This crate contains methods to deal with SSH keys, as defined in crate Thrussh. This includes in particular various functions for opening key files, deciphering encrypted keys, and dealing with agents.
The following example (which uses the openssl
feature) shows how
to do all these in a single example: start and SSH agent server,
connect to it with a client, decipher an encrypted private key
(the password is b"blabla"
), send it to the agent, and ask the
agent to sign a piece of data (`b"Please sign this", below).
use thrussh_keys::*; use futures::Future;
#[derive(Clone)] struct X{} impl agent::server::Agent for X { fn confirm(self, _: std::sync::Arckey::KeyPair) -> Box<dyn Future<Output = (Self, bool)> + Send + Unpin> { Box::new(futures::future::ready((self, true))) } }
