WinSCP is a popular free file manager for Windows supporting SFTP, FTP, FTPS, SCP, S3, WebDAV and local-to-local file transfers. A powerful tool to enhance your productivity with a user-friendly interface and automation options like .NET assembly or batch file scripting. Use WinSCP also for file editing, directory synchronization and site management. WinSCP is open-source and well documented. It is available in English and many other languages.

EJBCA is an enterprise class PKI Certificate Authority built on JEE technology. It is a robust, high performance, platform independent, flexible, and component based CA to be used standalone or integrated in other JEE applications.

DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html

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.

Hide In Picture is a program that allows you to conceal files inside bitmap pictures, using a password. The pictures look like normal images, so people will not suspect there is hidden data in them.

Duply is a shell front end for the duplicity backup tool https://duplicity.us . It simplifies the usage by implementing backup job profiles, batch commands and more. Secure backup to non-trusted file spaces made easy.

A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

axTLS is a TLSv1 SSL library designed specifically for embedded devices, with a highly configurable interface for small memory footprints.

Calypso is a file sharing client using the anonymous network MUTE. Developped using C++ and Qt. For windows and linux, portable to other environments.

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).

SSHDOS is a DOS port of SSH, SCP, SFTP and Telnet clients. Needs a packet driver (or a PPP driver for dialup connection) only. There are two separate packages for SSH1 and for SSH2.

Open-Hashtool is an easy2use Qt based application, which can be used to calculate the hash (MD4; MD5; SHA-1; SHA-224; SHA-256; SHA-384; SHA-512; SHA3-224; SHA3-256; SHA3-386; SHA3-512) of texts and files. It's compatible with Windows and Linux. But Linux users need Qt5.1 or Wine (configuration: Windows Version <= Windows 2008) to run the Open-Hashtool. Please read the Wiki for compiling instructions.

PKS is an OpenPGP Public Key Server. It allows users to store and lookup public keys from the server's database. It can also synchronize with other servers. (This product includes software developed by Marc Horowitz.)

Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the encryption key and part of the data — and multiple equal-sized public chunks, each renamed to its SHA-512 hash and given a uniform timestamp to prevent metadata inference. A private filename conversion table preserves the concatenation order needed for restoration. Together these measures guarantee confidentiality, integrity, and availability regardless of storage provider trustworthiness. Threshold Key Sharing extends this further by splitting the private key, eliminating the single point of failure.

openSNMP is a multi-threaded SNMPv3 engine. This project supports the Simple Network Management Protocol version 3. In particular, it is designed to match the architecture of the Internet Engineering Task Force SNMPv3 standard (RFCs 3410-15).

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.

Protect and Obfuscate Encode PHP File From reading ( Opensource ) Ampare PHP Encoder is a simple and easy to use PHP File Encoder which prevent newbies from reading it automatically. However , Advance and Intermediate able to find way to decode it. FAQ My script doesn't run or terminate Reference : http://php.net/manual/en/function.eval.php When Eval() function run an error code it will automatically terminate so the script doesn't run. Use it only 100% clean code. Please use PHP-Protect Script for better security too . by php protect it first and encode with our software so it second layer protection http://www.phpprotect.info/ I take my free time doing support. So please don't angry or rush me. Donate us : https://www.juthawong.com/donate

This script is capable of cracking multiple hashes from a CSV-file like e.g. dumps from sqlmap. Over 17.000 md5-hashes in a CSV-file get cracked with a 14.300.000 lines wordlist in less then 1 min. Lines wich cant get cracked with the wordlist get stored in a .leftToCrack-File to further process with another Wordlist or the bruteforce-tool. In addition to the wordlist-cracker I created also a bruteforce-tool named CSVHashBrutforcer.
