GnuPG 2.1.21

GnuPG (the GNU Privacy Guard or GPG) is GNU's tool for secure communication and data storage. It can be used to encrypt data and to create digital signatures. It includes an advanced key management facility and is compliant with the proposed OpenPGP Internet standard as described in RFC2440. As such, it is meant to be compatible with PGP from NAI, Inc. Because it does not use any patented algorithms, it can be used without any restrictions.

Secrets 0.4.0

Secrets can be used to split a secret text into shares to be distributed to friends. When all friends agree, the shares can be combined to retrieve the original secret text, for instance to give consensual access to a lost pin, a password, a list of passwords, a private document or a key to an encrypted volume. Secret sharing can be useful in many different situations and this tool is a simple and well documented free and open source implementation available for anyone to use from this website,

LibreSSL 2.5.4

Image Lock PEA 1.0

Image Lock PEA protects photos, drawings, and documents in image format with a password. Thanks to the integrated viewer the images are never stored unencrypted on the hard disk, but are held only in memory. The Image Lock PEA uses functions to derive the key from the password, that protect also against attackers with a high budget. In addition to the confidentiality, an authenticated encryption protects the integrity and authenticity of the images.

Naamari 1.3.2

Naamari is AES&SHA-based crypto-synchronizer for cloud/remote file storage, with cryptographic and transport modules being separate applications. It works with 4 locations. 1st: local dir with original files. 2nd: dir containing folder structure and names of files placed into storage (but not content). 3rd & 4th - storages: local (another local dir) and remote (say, a cloud). In storages, there are no folders, files have pseudo-random names and encrypted content ("flattening"). The main module

Tomb, the Crypto Undertaker 2.4

Tomb is a system to make strong encryption easy for everyday use. A tomb is like a locked folder that can be safely transported and hidden in a filesystem. Its keys can be kept separate; for example, you can keep the tomb on your computer and its key on a USB stick. Tomb is written in code that is easy to review and links shared components: it consists of a ZShell script and desktop integration apps; it uses standard GNU tools and the crypto API of the Linux kernel (dm-crypt) via cryptsetup.

Notebook PEA 1.0

Notebook PEA protects texts using authenticated encryption (EAX mode) for confidentiality, integrity, and authenticity of the text, using the new key derivation function Catena-Dragonfly. Notebook PEA works like a self-decrypting archive (SDA): the plaintext is never stored on disk, instead it is displayed in a simple text editor with some styling functionality, redo/undo and copy, cut, paste commands.

gpgpwd 0.7.2

gpgpwd is a terminal-based password manager. It stores a list of passwords and their associated usernames in a GnuPG-encrypted file, and allows you to easily retrieve, change, and add to that file as needed. It also generates random passwords which you can use, easily allowing you to have one "master password" (for your gpg key), with one unique and random password for each website or service you use, ensuring that your other accounts stay safe even if one password gets leaked. gpgpwd can als

Mandos 1.7.15

The Mandos system allows computers to have encrypted root file systems and at the same time be capable of remote or unattended reboots. The computers run a small client program in the initial RAM disk environment which will communicate with a server over a network. All network communication is encrypted using TLS. The clients are identified by the server using an OpenPGP key that is unique to each client. The server sends the clients an encrypted password. The encrypted password is decrypted by

libntru 0.5

C implementation of NTRUEncrypt An implementation of the public-key encryption scheme NTRUEncrypt in C. NTRUEncrypt's main strengths are high performance and resistance to quantum computer attacks.

For more information on the NTRUEncrypt algorithm, see the NTRU introduction page at http://tbuktu.github.com/ntru/

Dowse 0.9

Dowse is a transparent proxy facilitating the awareness of ingoing and outgoing connections, from, to, and within a local area network. Dowse provides a central point of soft control for all local traffic: from ARP traffic (layer 2) to TCP/IP (layers 3 and 4) as well as application space, by chaining a firewall setup to a trasparent proxy setup. A core feature for Dowse is that of hiding all the complexity of such a setup.

Jaro Mail 4.2

Jaro Mail is an integrated suite of interoperable tools for GNU/Linux and Apple/OSX to manage e-mail communication in a private and efficient way, without relying too much on on-line services, in fact encouraging users to store e-mail locally. Rather than reinventing the wheel, Jaro Mail reuses some existing free and open source tools working since more than 10 years, generating their configurations and setting up integrations automatically.
