Rust Requires Chilkat v11.0.0+

Export Public Key from USB Token or Smartcard using the Apple Keychain

See more Apple Keychain Examples

Demonstrates how to export a public key from a USB token or smart card via the Apple Keychain. Rust

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

let cert = chilkat::Cert::new();

// On MacOS and iOS, the LoadByCommonName function will search the Apple Keychain for the matching certificate.

// A digital certificate's Common Name (CN) is a field in the certificate that specifies the name of the entity the 
// certificate is issued to. It is often used to identify the domain name, hostname, or organization the certificate represents. 

// For example:
// - In an SSL/TLS certificate for a website, the CN typically contains the domain name (e.g., "www.example.com").
// - For certificates representing individuals or organizations, the CN might include the person's name or the organization's name.

// The CN is part of the certificate's Subject field and is crucial for verifying that the certificate corresponds 
// to the intended entity, especially in SSL/TLS communications.

if cert.load_by_common_name("Test 2048 bit RSA").is_err() {
    println!("{}", cert.last_error_text());
    return;
}

let pub_key = chilkat::PublicKey::new();
let _ = cert.get_public_key(&pub_key);

if pub_key.save_pem_file(false, "rsaKeys/Test2048Rsa.pem").is_err() {
    println!("{}", pub_key.last_error_text());
