    DSVPN

    DSVPN

    A dead simple VPN

    DSVPN is a Dead Simple VPN, designed to address the most common use case for using a VPN. Runs on TCP. Works pretty much everywhere, including on public WiFi where only TCP/443 is open or reliable. Uses only modern cryptography, with formally verified implementations. Small and constant memory footprint. Doesn't perform any heap memory allocations. Small (~25 KB), with an equally small and readable code base. No external dependencies. Works out of the box. No lousy documentation to read. No configuration file. No post-configuration. Run a single-line command on the server, a similar one on the client and you're done. No firewall and routing rules to manually mess with. Doesn't leak between reconnects if the network doesn't change. Blocks IPv6 on the client to prevent IPv6 leaks. Works on Linux (kernel >= 3.17), macOS and OpenBSD, as well as DragonFly BSD, FreeBSD and NetBSD in client and point-to-point modes. Adding support for other operating systems is trivial.

    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`

    CSVHashCrack Suite

    CSVHashCrack Suite

    Multi hash crack suite

    This script is capable of cracking multiple hashes from a CSV-file like e.g. dumps from sqlmap. Over 17.000 md5-hashes in a CSV-file get cracked with a 14.300.000 lines wordlist in less then 1 min. Lines wich cant get cracked with the wordlist get stored in a .leftToCrack-File to further process with another Wordlist or the bruteforce-tool. In addition to the wordlist-cracker I created also a bruteforce-tool named CSVHashBrutforcer.

    IMPORTANT -- This is an old project that is no longer supported and should not be relied upon for serious applications. If your looking for encryption software, I suggest OpenSSL or GnuPG which are better equipped.

    NDPMon

    NDPMon - Neighbor Discovery Protocol Monitor

    The Neighbor Discovery Protocol Monitor (NDPMon) is used by Internet Protocol version 6 network administrators for monitoring ICMPv6 packets. NDPMon observes the local network for anomalies in the function of nodes using Neighbor Discovery Protocol (NDP) messages, especially during the Stateless Address Autoconfiguration. When an NDP message is flagged, it notifies the administrator by writing to the syslog or by sending an email report. It may also execute a user-defined script. For IPv6, NDPMon is an equivalent of Arpwatch for IPv4, and has similar basic features with added attacks detection. NDPMon also maintains up-to-date a list of neighbors on the link and watches all advertisements and changes. It permits to track the usage of cryptographically generated interface identifiers or temporary global addresses when Privacy extensions are enable (default behavior in Ubuntu and Windows for example).
