Load an RSA public key from a hex modulus and exponent. Rust

// Load a 128-byte (1024-bit) modulus + exponent into a Chilkat public key object..
let modulus = "BF5F4AF9A018B5F324A0C10448C0D3248D9BE78967FDC551A27876AC5789ADCBA8245D3D942AE3799563D895DA801E765D225A54FA15DAB2C4731DD817DCF94A9AD62197074C2349442093A206234BF3747F0E88AA6F538355684CC1FB26FCE029C9050A1DAF9F507C2BABF6EFC9FB16320C8036721BE0279FBB76122C41E429".to_string();

let exponent = "00000003".to_string();

// We'll need to re-encode from hex to base64..
let bd_modulus = chilkat::BinData::new();
let _ = bd_modulus.append_encoded(&modulus, "hex");
let bd_exponent = chilkat::BinData::new();
let _ = bd_exponent.append_encoded(&exponent, "hex");

let xml = chilkat::Xml::new();
xml.set_tag("RsaKeyValue");
xml.new_child2("Modulus", &bd_modulus.get_encoded("base64").unwrap_or_default());
xml.new_child2("Exponent", &bd_exponent.get_encoded("base64").unwrap_or_default());

// Now load into the pubkey object..
let pubkey = chilkat::PublicKey::new();
if pubkey.load_from_string(&xml.get_xml().unwrap_or_default()).is_err() {
    println!("{}", pubkey.last_error_text());
    return;

println!("Success.");
