kuronuri

A way to hide to text in japan, is KURONURI culture. This tool implementation that way by Golang.

When you take over operation from your senior, you may look legacy shell script from old.

#!/bin/bash

USERID=admin
PASSWORD=password1234

wget --post-data="userid=$USERID&$PASSWORD" http://192.168.0.1:8080

very, very, very worst!!

This makes you want to encrypt a little bit, doesn't it?
But, If you encrypt all text, anyone can't see what's inside.
If possible, you want to encrypt a part of text. This tool help you!

usage

This tool encrypt or decrypt a part of text, and create temporary file and run script.
So, secret keyword can't know anyone , and we can know script's inside.

The earlier script example.

kuronuri.exe -noRun -dst=output.sh (USERID=;PASSWORD=:hogepassword) target.sh

This tool encrypt the sentence after the key word.

#!/bin/bash

USERID=Et3dTygDs6uOdxYiAA9cHWvrNmOvTRs1g-TQ9OTyBsrs
PASSWORD=VbRl8yLqWAbXossvQRlJRgJavonBaINn4hJvy5mJJtqkAa0wqH7RBg==

wget --post-data="userid=$USERID&$PASSWORD" http://192.168.0.220:8080

A case of decryption, ")" is opposite direction.

kuronuri.exe )USERID=;PASSWORD=:hogepassword( output.sh

ver easy! (Bob Ross said)

You want to hide your local address too if you can by another key word.

kuronuri.exe -noRun -dst=output.sh (USERID=;PASSWORD=:hogepassword) (//:fugapassword) auth.sh

You could.

#!/bin/bash

USERID=qDCHaNFLiHI7UtFM_r2_dZzGUacQnFLfXZ8gOw1gsoay
PASSWORD=T_EHdS2C6RAUhstj3PIi124uRwhkWgEE_A67Z7e4NUx9rtso2IX21g==

wget --post-data="userid=$USERID&$PASSWORD" http://eNU4qWl3qJ7lVxL14lDTrMXkyUQuuMXwzM9nsbowd8ZVDJFyC1XJ5KRXJsUvAA==

Way to decode by two keywords.

kuronuri.exe -noRun )USERID=;PASSWORD=:hogepassword( )//:fugapassword( output.sh

")" is opposite direction again. ver easy!
