# Example Package
CoralPay Python SDK for PGP Encryption on CoralPay's C'Gate
============================================================
This is the Python SDK for integrating with CoralPay's Cgate USSD payment gateway.
It handles the encryption of the requests to C'Gate and the decryption of the response from C'Gate.
It uses the imported C'Gate public PGP key for the encryption and it uses your private PGP key and Passphrase for Decrypting the responses from C'Gate.
This SDK has a hard dependency on GnuPG and runs on Windows and Unix-based machines.
