(JavaScript) Load Java KeyStore and Access Contents

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.

Note: This example requires Chilkat v11.0.0 or greater.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var jks = new CkJavaKeyStore();

// 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.
success = jks.LoadFile("jksFilePassword","/someDir/keyStore.jks");
if (success == false) {
    console.log(jks.LastErrorText);
    return;
}

// Find out how many of each type of entry:
var numTrustedCerts = jks.NumTrustedCerts;
var numPrivateKeys = jks.NumPrivateKeys;

var cert = new CkCert();
var alias;

// For each trusted certificate, access it by getting
// it as a cert object.  Also get the alias associated with the certificate.
console.log("Trusted Certs:");
var i = 0;
while (i < numTrustedCerts) {
    success = jks.TrustedCertAt(i,cert);
    console.log(jks.GetTrustedCertAlias(i) + ": " + cert.SubjectDN);
    i = i+1;
}

var privKey = new CkPrivateKey();
var certChain = new CkCertChain();

// 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.
console.log("Private Keys:");
i = 0;
while (i < numPrivateKeys) {
    jks.PrivateKeyAt("jksFilePassword",i,privKey);
    console.log(jks.GetPrivateKeyAlias(i));
    jks.CertChainAt(i,certChain);

    // The 1st certificate in the chain is the one associated with the private key.
    certChain.CertAt(0,cert);
    console.log(cert.SubjectDN);

    i = i+1;
