Extract XML from FatturaPA .p7m

See more Digital Signatures Examples

Demonstrates how to verify the signature and extract the XML from a FatturaPA .p7m file. Rust

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

let bd = chilkat::BinData::new();
if bd.load_file("qa_data/p7m/IT01879020517_abc.xml.p7m").is_err() {
    println!("Failed to load the .p7m file");
    return;
}

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

// Verify and extrct the payload contained within the .p7m.
// In this case, the payload is the FatturaPA XML.
// If successful, the resulting bd will contain only the XML.
if crypt.opaque_verify_bd(&bd).is_err() {
    println!("{}", crypt.last_error_text());
    println!("Failed to extract and verify.");
    return;
}

// Save the XML to a file.
let _ = bd.write_file("qa_output/zIT01879020517_abc.xml");

// Alternatively, load into an XML object and emit.
let xml = chilkat::Xml::new();
let _ = xml.load_xml(&bd.get_string("utf-8").unwrap_or_default());

println!("{}", xml.get_xml().unwrap_or_default());
