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

func chilkatTest() {
    var success: Bool = false

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

    let pem = CkoPem()!

    // Load the PEM from a file.
    // If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
    var password: String? = "myPassword"
    success = pem.loadFile("../myPemFiles/myPem.pem", password: password)
    if success == false {
        print("\(pem.lastErrorText!)")

    // Note: If the app already has the PEM pre-loaded in a string variable, then load it 
    // by calling LoadPem instead.  
    var pemContent: String? = "... the PEM contents ..."
    success = pem.load(pemContent, password: password)
    // Check for success as before..

    // Convert to a JavaKeyStore object.
    // The alias, if a non-empty string, will be applied to the 1st private key or 
    // certificate.  All other keys and/or certificates will be assigned an auto-generated
    // alias.
    var alias: String? = "anything_I_want_here"

    // This is the passord that will be required to access the created JKS.
    var jksPassword: String? = "myJksSecret"
    let jks = CkoJavaKeyStore()!

        return
    }

    // Save the JKS to a file.  The password passed here is used for the keyed hash of the
    // entire JKS file.  This may be different (if desired) than the password for individual private keys
    // contained within the JKS.
