(Swift 2) 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.

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

    let jks = CkoJavaKeyStore()

    // 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.
    var success: Bool = jks.LoadFile("jksFilePassword", path: "/someDir/keyStore.jks")
    if success != true {
        print("\(jks.LastErrorText)")
        return
    }

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

    var cert: CkoCert?
    var alias: String?

    var i: Int

    // For each trusted certificate, access it by getting
    // it as a cert object.  Also get the alias associated with the certificate.
    print("Trusted Certs:")
    i = 0
    while i < numTrustedCerts {
        cert = jks.GetTrustedCert(i)
        print("\(jks.GetTrustedCertAlias(i)): \(cert!.SubjectDN)")
        cert = nil
        i = i + 1
    }

    var privKey: CkoPrivateKey?
    var certChain: CkoCertChain?

    // 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.
    print("Private Keys:")
    i = 0
    while i < numPrivateKeys {
        privKey = jks.GetPrivateKey("jksFilePassword", index: i)
        print("\(jks.GetPrivateKeyAlias(i))")
        certChain = jks.GetCertChain(i)

        // The 1st certificate in the chain is the one associated with the private key.
        cert = certChain!.GetCert(0)
        print("\(cert!.SubjectDN)")

        cert = nil
