lib.rs:

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 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::*;

 #[derive(Clone)]
 struct X{}
 impl agent::server::Agent for X {
     fn confirm(&self, _: std::sync::Arc<key::KeyPair>) -> Box<dyn Future<Output = bool> + Send + Unpin> {
         Box::new(futures::future::ready(true))
     }
 }
