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 crypt = CkoCrypt2()!

    // What is a .p7m file?

    var outputFile: String? = "/Users/chilkat/testData/pdf/sample.pdf"
    var inFile: String? = "/Users/chilkat/testData/p7m/sample.pdf.p7m"

    // Verify and restore the original file:
    success = crypt.verifyP7M(p7mPath: inFile, destPath: outputFile)
    if success == false {
        print("\(crypt.lastErrorText!)")
        return
