A lightweight and easy-to-use password manager
KeePass Password Safe is a free, open source, lightweight, and easy-to-use password manager for Windows, Linux and Mac OS X, with ports for Android, iPhone/iPad and other mobile devices. With so many passwords to remember and the need to vary passwords to protect your valuable data, it’s nice to have KeePass to manage your passwords in a secure way. KeePass puts all your passwords in a highly encrypted database and locks them with one master key or a key file. As a result, you only have to remember one single master password or select the key file to unlock the whole database. And the databases are encrypted using the best and most secure encryption algorithms currently known, AES and Twofish. See our features page for details.

Browser for using Tor on Windows, Mac OS X or Linux
Tor Browser enables you to use Tor on Windows, Mac OS X, or Linux without needing to install any software. Tor is a software that bounces your communications around a distributed network of relays run by volunteers. This effectively prevents anyone watching your Internet connection from learning what sites you visit; it prevents the sites you visit from learning your physical location; and allows you access to sites which are blocked. Tor Browser can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained (portable).

Open source disk encryption with strong security for the Paranoid
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=0x54DDD393, 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. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

An encryption tool for creating file archives
CrococryptFile is a file encryption tool which creates encrypted archives of arbitrary files and folders. The encryption features of CrococryptFile can be compared to a ZIP utility that uses ZIP's AES encryption. However, there are significant differences. CrococryptFile... - encrypts all file and folder information including filenames, time/date and filesize information, - disguises any information of the archive's content, because all data and meta-data is simply integrated into a giant file dump. =Crypto Suites= For a full list of and details about supported crypto suites, please visit the CrococryptFile Homepage. Examples: - Password-based encryption (following PBKDF2) with AES-256, Twofish, Serpent, ... - Public key encryption using GPG/OpenPGP, Windows Keystore/CAPI with RSA/X.509 certificates - Cloaked (headerless) Password-based Encryption (AES-Twofish-256 cascaded) - ...
