Rust Requires Chilkat v11.5.0+

Create CAdES (p7m) Signature using ARSS (Aruba Remote Signing Service)

See more Signing in the Cloud Examples

Demonstrates creating a CAdES (p7m) signature using the Aruba Remote Signing Service. Rust

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

// Load the certificate used for signing.  The certificate's private key is stored on 
// the Aruba.it server and the signing will happen remotely using the
// ARSS (Aruba Remote Signing Service).
// However, we still need the certificate locally (without private key).
let cert = chilkat::Cert::new();
if cert.load_from_file("qa_data/certs/myCert.cer").is_err() {
    println!("{}", cert.last_error_text());
    return;
}

// To sign using the Aruba Remote Signing Service, 
// add the following lines of code to specify your authentication credentials,
// and the ID of the certificate w/ private key on the server to be used.
let json_arss = chilkat::JsonObject::new();

// Set the "service" equal to "ARSS" to tell Chilkat to use ARSS for signing.
let _ = json_arss.update_string("service", "ARSS");
// Specify the certificate ID, such as "AS0"
// This certificate should match the certificate loaded in the above code.
let _ = json_arss.update_string("certID", "YOUR_ARSS_CERT_ID");
let _ = json_arss.update_string("otpPwd", "YOUR_OTP_PWD");

// Specifies the OTP authentication environment.
// 
// Common values are:
//   "demoprod" - Demo/Test environment
//   "prod"     - Production environment
// 
// This value is sent to the ARSS service and determines how the OTP
// authentication is validated.  The correct value depends on the type
// of Aruba account and environment that has been provisioned.
// 
// If signing fails with an authentication-related error, verify that
// the typeOtpAuth value matches the environment associated with the
// ARSS account credentials being used.
let _ = json_arss.update_string("typeOtpAuth", "demoprod");

let _ = json_arss.update_string("user", "YOUR_ARSS_USERNAME");
let _ = json_arss.update_string("userPWD", "YOUR_ARSS_PASSWORD");

// The "endpoint" can be specified starting in Chilkat v11.5.0
let _ = json_arss.update_string("endpoint", "https://app1.firma-remota.it/ArubaSignerService/webresources/signerservice");

let _ = cert.set_cloud_signer(&json_arss).is_ok();

let crypt = chilkat::Crypt2::new();

if crypt.set_signing_cert(&cert).is_err() {
    println!("{}", crypt.last_error_text());
    return;

// The CadesEnabled property applies to all methods that create PKCS7 signatures. 
// To create a CAdES-BES signature, set this property equal to true.
crypt.set_cades_enabled(true);

// You can sign any type of file..
let input_xml_path = "qa_data/e-Invoice.xml".to_string();
let output_p7m_path = "qa_output/signed.p7m".to_string();

// Create the CAdES-BES attached signature, which contains the original data.
// Chilkat will build the .p7m locally, but will (internally) use ARSS
// to do the RSA signing remotely.
