Create a large poster by building it from
multiple pages and/or printing it on large media. It expects as input a
PDF file, normally printing on a single page. The output is again a
PDF file, maybe containing multiple pages together building the
poster.
The input page will be scaled to obtain the desired size.

This is much like 'poster' does for Postscript files, but working
with PDF.

For more information please refer to the manpage or visit
the project homepage https://pdfposter.readthedocs.io/

The eSpeak NG (Next Generation) Text-to-Speech program is a speech
synthesizer that supports 100 languages and accents. It is based
on the eSpeak engine created by Jonathan Duddington. It uses
spectral formant synthesis by default which sounds robotic, but can
be configured to use Klatt formant synthesis or MBROLA to give it a
more natural sound.

Many default regular expression parsers have unbounded worst-case complexity.
Regex matching may be quick when presented with a matching input string.
However, certain non-matching input strings can make the regular expression
matcher go into crazy backtracking loops and take ages to process. This can
cause denial of service, as the CPU will be stuck trying to match the regex.

This tool is designed to:
* find regular expressions which are vulnerable to ReDoS
* give an example malicious string which will cause catastrophic backtracking

Supports:
- C#
- JavaScript/TypeScript (requires node to be installed)
- JSON
- Python
- YAML

A tool that looks for files accessible on web servers that shouldn't be public
and can pose a security risk.

Typical examples include publicly accessible git repositories, backup files
potentially containing passwords or database dumps. In addition, it contains
a few checks for other security vulnerabilities.

A utility to reset the password of any user that has a valid local account on your Windows system.
Supports all Windows from NT3.5 to Win8.1, also 64 bit and also the Server versions (like 2003, 2008, 2012)
You do not need to know the old password to set a new one.
It works offline, that is, you have to shutdown your computer and boot off a CD or USB disk to do the password reset.
Will detect and offer to unlock locked or disabled out user accounts.
There is also a registry editor and other registry utilities that works under linux/unix, and can be used for other things than password editing.

This small tool allows the user to graphically examine ddrescue's map files in a user friendly GUI application. The Main window displays a block grid with each block's color representing the block types it contains. Many people know this type of view from defragmentation programs.

Forensic Registry EDitor (fred) is a cross-platform M$ registry
hive editor with special features useful during forensic
analysis.

Python tools to analyze security characteristics of MS Office and OLE files (also called Structured Storage, Compound File Binary Format or Compound Document File Format), for Malware Analysis and Incident Response (DFIR)

Signing Party is a collection for all kinds of pgp related things,
including signing scripts, party preparation scripts etc.

caff is a script that helps you in keysigning. It takes a list of
keyids on the command line, fetches them from a keyserver and calls
GnuPG so that you can sign it. It then mails each key to all its email
addresses - only including the one UID that we send to in each mail.

pgp-clean takes a list of keyids on the command line and outputs an
ascii-armored keyring on stdout for each key with all signatures
except self-signatures stripped. Its use is to reduce the size of keys
sent out after signing. (pgp-clean is a stripped-down caff version.)

gpg-key2ps will output a PostScript file which has your Key-ID, UIDs
and fingerprint nicely formatted for printing paper slips to take with
you to a signing-party.

Given one or more key-ids, gpg-mailkeys mails these keys to their
owners. You use this after you've signed them. By default, the mails
contain a standard text and your name and address as the From (as
determined by the sendmail command).

gpglist takes a keyid and creates a listing showing who signed your
user IDs.

gpgsigs was written to assist the user in signing keys during a
keysigning party. It takes as input a file containing keys in gpg
--list-keys format and prepends every line with a tag indicating if
the user has already signed that uid.

keylookup is a wrapper around gpg --search, allowing you to search for
keys on a keyserver. It presents the list of matching keys to the user
and allows her to select the keys for importing into the GnuPG
keyring.

A terminal client for redis with auto-completion and syntax
highlighting. IRedis lets one type Redis commands, and it displays results.

IRedis is an alternative for redis-cli. In most cases, IRedis behaves
exactly the same as redis-cli. IRedis will prevent accidentally
running dangerous commands.

xonsh is a Python-powered, Unix-gazing shell language and command prompt. The language is a superset of Python 3.5+ with additional shell primitives. xonsh (pronounced conch) is meant for the daily use of experts and novices alike.

Facilitate working with various versions of Ansible 2.9 and newer.

Byobu is a Japanese term for decorative, multi-panel screens that serve as
folding room dividers. As an open source project, Byobu is an elegant
enhancement of the otherwise functional, plain, practical GNU Screen. Byobu
includes an enhanced profile and configuration utilities for the GNU screen
window manager, such as toggle-able system status notifications.

A cmdline utility to search DuckDuckGo from the terminal. Similar to googler for Google.

Unlike the web interface, you can specify the number of search results you would like to see per page. It's more convenient than skimming through 30-odd search results per page. The default interface is carefully designed to use minimum space without sacrificing readability.

While fd does not seek to mirror all of find's powerful functionality,
it provides opinionated defaults for 80% of the use cases.

This utility will split your console into a multiple panes of genuine
technobabble, perfectly suitable for any Hollywood geek melodrama.
It is particularly suitable on any number of computer consoles in the
background of any excellent schlock technothriller.
