Struct KnownHosts 

pub struct KnownHosts { /* private fields */ }

Known SSH host keys for server verification (TOFU model)

On first connection to a server, the key is saved to a known_hosts file. On subsequent connections, the presented key is verified against the saved one. This prevents MITM attacks after the initial connection.

Implementations

impl KnownHosts

pub fn load(path: &Path) -> Self

Load known hosts from file, or create empty if file doesn’t exist

pub async fn verify( &self, host: &str, port: u16, key: &PublicKey, ) -> Result<bool, Error>

Check a server’s public key against known hosts. Returns Ok(true) if the key matches or was newly saved (TOFU). Returns Ok(false) if the key does NOT match a previously saved key (possible MITM).

Trait Implementations

impl Clone for KnownHosts

fn clone(&self) -> KnownHosts

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
