demeuk 4.2.0

CLI tool to remove invalid chars from a corpus.

Demeuk

Demeuk is a simple tool to clean up corpora (like dictionaries) or any dataset containing plain text strings. Example use cases are: cleaning up language dictionaries, password sets (like for example RockYou) or any file / stdin containing plain text strings.

In those corpora you'll find encoding mistakes that have been made, or you want to remove some parts of a line. Instead of creating a huge bash oneliner you can use demeuk to do all your cleaning.

Example usages:

• Cutting
• Length checking
• Encoding fixing

Demeuk is written in Python3, this means of course that it is slower than for example cut. However, Demeuk is written multithreaded and thus can use all your cores. Besides this Demeuk can easily be extended to match your needs.

This application is part of the CERBERUS project that has received funding from the European Union's Internal Security Fund - Police under grant agreement No. 82201
