1. Was this executable stripped?
yes
2. How are the password checking functionalities entangled with the operating system?
3. What is the algorithm used to check the validity of a password?
4. Can you break this password checker, i.e., implementing a generator of valid passwords? You must send 16 different valid passwords by email to pascal+sre25@mod-p.ch before Mar. 24th, 2025, 12h00 CET to validate this lab and get 5 points.

The "data" directory is intended to hold data files that will be used by this module and will
not end up in the .jar file, but will be present in the zip or tar file. Typically, data
files are placed here rather than in the resources directory if the user may need to edit them.
An optional data/languages directory can exist for the purpose of containing various Sleigh language
specification files and importer opinion files.
The data/buildLanguage.xml is used for building the contents of the data/languages directory.
The skel language definition has been commented-out within the skel.ldefs file so that the
skeleton language does not show-up within Ghidra.
See the Sleigh language documentation (docs/languages/index.html) for details Sleigh language
specification syntax.

<?xml version='1.0' encoding='ISO-8859-1' ?>
<!--
This is an XML file intended to be parsed by the Ghidra help system. It is loosely based
upon the JavaHelp table of contents document format. The Ghidra help system uses a
TOC_Source.xml file to allow a module with help to define how its contents appear in the
Ghidra help viewer's table of contents. The main document (in the Base module)
defines a basic structure for the
Ghidra table of contents system. Other TOC_Source.xml files may use this structure to insert
their files directly into this structure (and optionally define a substructure).
In this document, a tag can be either a <tocdef> or a <tocref>. The former is a definition
of an XML item that may have a link and may contain other <tocdef> and <tocref> children.
<tocdef> items may be referred to in other documents by using a <tocref> tag with the
appropriate id attribute value. Using these two tags allows any module to define a place
in the table of contents system (<tocdef>), which also provides a place for
other TOC_Source.xml files to insert content (<tocref>).
During the help build time, all TOC_Source.xml files will be parsed and validated to ensure
that all <tocref> tags point to valid <tocdef> tags. From these files will be generated
<module name>_TOC.xml files, which are table of contents files written in the format
desired by the JavaHelp system. Additionally, the genated files will be merged together
as they are loaded by the JavaHelp system. In the end, when displaying help in the Ghidra
help GUI, there will be on table of contents that has been created from the definitions in
all of the modules' TOC_Source.xml files.
Tags and Attributes
<tocdef>
-id - the name of the definition (this must be unique across all TOC_Source.xml files)
-text - the display text of the node, as seen in the help GUI
-target** - the file to display when the node is clicked in the GUI
-sortgroup - this is a string that defines where a given node should appear under a given
parent. The string values will be sorted by the JavaHelp system using
a javax.text.RulesBasedCollator. If this attribute is not specified, then
the text of attribute will be used.
<tocref>
-id - The id of the <tocdef> that this reference points to
**The URL for the target is relative and should start with 'help/topics'. This text is
used by the Ghidra help system to provide a universal starting point for all links so that
they can be resolved at runtime, across modules.
-->
<tocroot>
<!-- Uncomment and adjust fields to add help topic to help system's Table of Contents
<tocref id="Ghidra Functionality">
<tocdef id="HelpAnchor" text="My Feature" target="help/topics/my_topic/help.html" />
