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.

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.

ShredBitz is a free and simple file shredder tool that can wipe selected files from any hard disk drive. ShredBitz is written in the java programming language and uses a custom written algorithm for shredding. ShredBitz is a very powerful tool.

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.

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

It is a simple password manager for your PC and Smartphone. It works like a text editor and uses a strong cryptography algorithm to generate the end file.

This tool can create one-time-password values based on HOTP (RFC 4226: HOTP: An HMAC-Based One-Time Password Algorithm), TOTP (RFC 6238: TOTP: Time-Based One-Time Password Algorithm) and OCRA (RFC 6287: OCRA: OATH Challenge-Response Algorithm) standards, and also supports client side of OAuth protocols (1.0a, 2.0).

BlowfishVHDL - free fully synthesizable Blowfish encryption algorithm hardware implementation.

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.

This library provides two operations: one to wrap key data, and another to unwrap the key data. This code also includes a fairly comprehensive unit test library which ensures the implementation is verified against the vectors provided in RFC 3394.

I needed a library of functions that enabled me to perform hash functions and symmetric cryptography. I chose MD5 initially but eventually chose SHA as the hashing algorithm due to concerns regarding the \'collision resistance\' of MD5 due to weakne

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.

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.

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.

Starting as a personal study project, I have decided to share this security project. For now, it is a JAVA program that can be used to encrypt and decrypt simple file content (ie files), possibly later evolving into a utility with user interface and/or a library
