Password Safe is a password database utility. Users can keep their passwords securely encrypted on their computers. A single Safe Combination unlocks them all.

VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format.

Password Tech is a powerful password generator capable of generating large amounts of cryptographically-secure passwords, pronounceable passwords, pattern-based passwords, passphrases composed of words, and scripted passwords. Passwords can be stored in encrypted databases along with user names, URLs, notes, etc. Password Tech provides lots of options to customize passwords to the users' various needs, and individual scripting with Lua gives full control over the process of password generation. Text encryption is also supported.

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

FreeArc combines best 7-zip and RAR features: auto-selected LZMA/PPMD/Multimedia compression, 1gb dictionary, exe/dict/delta data filters, updatable solid archives, SFXes, recovery record, AES+Twofish+Serpent encryption, Linux support and much more...

EncFSMP can create, mount and edit EncFS (encrypted file system) folders on Windows and Mac OS X.

X Certificate and Key management is an interface for managing asymetric keys like RSA or DSA. It is intended as a small CA for creation and signing certificates. It uses the OpenSSL library for the cryptographic operations. Please see the XCA homepage http://hohnstaedt.de/xca

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.

PuTTY SSH client for Symbian OS

The database access library for C++ programmers that provides the illusion of embedding SQL in regular C++ code, staying entirely within the C++ standard.

FileVerifier++ is a Windows utility for calculating hashes using a number of algorithms including CRC32, MD5, SHA-1, SHA-256/224/384/512, WHIRLPOOL, and RIPEMD-128/160/256/320. Supported hash file formats include MD5SUM .MD5, SFV, BSD CKSUM, and others.

[[We are in the progress of moving to github]] Metalinks is a project to facilitate data distribution over mirrors and P2P networks. It does so by defining an XML format and the tools to handle these. The metalink files contain all the information needed to download and verify files.

Rcracki_mt can be used to perform a rainbow table attack on password hashes. It is intended for indexed&perfected rainbow tables, mainly generated by the distributed project www.freerainbowtables.com

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.

Store your most valuable notes in a LockNote. Hide your everyday notes in a safe place. Application and document in one: the mechanism to encrypt and decrypt a note is part of it. Secure, simple, independent. No installation required.

Whisper is for keeping your private communications private. Whisper is designed to be easy to use (no PKI). Also Whispers can be written on paper if you have to. You don't need your correspondent to generate a key before you can Whisper.

WinMD5sum is a MD5sum tool for those who need a small and simple tool to just get the sum.It has a GUI look and keeps small(only 40KB).Runs only on Windows platform.The highlight is it can handle very large file(over TB) and the speed is fast enough.Enjoy it!

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.

Qtum is a decentralized blockchain project built on Bitcoin's UTXO model, with support for Ethereum Virtual Machine-based smart contracts, and secured by a proof of stake consensus model. It achieves this through the revolutionary Account Abstraction Layer which allows the EVM to communicate with Qtum's Bitcoin-like UTXO blockchain. Welcome to the Qtum Ignition Main Network. This is the main network where the tokens hold value and should be guarded very carefully. If you are testing the network or developing unstable software on Qtum, we highly recommend using either testnet or regtest mode. A Proof of Stake consensus system which is optimized for Qtum's contract model. Any user can stake and help to secure the network. There is no voting, master nodes, or minimum amount required. There have been transactions as small as 2 Qtum that have created blocks in the past. Staking from smart contracts is under development.

Allow the use of ALL smart cards (including EID or DoD smart card) to logon on Windows Vista & later on stand alone computer. This solution doesn't need an Active Directory. Please look at the projet homepage to see a list of smart cards tested.

[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.
