30 You can use the :py:func:`rsa.newkeys` function to create a keypair:
32     >>> import rsa
33     >>> (pubkey, privkey) = rsa.newkeys(512)
35 Alternatively you can use :py:meth:`rsa.PrivateKey.load_pkcs1` and
36 :py:meth:`rsa.PublicKey.load_pkcs1` to load keys from a file:
38     >>> import rsa
41     >>> privkey = rsa.PrivateKey.load_pkcs1(keydata)
61     >>> (pubkey, privkey) = rsa.newkeys(512, poolsize=8)
97 To encrypt or decrypt a message, use :py:func:`rsa.encrypt` resp.
98 :py:func:`rsa.decrypt`. Let's say that Alice wants to send a message
105     >>> import rsa
106     >>> (bob_pub, bob_priv) = rsa.newkeys(512)
117     >>> import rsa
118     >>> crypto = rsa.encrypt(message, bob_pub)
122     >>> message = rsa.decrypt(crypto, bob_priv)
139 :py:class:`rsa.pkcs1.DecryptionError`. If you want to be *sure*, use
140 :py:func:`rsa.sign`.
142     >>> crypto = rsa.encrypt(b'hello', bob_pub)
144     >>> rsa.decrypt(crypto, bob_priv)
147     rsa.pkcs1.DecryptionError: Decryption failed
153     :py:class:`rsa.pkcs1.DecryptionError` exception. It shows where

174     >>> signature = rsa.sign(message, privkey, 'SHA-1')
177 possible, check the :py:func:`rsa.sign` function documentation for
182 private key on remote server). To hash a message use the :py:func:`rsa.compute_hash`
183 function and then use the :py:func:`rsa.sign_hash` function to sign the hash:
186     >>> hash = rsa.compute_hash(message, 'SHA-1')
187     >>> signature = rsa.sign_hash(hash, privkey, 'SHA-1')
189 In order to verify the signature, use the :py:func:`rsa.verify`
193     >>> rsa.verify(message, signature, pubkey)
197 :py:class:`rsa.pkcs1.VerificationError` is thrown:
200     >>> rsa.verify(message, signature, pubkey)

215 Instead of a message you can also call :py:func:`rsa.sign` and
216 :py:func:`rsa.verify` with a :py:class:`file`-like object. If the
