Is there a way to use python to encrypt / decrypt a file (something like Axcrypt)?
What about this SO Q & A , which talks about encryption / decryption using PGP?
check http://github.com/slideinc/PyECC , http://sourceforge.net/projects/cryptopy/ and http://www.dlitz.net/software/pycrypto/ (everything was found by searching for "crypto" on http : //pypi.python.org/pypi )
Go here in python docs for modules available for encryption: http://docs.python.org/library/crypto.html
