func chilkatTest() {
    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let crypt = CkoCrypt2()!

    // The output will be Hex, so set the EncodingMode:
    crypt.encodingMode = "hex"

    // Set the hash algorithm:
    // Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
    crypt.hashAlgorithm = "md5"

    var mac: String?

    // Set the HMAC key:
    crypt.setHmacKeyEncoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b", encoding: "hex")
    mac = crypt.hmacStringENC("Hi There")
    print("\(mac!)")

    crypt.setHmacKeyEncoded("Jefe", encoding: "ansi")
    mac = crypt.hmacStringENC("what do ya want for nothing?")
    print("\(mac!)")
