D3crypt0r
This projects devotes itself to decrypting various text encryptions algorithms, specifically the likes of Rivest-Shamir-Aldeman(RSA encryption algorithm) and ciphers, mainly the Vigenere and Caeser ciphers and many others.(p.s. encryptions can also be done... since knowledge flows both ways)
Application
Command-Line-Tool:: cryptologer.py
Environment
Python 3.5+
Installation
There are setup files available for installing the project in the /SETUP folder. viz., for both latest Windows and Linux operating systems.
Linux Install: download crypt_linux, it's a zip file. Unzip and run python script alias first then use cryptologer
in the bash.
Windows Install: download mystic_win and go through the installation process. Open the registry key crypt, restart terminal and use cryptologer
.
The required files are auto-saved to C:\Program Files (x86)\D3crytMe!
Bashing Options
cryptoloher -h

Decryptor for Caeser, Vigenere, types of RSA and more...
Optional Arguments
-h, --help show this help message and exit
--decrypt, --dec, -d Performs Decryption
--encrypt, --enc, -e Performs Encryption
--sourcefile SOURCEFILE, --sf SOURCEFILE, -f SOURCEFILE
Input file with ciphertext
--cipher CIPHER, --cip CIPHER, -c CIPHER
Input cipher as text
--key KEY, -k KEY If the key is known (text for vignere, shift for caeser)
--caeser, -C If the cipher is caeser cipher
--vignere, -V If the cipher is vignere cipher
--affine, -A If the cipher is affine cipher
--bacon, -B If the cipher is bacon cipher
--polybius, -P If the cipher is encrypted by a simple 6x6 polybius square
--railfence, -F If railfence encryption is used
--atbash, -T If atbash rotation is done on the plaintext
--substitution, -S If the plaintext in encrypted using simple substitution cipher
--rsa, -R If the cipher is RSA related
--weiner, -W Cracking RSA using Weiner attack
--smalle, -E Cracking RSA provided e is very small
--internal, -I If an internal attack for RSA is being performed
--fermat, -M Fermat\'s attack on the RSA encrypted text
--twin, -N If the RSA public is a product of twin primes, use this
--chinese, -H Using the Chinese Remainder Theorem for cracking RSA from e packets having the same n
Arguments & Usage::
-e
-d
for specifing encryption or decryption:: no default value
-C
-V
-A
-B
-P
-F
-S
-R
-W
-E
-I
any one of these for specifying the kind of cipher/rsa attack:: no default value
-f
for specifying the file containing the data
c
for providing the cipher manually:: not applicable for rsa
-k
for manually typing the key in case of Caeser/Vigenere:: optional
-l
for specifying max probable key length in case of vigenere cipher:: default value=10
File Format & Content
Ciphers:: raw data in text files
RSA:: text files require specifying modulus n, public key e and ciphertext c in seperate lines
The keyword should be followed by its respective value. While encrypting using RSA, use m instead of the general c.
