osshkeys

Description

A Rust library to handle OpenSSH key and other common SSH key

The main function of this library is to read, write different formats of SSH keys. Also, it provide the ability to generate a key, sign and verify data.

Current Status

The library is still under development, so there are some functions that haven't implemented. Some api may also change in the future.

Example

```rust

[macro_use]

extern crate hex_literal; use osshkeys::{KeyPair, KeyType, Key as _, PublicPart as _, PrivatePart as _}; use osshkeys::keys::FingerprintHash;

fn main() { let keyfile = std::fs::readtostring("assets/opensshed25519enc").unwrap(); let keypair = KeyPair::from_keystr(&keyfile, Some(b"12345678")).unwrap();

// Get the public key
let publickey = keypair.clone_public_key().unwrap();

// Get the key type
assert_eq!(keypair.keytype(), KeyType::ED25519);

// Get the fingerprint
assert_eq!(keypair.fingerprint(FingerprintHash::MD5).unwrap(), hex!("d29552b0c87d7ff1acb3c2229e783321"));

// Sign some data
const SOME_DATA: &[u8] = b"8Kn9PPQV";
let sign = keypair.sign(SOME_DATA).unwrap();

assert_eq!(sign.as_slice(), hex!("7206f04ef062ec35f8fb9f9e8a17ec023070ecf5f6e1021ea2af73137b1b832bba08766e5ad95fdca81af37b27898428f9a7dbeb044dd550afeb46efb94fe808").as_ref());
assert!(publickey.verify(SOME_DATA, &sign).unwrap());

} ```
