    DENRIT

    DENRIT

    Perform anonymous and non-anonymous pentesting.

    DENRIT allows remote administration of anonymous networks (TOR, I2P and FreeNet). Also, contains a pentesting module to execute commands using a selected anonymous network, pentesting with TOR or TCP Follows a client/server model with well-defined communication interfaces. SSH is used to allow remote clients to access the machine and manage any anonymous network that is installed there, plus allows penetration testing anonymously (or non-anonymously) using tools such as Metasploit Framework, nmap, nikto, among others. The list of supported applications will grow as the project progresses. Until now, this project is under development and is very unstable (and some features aren't included). But I've been developing constantly and I think that soon this software will become stable and very useful to pentesters, hackers and researchers (I hope so!) Well, you can see the wiki page and the presentation exposed in the download section if you want more information about this project.

    Kypeless

    Kypeless

    Fully decentralised secure p2p communication program

    Kypeless encapsulates strong symmetric and asymmetric cryptography so you can get the benefits of secure communication following some simple steps. Right now, Kypeless is unstable pre-alpha software, published only for testing purposes. Kypeless allows you to exchange instant messages, long not-so-instant messages and files, but a lot more features are planned to be implemented later.
