CryptoAlgo

Encrypt your text/image via ECC algorithm using standalone binary

Python3 executable based Crypto program is licensed under GNU LGPLv3 (See LICENSE). The crypto algorithm is based on Simple Elliptic Curve Cryptography(Ecc) algorithm made available by py-seccure( https://github.com/bwesterb/py-seccure)

Usage:

1. Download/extract the zipped file or clone this repository to your home directory {$Crypto}

2. Follow the steps as mentioned below,

   a). cd to ${Crypto}/CryptoAlgo/CryptoAlgo/ folder

    $./crypt/crypt
   
    Command line usage as follows:
    ==============================
    ./crypt/crypt keygeneration - for generating the public key
    ./crypt/crypt encrypt - for encrypting the text
    ./crypt/crypt decrypt - for decrypting the text
   

b). Generate the public key

    $./crypt/crypt keygeneration
      
    Brought to you by Crypto Algo!!
    ==============================

    Please enter your private key/passphrase to generate a public key
    PassPhrase:

c). Encrypt the message (image to be encrypt must be renamed as "file.jpg" and stored in $Crypto/crypt/ folder)
