state to increase diffusion depth and structural safety margins. https://github.com/01alekseev/1654 Petoron | Ivan Alekseev | MIT license
