Open Source C Decryption Software

The AWS Encryption SDK for C is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It uses a data format compatible with the AWS Encryption SDKs in other languages. For more information on the AWS Encryption SDKs in all languages, see the Developer Guide. We will demonstrate some simple build recipes for Linux, Mac, and Windows operating systems. These recipes assume a newly installed system with default installs of dependency packages. The Windows instructions install everything in your current directory (where you run the build process). The AWS Encryption SDK for C can be used with AWS KMS, but it is not required. For best results when doing a build with AWS KMS integration, do not install aws-c-common directly. Build and install the AWS SDK for C++, which will build and install aws-c-common for you (see the C++ SDK dependencies here).

ProxyCrypt is a command line tool that creates encrypted volumes within a file or a hard drive. Encryption and decryption are made on the fly, allowing you to use encrypted volumes like normal ones. Designed for paranoids and advanced users, it is also fast, very lightweight, open source and easy to recompile. See the features below. It works as a "proxy" for the AIM driver or the ImDisk driver. AIM driver is included in the full package. See the documentation for more informations and an example of use: https://sourceforge.net/p/proxycrypt/doc/ Requirements: - Windows 7 or later - Arsenal Image Mounter or ImDisk Virtual Disk Driver - Administrative privileges - 64-bit CPU with SSE3 instructions - About 1 GB of RAM temporarily required for password checking with default settings Hashes of all versions: https://sourceforge.net/p/proxycrypt/doc/Hash

A ultrafast lightweight (no GUI) encryption/decryption software using the CryptoAPI on Windows platform, to secure just about anything - regular files and directories, consoles, communication resources(COM ports), Disk devices, pipes and sockets anythin

Ncrypt is intended to give you security in an insecure environment. If you are wanting to encrypt files, wishing to hide your activites from prying eyes, and want to "cover your tracks", Ncrypt is for you.

Encrypts and decrypts files using XOR operation.

This a a small program to encrypt/decrypt files using AES (Advanced Encryption Standard)

This project is dedicated to creating encryption programs, along with their decryption counterparts. The encryptor will encrypt any file (that I've tested) and decrypt a file.

DavUtils is a collection of easy to use WebDAV client tools. The built-in client-side encryption allows you to encrypt and decrypt files on the fly with AES. Currently two command line tools are available: dav is a multipurpose WebDAV client that can be used like the standard unix tools ls, mkdir and rm. The other tool is dav-sync that can synchronize local files with a WebDAV server. It is very flexible and configurable and has advanced data safety features to prevent data loss. The integrated client-side AES encryption makes it secure to use public clouds.

The BP-Tools set consist from applications supporting EFT testing, benchmarking and transaction service development. BP-Tools suite currently consists of following three components: - BP-CCALC: Cryptographic Calculator - BP-CardEdit: Thales P3 Input/Output file editor - BP-EMVT: EMV Tool - BP-HCMD: Thales HSM Commander

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.

Cryptic is a cryptographic applications suite for encryption/decryption of data, calculating cryptographic hashes or message digests and securing user passwords using a master password in a password safe.

Decrypt utility for files encrypted by FileError_22001 virus (also known as Trojan.Encoder.33).

Fast Encryptor is a quick-and-dirty en/decryptor that can operate on files and/or streams. Coded for SPEED as opposed to security.

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.

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.

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

Little program that uses the bit XOR operation for encryptioning and decryptioning, for now, just text files.

An almost complete one-time-pad suite. Has many features which are non-existant in other OTP programs, and includes 5 programs (plus an uninstaller) which allow the user to create keys, create fake keys, encrypt, and decrypt files.

Command line utility for encryption/decryption files, computing message digests

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.

Simple tool for file encryption and folder content encryption with AES 256. Files can also be hashed with a SHA1 signature. A command line version is available as well as a GUI version. One other useful feature is to encrypt messages for emails.

Note: this is alpha-quality software, and isn't ready for production use. STROBE is a lightweight framework for cryptographic protocols. It supports encryption/decryption, hashing, pseudorandom generation and message authentication. It integrates these components in an innovative way that makes secure protocol design relatively simple. With the included elliptic curve code, STROBE additionally supports asymmetric key exchange and digital signature creation and verification.

This is a more secure file encryption program which uses SERPENT cipher and WHIRLPOOL+SHA-256 hash functions in key creation and for integrity checking.

This xxteac program utilizes the "Corrected Block TEA" encryption/decryption algorithm by Roger Needham and David Wheeler. The original algorithm has been slightly modified to allow arbitary length passwords / password files.
