Load P7B and Iterate Certificates

See more PEM Examples

Demonstrates how to load a .p7b containing one or more certificates access each of them. Rust

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

let _ = false;

// The Chilkat PEM class was introduced in v9.5.0.49.  
// It requires the bundle to be unlocked, as shown above.
let pem = chilkat::Pem::new();

// Load the .p7b from a file.
if pem.load_p7b_file("../myCertFiles/myP7b.p7b").is_err() {
    println!("{}", pem.last_error_text());
    return;
}

// Note: If the app already has the p7b loaded in memory, the LoadP7b method
// may be called instead.  (see the online reference documentation)

// Iterate over the certificates.
let num_certs = pem.num_certs();
let mut i = 0;

while i < num_certs {

    let cert = pem.get_cert(i).unwrap();
    println!("Certificate {} : {}", i, cert.subject_dn());

    i = i + 1;
}
