See more Digital Signatures Examples

_LANGUAGE_ example to extract the original file from a .p7m (Signed-Data PKCS7 Format) The .p7m contains the signed contents of the original file.

One use for this example is to extract the XML file from a Fattura Elettronica .p7m signature.

Rust

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

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

let output_file = "testData/xml/original.xml".to_string();
let in_file = "testData/p7m/fattura_signature.p7m".to_string();

// Verify the signature and extract the XML file.
if crypt.verify_p7_m(&in_file, &output_file).is_err() {
    println!("{}", crypt.last_error_text());
    return;
}

println!("Success!");
