Module keygen 

OpenSSH key generation, loading, and fingerprinting.

Pure-Rust via the [ssh-key] crate. Generated keys are written in the standard OpenSSH private-key format (PEM-armored, PKCS#8-style) and the accompanying public key in the single-line authorized_keys format.

Examples

use std::path::Path;
use gitway_lib::keygen::{KeyType, generate, write_keypair};

let key = generate(KeyType::Ed25519, None, "user@host").unwrap();
write_keypair(&key, Path::new("/tmp/id_ed25519"), None).unwrap();

Errors

All operations return GitwayError. Cryptographic failures (RNG, encryption) and I/O failures are both folded into that type; the caller distinguishes via the is_* predicates.

Zeroization

ssh_key::PrivateKey holds its secret scalar inside a type that zeroes itself on drop. Passphrase material supplied to write_keypair and change_passphrase is passed by reference wrapped in Zeroizing so the caller retains ownership of the zeroization lifecycle.

Enums

KeyType

The set of key algorithms gitway keygen can produce.

Functions

change_passphrase

Changes (or adds, or removes) the passphrase on an existing OpenSSH private key.

extract_public

Extracts the public key from a private-key file and writes it to out.

fingerprint

Returns the OpenSSH-style fingerprint string for a public key.

generate

Generates a new keypair of the requested type.

write_keypair

Writes a keypair to disk.
