Read JCEKS Containing Secret Keys

See more Java KeyStore (JKS) Examples

Demonstrates how to read a JCEKS keystore file containing symmetric secret keys (for AES, Blowfish, HMAC SHA25, ChaCha, etc.)

This example uses the jceks sample file that you may download from Sample JCEKS with Secret Keys

The file password is "filePassword". The password for each secret key contained in the JCEKS is "secret".

This example requires Chilkat v9.5.0.66 or greater.

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    // IMPORTANT: This example requires Chilkat v9.5.0.66 or greater.

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

    CkJavaKeyStore jceks = new CkJavaKeyStore();

    success = jceks.LoadFile("filePassword","qa_data/jks/secretKeys_filePassword.jceks");
    if (success != true) {
        System.out.println(jceks.lastErrorText());
        return;
        }

    String keyPassword = "secret";

    // Iterate over each secret key and get the key bytes and aliases..
    int i = 0;
    int numSecretKeys = jceks.get_NumSecretKeys();
    while (i < numSecretKeys) {

        System.out.println("---- Secret Key " + i);
        System.out.println("Alias: " + jceks.getSecretKeyAlias(i));
        // Get the secret key bytes in a desired encoding (base64, hex, base64url, etc.)
        System.out.println("Key Bytes (hex): " + jceks.getSecretKey(keyPassword,i,"hex"));
        System.out.println("Key Bytes (base64): " + jceks.getSecretKey(keyPassword,i,"base64"));

        i = i+1;
        }
