python_rsa encryption and decryption

Python for using encryption and encryption rsa, including public key encryption private key to decrypt the private key to decrypt the encrypted public key. (Need to install M2Crypto library).

#!/usr/bin/env python

Installation instructions library

Download M2Crypto library:

https://github.com/martinpaljak/M2Crypto

Or: https://pypi.python.org/pypi/M2Crypto

Dependent libraries: openssh-devel gcc swig (three libraries can be used directly mounted on CentOS yum)
