Apple Keychain - Get Certificate by Common Name

See more Apple Keychain Examples

Retrieves the certificate from the Apple Keychain that matches the specified common name (CN).

Note: This example requires Chilkat v10.0.0 or greater.

Rust

// On MacOS or iOS, this searches both the Default keychains and System keychains for the certificate
// having the specified CN.
let cert = chilkat::Cert::new();
if cert.load_by_common_name("Certum CA").is_err() {
    println!("{}", cert.last_error_text());
    return;
}

println!("{}", cert.subject_dn());

// Note: In the Apple Keychain, a certificate with its private key represents an identity because it combines the certificate and its private key.
// When Chilkat loads a certificate from the Apple Keychain, it also gets the associated private key.
// You can simply use the cert in other places in Chilkat where a cert w/ private key is required.
let cert2 = chilkat::Cert::new();
if cert2.load_by_common_name("Chilkat Software, Inc.").is_err() {
    println!("{}", cert2.last_error_text());
    return;
}

println!("{}", cert2.subject_dn());
let has_priv_key = cert2.has_private_key();
println!("Has private key: {}", has_priv_key);

println!("Success.");
