Extract a File from a .p7m (PKCS7 Signed-Data)

See more Encryption 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. It can be verified and restored by calling VerifyP7M. Rust

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

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

// What is a .p7m file?

let output_file = "/Users/chilkat/testData/pdf/sample.pdf".to_string();
let in_file = "/Users/chilkat/testData/p7m/sample.pdf.p7m".to_string();

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

println!("Success!");
