An open source CTF tool for meaning finding that supports leetspeak.

meaningsearch

A simple package that helps you find meaningful lines of any given input. Especially useful in CTFs.

Meaning search supports Leet and can detect even obfuscated meaningful texts.

How to install

Simply run:

cargo install meaningsearch

to install the package.

How to use

You can use the command below to run a meaning search. End your input with ctrl + D.

meaningsearch <options>

You can also find meaningful lines in the output of a bin using:

cat <somefile> | meaningsearch <options>

--file

You can use the 'file' flag to meaning search a file:

meaningsearch --file <path to file>

--threshhold

By default, the meaning checker deems a line meaningful if it contains 30% meaningful content. You can use the 'threshold' flag to specify a different threshold for your meaning checker. In the following example, we specify a threshold of 80%:

cat <somefile> | meaningsearch -t 0.8

Example

Let's assume we have the following text file called test.txt:

asdasd a dasd ajnafan oas
n00bz d0n'7 w1n!
this is a normal line.
da kadma akj ad

Running the following command on the said text file results in:

$ cat test.txt | meaningsearch -t 0.5
n00bz d0n'7 w1n!
this is a normal line.
