whois searches for an object in a WHOIS (RFC 3912) database. It is commonly used to look up the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system. It can automatically select the appropriate server for most queries.

For historical reasons, this package also includes mkpasswd, which encrypts passwords using crypt(3) and is unrelated to the Expect command of the same name.

Binwalk is a tool for analyzing, reverse engineering, and extracting firmware images.

Rizin is a reverse engineering framework and a set of small command-line utilities, providing a complete binary analysis experience with features like disassembler, hexadecimal editor, emulation, binary inspection, debugger, and more.

Lynis is a security auditing tool. It performs an in-depth security scan and runs on the system itself. The primary goal is to test security defenses and provide tips for further system hardening. It will also scan for general system information, vulnerable software packages, and possible configuration issues.

fping is a ping-like program which uses ICMP echo requests to determine if a target host is responding.

fping differs from ping in that you can specify any number of targets on the command line, or specify a file containing the lists of targets to ping. Instead of sending to one target until it times out or replies, fping will send out a ping packet and move on to the next target in a round-robin fashion.

Nmap ("Network Mapper") is a network discovery and security auditing tool. It is also useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. It also provides an advanced netcat implementation (ncat), a utility for comparing scan results (ndiff), and a packet generation and response analysis tool (nping).

Proxychains-ng is a preloader which hooks calls to sockets in dynamically linked programs and redirects them through one or more SOCKS or HTTP proxies.

SDB is a simple key/value database based on djb's cdb disk storage that supports JSON and array introspection.

Aircrack-ng is a complete suite of tools to assess WiFi network security. It focuses on different areas of WiFi security: monitoring, attacking, testing, and cracking. All tools are command-line driven, which allows for heavy scripting.

Arp-scan is a tool that uses ARP to discover and fingerprint IP hosts on the local network.

Radare2 is a complete framework for reverse-engineering, debugging, and analyzing binaries. It is composed of a set of small utilities that can be used together or independently from the command line.

Radare2 is built around a scriptable disassembler and hexadecimal editor that support a variety of executable formats for different processors and operating systems, through multiple back ends for local and remote files and disk images.

It can also compare (diff) binaries with graphs and extract information like relocation symbols. It is able to deal with malformed binaries, making it suitable for security research and analysis.

This package provides a tool to demonstrate how easy it is to gain unauthorized access to a system by automatically attempting logins and passwords. It supports a wide range of protocols including SSH, SMTP and HTTP.

This package implements file encryption according to the https://age-encryption.org/v1 specification. It features small explicit keys, no configuration options, and Unix-style composability. This package provides a command line interface (CLI) tools.

Reaver performs a brute force attack against an access point's Wi-Fi Protected Setup (WPS) PIN. Once the PIN is found, the WPA passphrase can be recovered and the AP's wireless settings can be reconfigured.

Fish (friendly interactive shell) is a shell focused on interactive use, discoverability, and friendliness. Fish has very user-friendly and powerful tab-completion, including descriptions of every completion, completion of strings with wildcards, and many completions for specific commands. It also has extensive and discoverable help. A special help command gives access to all the fish documentation in your web browser. Other features include smart terminal handling based on terminfo, an easy to search history, and syntax highlighting.

Portable shared-memory files and mapping helpers for Go.

A small library for watching filesystem changes, used by kitty's watch kitten.

Kitty is a fast and featureful GPU-based terminal emulator:

• Offloads rendering to the GPU for lower system load and buttery smooth scrolling. Uses threaded rendering to minimize input latency.

• Supports all modern terminal features: graphics (images), unicode, true-color, OpenType ligatures, mouse protocol, focus tracking, bracketed paste and several new terminal protocol extensions.

• Supports tiling multiple terminal windows side by side in different layouts without needing to use an extra program like tmux.

• Can be controlled from scripts or the shell prompt, even over SSH.

• Has a framework for Kittens, small terminal programs that can be used to extend kitty's functionality. For example, they are used for Unicode input, hints, and side-by-side diff.

• Supports startup sessions which allow you to specify the window/tab layout, working directories and programs to run on startup.

• Allows you to open the scrollback buffer in a separate window using arbitrary programs of your choice. This is useful for browsing the history comfortably in a pager or editor.

Alacritty is a GPU-accelerated terminal emulator with a strong focus on simplicity and performance. With such a strong focus on performance, included features are carefully considered and you can always expect Alacritty to be blazingly fast. By making sane choices for defaults, Alacritty requires no additional setup. However, it does allow configuration of many aspects of the terminal. Note that you need support for OpenGL 3.2 or higher.

Upstream Slang shader compiler and its runtime modules, relinked against Guix's glibc and C++ libraries. Includes upstream license and bundled-dependency notices. Required by Kitty's shader pipeline.

purego lets Go programs call C functions without using cgo, by loading shared libraries and dispatching into them at runtime.

A drop-in, SIMD-accelerated replacement for Go's standard encoding/base64 package.

Fonts and configuration files extracted from the official Tor Browser bundle, matching the torbrowser version in this channel.

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.

This package is the full featured tor which is needed for running relays, bridges or directory authorities. If you just want to access the Tor network or to setup an onion service you may install tor-client instead.
