Open Source Assembly Cryptography Software for Windows

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

mcrypt, and the accompanying libmcrypt, are intended to be replacements for the old Unix crypt, except that they are under the GPL and support an ever-wider range of algorithms and modes.

Advanced Onion Router is a portable client for the OR network and is intended to be an improved alternative for Tor+Vidalia+Privoxy bundle for Windows users. Some of the improvements include UNICODE paths, support for HTTP and HTTPS proxy protocols on the same Socks4/Socks5 port with HTTP header filtering that generates fake identity-dependent headers every time the identity is changed (proxy chains are also supported), support for NTLM proxies, a User Interface that makes Tor's options and actions more accessible, local banlist for forbidden addresses, private identity isolation, a point-and-click process interceptor that can redirect connections from programs that don't support proxies, also giving them fake information about the local system and support for .onion addresses. Also, it can estimate AS paths for all circuits and prevent AS path intersections, it can restrict circuits to be built using only nodes from different countries, can change circuit lengths and more.

BeeCrypt is an ongoing project to provide a strong and fast cryptography toolkit. Includes entropy sources, random generators, block ciphers, hash functions, message authentication codes, multiprecision integer routines, and public key primitives.

DiskCryptor - fully open solution to encrypt all partitions, including system. The program is a replacement for proprietary DriveCrypt Plus pack and PGP WDE.

Yoda's Protector is a free, open source, Windows 32-bit software protector.

File Crypter is a Simple program, that is able to encrypt your files and decrypt them. A version of File Crypter is included as an example in the xCrypter Library and is called "ncrypter" which is short for "new crypter".

Libecc is an Elliptic Curve Cryptography C++ library for fixed size keys in order to achieve a maximum speed. The goal of this project is to become the first free Open Source library providing the means to generate safe elliptic curves.

Cryptography Tools is a project to develop demonstration tools on classic (currently Caesar and Playfair) & modern crypto-systems, including private & public key encryptions, digital signatures, cryptographic hashes and authenticated encryption.

AVR128DA /Atmega128 microcontroller based open source EID smartcard with RSA (512-2048) and ECC (prime192v1, prime256v1, secp384r1, secp521r1 and secp256k1) support. Compatible with MyEID card from Aventra. Supported in windows and linux by opensc package. Allow about 64KiB space for keys/certificates. PKCS#15 structure supported. USB token with CCID interface based on xmega128a4u with same features as card. High speed AVR multiple precision arithmetic: squaring, multiplication, exponentiation.

The goal of this project is to design and write comercial quality software and aplications with fully respect to free software (like in "free speach"). The software designed by us will target various fields: from scientific applications to multimedia an

Derived from TrueCrypt 6.3 release, I added some command line options to "TrueCrypt Format.exe" to allow TrueCrypt volumes to be created without using the graphical user interface

A package of Rijndael, Twofish and Serpent encryption algorithms implemented in x86 assembly. Meant to learn basics of assembly, learn about the algorithms or to be used in a C program.

This is a simpe Implementation of an The 128-bit AES Encryption Algorithm core in 16-Bit ASM

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.

Optimized implementation of RC4 (Rivest Cipher 4, ARCFOUR) in ASM (x64) for Linux and Windows.

K is a C++ library featuring Genetic Programming, cryptography, 64 bits arithmetic, cross-platform macros and unicode conversion routines. It compiles on NewtonOS, Mac < X, Unix and Windows and it makes little use of C++ templates.

The purpose of this project is to provide a biometric security solution by using voice print, fingerprint and/or facial recognition along with a password and/or smart card support using AES to protect data. Please read forums for if interested.

Powerful 512bit pseudo random encryption, optimized for the x86-64 architecture. Coded in x86-64 assembly language, this has the potential to be one of the most powerful and fastest file encryption engines to date.

GPL hash functions with various ouput sizes.

Swift Crypto is a cross-platform, open-source implementation that mirrors a substantial portion of CryptoKit so server and Linux/Windows ARM64 apps can share one modern crypto API. It exposes high-level, misuse-resistant primitives with Swift ergonomics while delegating to well-vetted backends under the hood. The repository maintains active releases and issue tracking for enhancements like PEM handling and ecosystem compatibility. High-level, misuse-resistant primitives and key handling. SwiftPM distribution for easy inclusion in builds. By matching CryptoKit’s surface, it reduces portability friction between Apple platforms and server environments. The package slots cleanly into SwiftPM builds and is widely adopted across the Swift server ecosystem. Its goal is practical cryptography: safe defaults, clear APIs, and predictable performance.
