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

Keytool is an Eclipse plugin that maintains keystores and certificates. It allows you to create certificates and put them in a keystore. You can from Eclipse, open and inspect certificates that are stored as .cer, or in a given keystore.

Crypto++ is a free C++ class library of cryptographic schemes originally written by Wei Dai. The library is now maintained by a community of volunteers. The Crypto++ website is located at https://cryptopp.com/, and the source code is located at https://github.com/weidai11/cryptopp. The repository was moved in response to developer requests for Git access. The SourceForge site will remain in "read only" mode for historical purposes. You should visit the Crypto++ website at https://cryptopp.com/ or GitHub at https://github.com/weidai11/cryptopp to view the latest news, download the latest source code, file bugs and request features. We thank SourceForge for hosting us through the years.

PortableSigner is a tool for digital signing (with X.509 certificates) of PDF files

The OpenCA PKI Development Project is a collaborative effort to develop a robust, full-featured and Open Source out-of-the-box Certification Authority implementing the most used protocols with full-strength cryptography world-wide.

[IMPORTANT] Retroshare is now distributed on Github. Please go to http://retroshare.net to find the latest releases and sources. RetroShare is a cross-platform, secured and decentralized communication system. It lets you to securely chat, share photos, videos, and more with family and friends, using OpenPGP to authenticate peers and OpenSSL to encrypt all communication.

encrypt is a multi-platform, file encryption application. Binary packages are currently provided for Arch, Debian, Fedora, MS Windows, Android and OS X. For further details, including the latest source code, visit https://albinoloverats.net/projects/encrypt

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.

This project provides a simple Java-based steganography tool that can hide a message inside a 24-bit colour image so that knowing how it was embedded, or performing statistical analysis, does not make it any easier to find the concealed information.

This is a Hash Calculating tool that calculates MD2,MD5,SHA-1,SHA-256,SHA-384,SHA-512 hash of text or a file. This has GUI developed in java swings.All it needs is sun jre installed.

This project is devoted to provide a simple software layer for digital signature, when an hardware cryptographic token is required. The default implementation tries to comply as strictly as possible with the italian law digital signature directives.

jPBC is a Java porting of the PBC Library, a Pairing-Based Cryptography Library written in C. It supports symmetric and asymmetric pairing. With jPBC it is really easy to use such a strong cryptographic primitive.

UPDATE 2024: Get a new version here: https://github.com/ivoras/EncryptedNotepad2 "Encrypted Notepad" does only one thing, but aims to do it perfectly - a Notepad-like simple text editor where files are saved (and later loaded) encrypted with industrial strength algorithms. Available both for the desktop (as a Java application) and on Android. Unencrypted data is never stored on-disk. Source is released (on SourceForge) under the BSD license.

ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool.

UFONet - Is a set of hacktivist tools that allow launching coordinated DDoS and DoS attacks and combine both in a single offensive. It also works as an encrypted DarkNET to publish and receive content by creating a global client/server network based on a direct-connect P2P architecture. + FAQ: https://ufonet.03c8.net/FAQ.html -------------------------------------------- -> UFONet-v1.8 [DPh] "DarK-PhAnT0m!"

Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array (so-called "seed phrase") using exclusive OR (XOR)/Vernam cipher (a.k.a. One Time Pad). If not input by a user, an encryption key is automatically generated at random. Encryption with such a key preserves integrity of BIP-39 checksums of all keys (that's distinct while also compatible with SeedXOR implementation).

HashTool calculates the most common hash and hmac values of files and strings by using the "Bouncy Castle Java cryptography API".
