See test.py for unit tests and additional sample usage.

========

SAMPLE USE:

# Read "private_rsa_key.pem", make private RSA key, sign something, verify
>>> with open("private_rsa_key.pem", "rb") as kf: data = kf.read()
... key_dict = parse(data)
... key = get_key(key_dict)
... signature = key.sign(b"Hello.", None)
... assert key.verify(b"Hello.", signature)

# Read "rsa_cert.pem", make public RSA key, verify some signature, print
>>> with open("rsa_cert.pem", "rb") as cf: data = cf.read()
... cert_dict = parse(data)
... key = get_key(cert_dict)
... assert key.verify(b"Hello.", my_signature)
... print cert_dict["subject"]
... print cert_dict["body"]

# Return "nice" public and private key functions from a key object
>>> f_my_public = f_public(key)
... f_my_private = f_private(key)
... msg = b"hello"
... assert msg == f_my_public(f_my_public(msg))
... assert msg == f_my_private(f_my_public(msg))
