Encrypt using Cert to produce -----BEGIN PKCS7----- ... -----END PKCS7-----

See more Encryption Examples

Demonstrates how to encrypt using a certificate to produce output such as:

-----BEGIN PKCS7-----
MIIHPwYJKoZIhvcNAQcEoIIHMDCCBywC ...
...
...
-----END PKCS7-----

The certificate to be used is not your own, but the certificate of the intended recipient of the message. Rust

let mut success = false;

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

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

// Specify the encryption to be used.
// "pki" indicates "Public Key Infrastructure" and will create a PKCS7 encrypted (enveloped) message.
crypt.set_crypt_algorithm("pki");
crypt.set_pkcs7_crypt_alg("aes");
crypt.set_key_length(128);
crypt.set_oaep_hash("sha256");
crypt.set_oaep_padding(true);

// A certificate is needed as the encryption key..
let cert = chilkat::Cert::new();
success = cert.load_from_file("qa_data/certs/testCert.pem").is_ok();
if !success {
    println!("{}", cert.last_error_text());
    return;
}

// Tell the crypt object to use the certificate.
let _ = crypt.set_encrypt_cert(&cert);

let to_be_encrypted = "This string is to be encrypted.".to_string();

// Get the result in multi-line BASE64 MIME format.
crypt.set_encoding_mode("base64_mime");

let encrypted_str = crypt.encrypt_string_enc(&to_be_encrypted).unwrap_or_default();
if !success {
    println!("{}", crypt.last_error_text());
    return;
}

// Make a "-----BEGIN PKCS7-----" ... "-----END PKCS7-----" sandwich...
let sb = chilkat::StringBuilder::new();
let _ = sb.append_line("-----BEGIN PKCS7-----", true);
let _ = sb.append(&encrypted_str);
let _ = sb.append_line("-----END PKCS7-----", true);

let out_str = sb.get_as_string().unwrap_or_default();

println!("{}", out_str);

// Sample output:

// -----BEGIN PKCS7-----
