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

    let crypt = CkoCrypt2()!

    // Here are some bytes as a hex string
    var hex: String? = "4142434445462140232425"

    // The ReEncode method converts a string from one encoding to another.
    // Valid encodings are "url", "base64", "qp", "hex", "modbase64", "base64url", "base32", "base58",
    // and any of the encodings listed here:  http://cknotes.com/chilkat-binary-encoding-list

    // Convert from hex to base64
    var b64: String? = crypt.reEncode(hex, fromEncoding: "hex", toEncoding: "base64")
    print("base64: \(b64!)")

    // Convert from base64 to base32
    var b32: String? = crypt.reEncode(b64, fromEncoding: "base64", toEncoding: "base32")
    print("base32: \(b32!)")

    // Convert from base32 back to hex
    hex = crypt.reEncode(b32, fromEncoding: "base32", toEncoding: "hex")
    print("hex: \(hex!)")
