Thanks, that worked! One more question: How do I authenticate with public keys? What I am trying to get this to do it to authenticate based on the public key, not based on the password. The program will have a list of trusted public keys, and only allow those to connect. They could use a password, but if they have the wrong public key, I don't want them to connect.

I am trying to write an encrypted P2P program (cryptic6.sourceforge.net).

I am trying to understand twisted's ssh. Thanks to the helpful people on #twisted I have am able to get the twisted client to send messages to the twisted server. This works when I use the keys provided in the example. However when I try to generate my own keys it always complains that they are not password.

This is the code I am using to generate public/private key pairs:

twisted.scripts.ckeygen.generateRSAkey({'bits':1048,'filename': os.path.join(os.path.expanduser('~'),'.cryptic6/keys'),'pass':pass)

This is the error I get:

The problem is on the next line: 'ssh-rsa': keys.getPrivateKeyObject(data=privateKey)

That means that getPrivateKeyObject doesn't expect the key to be encrypted. If it is, you need to also pass in the passphrase kwarg with the passphrase.
