############################################################################# # ABOUT # ############################################################################# Author: Nagaraja. T Date: 15th January, 2014 Verion: 1.0.1 License: GPL Homepage: https://github.com/naga2raja/CryptoG CryptoG is simple Encryption/Decryption program using AES,DES and RSA algorithms. This CryptoG is written purely in python. The following types of Encryption & Decryption is available using CryptoG 1) AES - AES Encryption & Decryption 2) DES - Single DES Encryption & Decryption - Triple DES Encryption & Decryption 3) RSA - Private Key Encryption & Decryption - Public Key Encryption & Decryption ############################################################################# # PRE-REQUISITES # ############################################################################# CryptoG program requires pyDES package (Zip available along with the package). Please install it using the following command before running CryptoG. $ unzip pyDes-2.0.1.zip $ cd pyDes-2.0.1/ $ sudo python setup.py install ############################################################################# # Credits # ############################################################################# - Todd Whiteman: For pyDes package - Brandon Sterne: For his excellent writting on RSA - Godwin Ponsam: For making me to write this program ############################################################################# # CryptoG usage # ############################################################################# CryptoG performs both Encryption and Decryption. The program accepts the input file named "testfile.txt". Encryption is performed before decryption. ****************** AES ALGORITHM (Encrytion and Decryption) *************** AES Encryption: (Input file : testfile.txt) $ python cryptog.py 1. Encrytion 2. Decryption Enter your choice : 1 1. AES Encryption 2. DES Encryption 3. RSA Encryption Enter your choice : 1 AES Encrytion Started ... Encrypting file: testfile.txt Encryption complete. Total Time conceeded by AES 0:00:10.877200 After encryption is done, a file called testfile_encrytped_AES.txt will be created. This file contains the encrypted contents of testfile.txt. AES Decryption: (Input file : testfile_encrytped_AES.txt) #An encrypted file where encryption done using AES. $ python cryptog.py 1. Encrytion 2. Decryption Enter your choice : 2 *** Please perform encryption before proceesing with decryption *** 1. AES Decryption 2. DES Decryption 3. RSA Decryption Enter your Choice :1 AES Decrytion Started ... Decrypting file: testfile_encrytped_AES.txt Decryption complete. Total Time conceeded by AES Decryption 0:00:11.241573 After decyption is done, a file called testfile_decrypted_AES.txt will be created with original text. ******************************** DES ALGORITHM (single & triple DES) *************************** Single DES Encryption: (input file : testfile.txt) 1. Encryption 2. Decryption Enter your Choice:1 1. AES Encryption 2. DES Encryption 3. RSA Encryption Enter your Choice :2 1. Single DES Encryption 2. Triple DES Encryption Enter your Choice:1 DES Encryption Started... Total Time conceeded by DES 0:00:05.459710 fter encryption is done, a file called testfile_encrytped_single_DES.txt will be created. This file contains the single DES encrypted contents of testfile.txt. Single DES Decryption: (input file : testfile_encrytped_single_DES.txt ) 1. Encryption 2. Decryption Enter your Choice:2 *** Please perform encryption before proceesing with decryption *** 1. AES Decryption 2. DES Decryption 3. RSA Decryption Enter your Choice :2 1. Single DES Decryption 2. Triple DES Decryption Enter your Choice:1 Single DES Decryption Started... Total Time conceeded by DES 0:00:05.441380 ### This format is same for Triple DES Encryption and Decryption algorithm ******************************************* RSA ALGORITHM (private key & public key algorithm) ******************* Private Key Encryption: (input file : testfile.txt) 1. Encryption 2. Decryption Enter your Choice:1 1. AES Encryption 2. DES Encryption 3. RSA Encryption Enter your Choice :3 1. Private Key Encryption 2. Public Key Encryption Enter your Choice:1 RSA Private Key Encrytion Started ... Total Time conceeded by RSA Private Key Encryption 0:01:55.643147 Private Key Decryption: (input file : testfile_encrypted_RSA_private.txt) 1. Encryption 2. Decryption Enter your Choice:2 *** Please perform encryption before proceesing with decryption *** 1. AES Decryption 2. DES Decryption 3. RSA Decryption Enter your Choice :3 1. Private Key Decryption 2. Public Key Decryption Enter your Choice:1 RSA Private Key Decrytion Started ... Total Time conceeded by RSA Private Key Decryption 0:01:30.029714 ### This steps are same for RSA Public Key encryption also.
