AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.

Cryptomator is a free and open source project that offers multi-platform, transparent client side encryption of your files in the cloud. It works with just about any cloud storage service; is totally transparent so you can work with your files how you normally would; and secure with a 256-bit key length AES encryption. It’s also simple and easy to use with no need for different accounts, key management, cloud access grants or cipher configurations.

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

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.

SSLScan queries SSL services, such as HTTPS, in order to determine the ciphers that are supported. SSLScan is designed to be easy, lean and fast. The output includes prefered ciphers of the SSL service, the certificate and is in Text and XML formats.

StrongKey CryptoCabinet (SKCC) 2.0 is a FIDO-enabled (fidoalliance.org) web application built using Regulatory Compliant Cloud Computing (RC3) architecture (http://bit.ly/rc3infoq). It encrypts files/objects of any type or size, and stores the ciphertext either to public/private clouds—AWS, Azure, Eucalyptus—or local/network drives, while keeping cryptographic keys safe and secure OUTSIDE the cloud. CryptoCabinet leverages the StrongKey CryptoEngine (SKCE)—another FOSS on this site—to perform FIDO U2F strong authentication, encryption/decryption, digital signatures, and cloud integration. CryptoCabinet is a powerful example showcasing StrongKey CryptoEngine's innovative capabilities. Until you modify the CryptoEngine configuration, the default download uses a DEMO Tellaro KeyAppliance (KA) instance to store cryptographic keys. As such, use this ONLY FOR DEMO purposes. Contact us for any of your production needs. Thanks for stopping by!

This project aims at full implementation of RFC4306 and associated RFCs. It is implemented as daemon process, as is custom for this type of software for Unix-like operating systems. Main target for daemon is Linux environment, specifically Fedora Core 5.

RSA Public Key Crypotgraphy for Web Browsers. Use JavaScript to RSA-encrypt data that can only be decrypted on the server, and not by prying eyes. The poor man's SSL...

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.

HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate patches We also support Ubuntu packages. Add them to your package manager with `sudo add-apt-repository ppa:rapier1/hpnssh` Fedora RPMs can be added with, `sudo dnf copr enable rapier1/hpnssh`

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.
