Open Source Linux Encryption Algorithms

The AWS Encryption SDK 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 enables you to focus on the core functionality of your application, rather than on how to best encrypt and decrypt your data. The AWS Encryption SDK is provided free of charge under the Apache 2.0 license. With the AWS Encryption SDK, you define a master key provider (Java and Python) or a keyring (C, C#/.NET, and JavaScript) that determines which wrapping keys you use to protect your data. Then you encrypt and decrypt your data using straightforward methods provided by the AWS Encryption SDK. The AWS Encryption SDK does the rest. Without the AWS Encryption SDK, you might spend more effort on building an encryption solution than on the core functionality of your application. By default, the AWS Encryption SDK generates a unique data key for each data object that it encrypts.

Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. You can build shadowsocks-libev and all its dependencies by script. The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router. Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user. We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy.

MicroZip is a powerful file compression and encryption utility for mobile phones which allows you to create and extract compressed archives in multiple formats and encrypt sensitive information with powerful AES-256 encryption. MicroZip can create and extract ZIP,TAR,TGZ,TBZ2 archives and extract many other formats as JAR,GZ,BZ2,TBZ,WAR,BZIP2,GZIP,Z,TAZ,CBZ etc. MicroZip allows you to extract selected files without extracting the whole ZIP archive. MicroZip also supports encrypted ZIP archives with both classic ZIP encryption and AES 256 encryption algorithm.

mp3stegz is an application that apply steganographic (steganography) algorithm in mp3 files. mp3stegz will maintain original mp3 file's size and sound quality. The hidden message is compressed(zlib) and encrypted(Rijndael).

haveged is a daemon that feeds entropy into the linux /dev/random pool using a random number generator based upon the HArdware Volatile Entropy Gathering and Expansion algorithm.

BlowfishVHDL - free fully synthesizable Blowfish encryption algorithm hardware implementation.

sha is a file hashing utility that uses the NIST's SHA-1, SHA-256, SHA-384, & SHA-512 hash algorithms. It can be used for file integrity checking, remote file comparisons, etc. The portable algorithm implementations can be useful in other projects too.

ClearPass (formerly BlowPass) is web based password storage system that uses the Blowfish algorithm and a Host-Proof design pattern.

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

Enfomi is a cross-platform standalone password-based encryption/decryption program that supports 27 algorithm variants (including AES 256bit). Archives can be self-decrypting, thus making it perfect for mobile applications.

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.

HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format

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.

Encryption/Decryption demonstration app using the S-DES algorithm. Use the Java runtime environment 11 for execution. The GUI pops up that allows entering a 10-bit encryption/decryption key in binary (0, 1 digits) and the plaintext/ciphertext in the same form (8-bit). Executing the algorithm, decription of the encoding/decoding functionality is provided in the three main text boxes.

A algorithm encryption based on TEA (Tiny encryption Algorithm) that will help the user to encrypt his text files and decrypt whenever the user wants as long as he uses the same key.It is simple to use but doesnt work with really really long text files.Will implement mac and other OS in the future.
