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

ctf-cryptotool's Issues

Tool not working

Hello! I'm not getting anything when trying your example text "nGmni Tskcxipo esdskkxgmejve". The output is:

ic (0.043076923076923075, 26)
Traceback (most recent call last):
  File "/root/CTF-CryptoTool/decoder.py", line 74, in <module>
    if s[0] == s[4]:
IndexError: list index out of range

In decoder.py,

line 73:	s = string.split(' ')
line 74:	if s[0] == s[4]:

I think you should check the length first to avoid IndexError.
