Load Default Certificate from Smart Card or Token

See more Certificates Examples

Chilkat contains internal logic to examine a connected smart card or USB token, and will make decisions based on make/model to successfully interact with the hardware. When faced with a new smartcard or token, the best starting point is to call LoadFromSmartcard with an empty string argument to see what Chilkat discovers. Rust

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

// If you know the smart card PIN, it's good to set it prior to loading from the smartcard/USB token.
cert.set_smart_card_pin("12345678");

// To let Chilkat discover what smartcard or token is connected, pass an empty string to LoadFromSmartcard.
// When testing in this way, it's best to have only a single smartcard or token connected to the system.
if cert.load_from_smartcard("").is_err() {
    println!("{}", cert.last_error_text());
    println!("Certificate not loaded.");
    return;
}

// The LastErrorText property on all Chilkat objects will contain 
// information even when the method call is successful.
// You can examine the LastErrorText to see what Chilkat found and
// what decisions were made.
// 
// For example, if a certificate was successfully loaded via LoadFromSmartcard,
// but then signing failed, such as w/ Pdf, XmlDSig, CAdES, etc.,
// then we would want to examine the LastErrorText from the call to
// LoadFromSmartcard to get detailed information about the card.
println!("{}", cert.last_error_text());

println!("Found: {} serial={}", cert.subject_dn(), cert.serial_number());
