Build Python + M2Crypto Example program for me

'd like to see an example script(s) for M2Crypto, and the docs don't have any which are all that useful for me. I'd like the script(s) to do the following things. 1- Create an RSA public and private key. 1a- Export these to files. 2- Use your public and private key, and a public key generated separately (by running 1 a separate time), to privately encode a message, so that only the owner of the new key can decode it. 3- Create a key-signature for a given string. ## Deliverables Please list all libraries that will be used.
