[Twisted-Python] Specification / RFC of the twisted.conch.ssh.keys.Key.privateBlob implementation

[Adi Roiban]

Hi,

Does anyone know what specifications / RFC is used for implementing
twisted.conch.ssh.keys.Key.privateBlob ?

https://github.com/twisted/twisted/blob/trunk/twisted/conch/ssh/keys.py#L577

I could not find the over-the-wire format for private keys... as I
supposed that private keys should not be put on the wire, in the first
place.

I did find a SSH agent draft
https://tools.ietf.org/html/draft-ietf-secsh-agent-02#section-1.4.1
but the format is different than the one from the docstring.

In twisted privateBlob is only used to support twisted.conch.ssh.agent

Is anyone using this method ?

Thanks!
