Crate thrussh_keys

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).

 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))
     }
 }

Functions

check_known_hosts	Check whether the host is known, from its standard location.
check_known_hosts_path	Check that a server key matches the one recorded in file path.
decode_openssh	Decode a secret key given in the OpenSSH format, deciphering it if needed using the supplied password.
decode_pkcs5	Decode a secret key in the PKCS#5 format, possible deciphering it using the supplied password.
decode_secret_key	Decode a secret key, possibly deciphering it with the supplied password.
