(C# UWP/WinRT) Get the Certificate with Private Key from a Java KeyStore

See more Java KeyStore (JKS) Examples

Load a Chilkat certificate object from a Java KeyStore.

Chilkat for the Universal Windows Platform (UWP)

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

// Most of the time a .jks contains one certificate with it's associated private key.
// (Similar to how a .pfx/.p12 usually contains a particular certificate with private key.)
// This example demonstrates how to get the certificate with private key such that it can be used
// by other Chilkat classes wherever a cert w/ private key is needed.
Chilkat.JavaKeyStore jks = new Chilkat.JavaKeyStore();
string password = "secret";
bool success = jks.LoadFile(password,"qa_data/jks/test_secret.jks");
if (success != true) {
    Debug.WriteLine(jks.LastErrorText);
    return;
}

// Make sure we have a private key.
if (jks.NumPrivateKeys < 1) {
    Debug.WriteLine("No private key available.");
    return;
}

// -------------------------------------------------------------------------
// Get the certificate chain associated with the 1st (and probably only) private key in the JKS.
Chilkat.CertChain chain = jks.GetCertChain(0);
if (jks.LastMethodSuccess != true) {
    Debug.WriteLine(jks.LastErrorText);
    return;
}

Chilkat.Cert cert = chain.GetCert(0);
if (chain.LastMethodSuccess != true) {
    Debug.WriteLine(chain.LastErrorText);

    return;
}

// Verify again that this cert has a private key.
if (cert.HasPrivateKey() != true) {
    Debug.WriteLine("Certificate has no associated private key.");

    return;
}

// We now have the cert object with it's associated private key, and it can be used in other Chilkat classes where needed.
// For example..

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();
success = crypt.SetSigningCert(cert);
if (success == false) {
    Debug.WriteLine(crypt.LastErrorText);
    return;
}

// ...
// ...
