r""" Indicates the Unit which was created is not applicable to the given target, and the unit is in an undefined state.

A user in the CTF game. Not all fields may be filled.

Indicates a failure to authenticate with the CTF

A CTF Challenge

Class to manage the threaded evaluation of applicable units against arbitrary targets. Facilitates work queue management and recursion within

A bracket is a specific group of users you play against. PicoCTF calls them "scoreboards". Most CTFs don't implement this, though.

A monitor object recieves notifications from units whenever data, artifacts or flags are found while processing a target. The default monitor

This is used for the DTMF processing operations. Admittedly, it was found online and adapted to work within Katana.

Tracks data about an active download

r""" Utilize python dynamic introspection and loading to locate units either within the default unit list bundled with Katana or in a custom l

r""" Indicates the unit was missing a dependency, and cannot be loaded. The message content is the name of the missing dependency

Receives events from watchdog for newly created files to queue

A simple Katana REPL implemented using the cmd2 module. You should instantiate the manager prior to creating this object. It will then a

A monitor which will save important information needed to run the Repl katana shell.

A Target has two main parts: - Upstream - Raw Data The Upstream is what was passed to the target constructor. In the case o

Helper for aborting inner loops

Indicates that we don't want to evaluate this target. This is normally due to a target that is too short

Provides an interface into a remote CTF platform

This Unit will raise :class:`katana.unit.NotApplicable` if the unit is a URL or a potentially useful file.

r""" This unit base class ensures that the target content is printable, and is also *not* english text (e.g. base64 data, white space, etc.)

r""" This unit base class ensures that the target content contains mostly non-english text.

r""" This unit base class ensures that the target content contains only printable data (that is, data which is not binary/is readable).

Part of the Git Dumper procedure. Download a directory recursively.

Utilizes a regular expression pattern to locate matching sections of the input data. The Unit will raise NotApplicable if the target has no match
