openssh-keys  

A pure-Rust library to handle OpenSSH public keys.

openssh-keys can parse, print, and fingerprint OpenSSH public keys. It supports the following algorithms:

• RSA
• DSA
• ECDSA (nistp256, nistp384, nistp521)
• ED25519

It can construct RSA and DSA keys from their components using the PublicKey::from_rsa() and PublicKey::from_dsa() functions respectively.

Example

extern crate openssh_keys;

use std::{env, fs, io, path};
use std::io::BufRead;

fn main() {
    let home = env::home_dir().unwrap_or(path::PathBuf::from("/home/core/"));
    let pub_path = home.join(".ssh").join("id_rsa.pub");
    println!("Inspecting '{}':", pub_path.to_string_lossy());
    let file = fs::File::open(&pub_path).expect("unable to open RSA pubkey");
    let reader = io::BufReader::new(file);
    
    for (i, line) in reader.lines().enumerate() {
        let line = line.expect(&format!("unable to read key at line {}", i + 1));
        let pubkey = openssh_keys::PublicKey::parse(&line).expect("unable to parse RSA pubkey");
        println!(" * Pubkey #{} -> {}", i + 1, pubkey.to_fingerprint_string());
    }
}

Some more examples are available under examples.
