Encrypt MIME using PEM Certificate

See more MIME Examples

Encrypt MIME using a PEM certificate. Rust

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

let mime = chilkat::Mime::new();

// Create a simple MIME message to be encrypted:
let _ = mime.add_header_field("Content-Type", "text/plain").is_ok();
let _ = mime.add_header_field("abc", "123").is_ok();
mime.set_body("This is a test");

let cert = chilkat::Cert::new();
if cert.load_from_file("qa_data/pem/mf_public_rsa.pem").is_err() {
    println!("{}", cert.last_error_text());
    return;
}

// Encrypt the MIME.
if mime.encrypt(&cert).is_err() {
    println!("{}", mime.last_error_text());
    return;
}

// Display the MIME:
println!("{}", mime.get_mime().unwrap_or_default());

// The resulting S/MIME looks like this:

// Content-Type: application/x-pkcs7-mime; name="smime.p7m"; smime-type="enveloped-data"
// abc: 123
// Content-Disposition: attachment; filename="smime.p7m"
// Content-Transfer-Encoding: base64
