Rust Requires Chilkat v11.0.0+

RSA Decrypt using PEM

See more RSA Examples

This example demonstrates decryping RSA encrypted data that is base64 encoded. It uses a private key loaded from a PEM file. Rust

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

let rsa = chilkat::Rsa::new();

let key = chilkat::PrivateKey::new();

// Load an RSA private key from an unencrypted PEM file:
// (To load from an encrypted PEM file, call LoadEncryptedPemFile instead.)

if key.load_pem_file("qa_data/rsa/decryptTest/priv.pem").is_err() {
    println!("{}", key.last_error_text());
    return;
}

// Make the key available to the RSA object
if rsa.use_private_key(&key).is_err() {
    println!("{}", rsa.last_error_text());
    return;
}
