Rust Requires Chilkat v11.0.0+

Load Java KeyStore and Access Contents

See more Java KeyStore (JKS) Examples

Loads a Java keystore file and iterates over the contents. A Java keystore (.jks) file can contain one or more trusted root certificate entries and/or one or more private key entries. Each private key entry includes an associated certificate chain. Rust

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

let jks = chilkat::JavaKeyStore::new();

// Load the Java keystore from a file.  The JKS file password is used
// to verify the keyed digest that is found at the very end of the keystore.
// It verifies there has been no tampering with the file.
if jks.load_file("jksFilePassword", "/someDir/keyStore.jks").is_err() {
    println!("{}", jks.last_error_text());
    return;
}

// Find out how many of each type of entry:
let num_trusted_certs = jks.num_trusted_certs();
let num_private_keys = jks.num_private_keys();

let cert = chilkat::Cert::new();

// For each trusted certificate, access it by getting
// it as a cert object.  Also get the alias associated with the certificate.
println!("Trusted Certs:");
let mut i = 0;
while i < num_trusted_certs {
    let _ = jks.trusted_cert_at(i, &cert).is_ok();
    println!("{}: {}", jks.get_trusted_cert_alias(i).unwrap_or_default(), cert.subject_dn());
    i = i + 1;
}

let priv_key = chilkat::PrivateKey::new();
let cert_chain = chilkat::CertChain::new();

// For each private key entry, get the private key and
// the associated certificate chain.
// Each private key is password protected.  Usually it is the same
// password as used for the keyed digest of the entire JKS.  
// However, this does not have to be.  The password is passed
// here to handle the possibility of each private key requiring
// a different password.
println!("Private Keys:");
i = 0;
while i < num_private_keys {
    let _ = jks.private_key_at("jksFilePassword", i, &priv_key);
    println!("{}", jks.get_private_key_alias(i).unwrap_or_default());
    let _ = jks.cert_chain_at(i, &cert_chain);

    // The 1st certificate in the chain is the one associated with the private key.
    let _ = cert_chain.cert_at(0, &cert);
    println!("{}", cert.subject_dn());
