Examine the Contents of a .p7m by Converting to XML

Examines the contents of a .p7m signature by converting it to XML. Rust

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

let asn = chilkat::Asn::new();

if asn.load_binary_file("qa_data/p7m/a.p7m").is_err() {
    println!("{}", asn.last_error_text());
    return;
}

// Convert to XML.
let str_xml = asn.asn_to_xml().unwrap_or_default();

// The XML returned by AsnToXml will be compact.
// To get the XML indented in human-readable form, load
// into the Chilkat XML object and emit..
let xml = chilkat::Xml::new();
let _ = xml.load_xml(&str_xml);

println!("{}", xml.get_xml().unwrap_or_default());
let _ = xml.save_xml("qa_output/a.xml");
