CTF-CryptoTool

Installation

This tool will run on python3

git clone https://github.com/karma9874/CTF-CryptoTool.git
cd CTF-CryptoTool 
pip3 install -r requirements.txt

Usage

Just throw the cipher to it

python3 decoder.py 
Enter the text  : Feed the cipher text
Enter Key       : Enter key if you know any (optional)
Enter flag 	    : Enter some letters of the flag if you know (optional)
				Eg: While playing picoCTF you can enter the flag as picoCTF so it can match that text with the ouputs otherwise you may get much more bogus strings
