Rust Requires Chilkat v11.0.0+

DKIM Signature using Windows Current User Certificate Store

See more DKIM / DomainKey Examples

This is a Windows-specific example to load a certificate from the Current User (registry-based) certificate store, and then use the certificate's associated private key for a DKIM signature. Rust

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

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

// The LoadByCommonName method searches the Windows Local Machine and Current User 
// registry-based certificate stores for a certificate having the common name specified. 
// If found, the certificate is loaded and ready for use.
if cert.load_by_common_name("My Certificate ABC").is_err() {
    println!("{}", cert.last_error_text());
    return;
}

// The certificate must have an associated private key installed, and it must be a
// private key that has been marked "exportable" when it was originally installed.
if !cert.has_private_key() {
    println!("This certificate does not have a private key available.");
    return;
}

let priv_key = chilkat::PrivateKey::new();
if cert.get_private_key(&priv_key).is_err() {
    println!("{}", cert.last_error_text());
    return;
}

let dkim = chilkat::Dkim::new();

// Load the private key into the DKIM object:
if dkim.set_dkim_private_key(&priv_key).is_err() {
    println!("{}", dkim.last_error_text());
    return;
}

// The private key has been loaded into the DKIM object.  See the other DKIM
// examples for guidance on how to create a DKIM signature...
