SFTP Host Key Fingerprint

See more SFTP Examples

Demonstrates how to get the SSH server's host key fingerprint after connecting. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let sftp = chilkat::SFtp::new();

let hostname = "sftp.example.com".to_string();
let port = 22;
if sftp.connect(&hostname, port).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Get the classic MD5 fingeprint
let md5_fingerprint = sftp.host_key_fingerprint();
println!("{}", md5_fingerprint);

// Sample output:
// ssh-rsa 3072 21:b0:d8:41:4e:ef:78:10:20:af:01:b7:71:5d:eb:94

// Starting in Chilkat v9.5.0.92, we can also get the SHA256 fingerprint.
// (it is also possible to get fingerprints using other hash algorithms such as SHA384, SHA512, etc.)

let mut include_key_type = true;
let mut include_hash_name = true;
let mut sha256_fingerprint = sftp.get_host_key_fp("SHA256", include_key_type, include_hash_name).unwrap_or_default();
