Yoshimi is a fork of ZynAddSubFX, a feature-heavy real-time software synthesizer. It offers three synthesizer engines, multitimbral and polyphonic synths, microtonal capabilities, custom envelopes, effects, etc. Yoshimi improves on support for JACK features, such as JACK MIDI.

amsynth is an easy-to-use software synthesizer with a classic subtractive synthesizer topology. Its features include: dual oscillators (sine, saw, square, noise) with hard sync; 12 and 24 dB/oct resonant filters (low-pass, high-pass, band-pass, notch); mono, poly, legato keyboard modes; dual ADSR envelope generators for filter and amplitude; LFO which can modulate the oscillators, filter, and amplitude; distortion and reverb effects.

musl is a simple and lightweight C standard library. It strives to be correct in the sense of standards-conformance and safety.

Myrddin is a programming language. It features strong type checking, generics, type inference, closures, and traits. It aims for C like low level control. This combination makes Myrddin suitable for anything ranging from desktop applications, to embedded systems and potentially even kernel development.

Ncdu is a disk usage analyzer with an ncurses interface, aimed to be run on a remote server where you don't have an entire graphical setup, but have to do with a simple SSH connection. ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.

Curses is the interface between Perl and the curses library of your system.

GNU Ncurses is a library which provides capabilities to write text to a terminal in a terminal-independent manner. It supports pads and color as well as multiple highlights and forms characters. It is typically used to implement user interfaces for command-line applications. The accompanying ncursesw library provides wide character support.

STFL is a language for easily describing GUIs. STFL is also the name of this library which translates those descriptions into a curses-based widget set for text terminals.

STFL descriptions do not contain any concrete layouting information, such as x/y coordinates of widgets. Instead, container widgets such as vertical and horizontal boxes, as well as tables, are used to group widgets. The actual layouting work is done by the STFL library. This allows STFL GUIs to handle terminals of different sizes and terminal resize events transparently for the application programmer.

Curses Development Kit (CDK) is a C library of widgets which allow a programmer to quickly create TUI applications. Widgets are objects whose appearance and behavior can be customized, e.g. a pulldown menu or a file-viewer.

Dialog is a script-interpreter and a library which provides a set of curses widgets, such as dialog boxes.

Netpbm is a toolkit for the manipulation of graphic images, including the conversion of images between a variety of different formats. There are over 300 separate tools in the package including converters for about 100 graphics formats.

GNU Nettle is a low-level cryptographic library. It is designed to fit in easily in almost any context. It can be easily included in cryptographic toolkits for object-oriented languages or in applications themselves.

Iodine tunnels IPv4 data through a DNS server. This can be useful in different situations where internet access is firewalled, but DNS queries are allowed. The bandwidth is asymmetrical, with limited upstream and up to 1 Mbit/s downstream.

PuTTY is a graphical text terminal client. It supports SSH, telnet, and raw socket connections with good terminal emulation. It can authenticate with public keys and Kerberos single-sign-on. It also includes command-line SFTP and older SCP implementations.

YAZ is a C/C++ library for information retrieval applications using Z39.50, SRU or Solr Web Service protocols for information retrieval. It also offers ZOOM API implementing them.

sslh is a network protocol demultiplexer. It acts like a switchboard, accepting connections from clients on one port and forwarding them to different servers based on the contents of the first received data packet. Detection of common protocols like HTTP(S), SSL, SSH, OpenVPN, tinc, and XMPP is already implemented, but any other protocol that matches a regular expression can be added. sslh's name comes from its original application of serving both SSH and HTTPS on port 443, allowing SSH connections from inside corporate firewalls that block port 22.

This package provides a modern, but Linux-specific implementation of the traceroute command that can be used to follow the route taken by packets on an IP network on their way to a given host. It utilizes the IP protocol's time to live (TTL) field and attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to the host. Compared to other implementations, this traceroute command allows some traces for unprivileged users.

Nebula is a peer-to-peer networking tool based on the Noise Protocol Framework. It is not a fully decentralized network, but instead uses central discovery nodes and a certificate authority to facilitate direct, encrypted peer-to-peer connections from behind most firewalls and NAT layers.

Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach.

Small tool to capture packets from WLAN devices. After capturing, upload the "uncleaned" cap to https://wpa-sec.stanev.org/?submit to see if the access point or the client is vulnerable to a dictionary attack. Convert the cap file to hccapx format and/or to WPA-PMKID-PBKDF2 hashline (16800) with hcxpcaptool from the hcxtools package and check if the WLAN key or the master key was transmitted unencrypted.
