Revert a TLS Connection to Plain TCP

See more Socket/SSL/TLS Examples

Demonstrates Socket.ConvertFromSsl, which ends the TLS layer while leaving the underlying TCP connection open for subsequent unencrypted communication.

func chilkatTest() {
    var success: Bool = false

    let socket = CkoSocket()!

    //  Connect to the server using TLS.
    var bTls: Bool = true
    var maxWaitMs: Int = 5000
    success = socket.connect(hostname: "example.com", port: 5000, ssl: bTls, maxWaitMs: maxWaitMs)
    if success == false {
        print("\(socket.lastErrorText!)")
        return
    }

    //  End the TLS layer while keeping the underlying TCP connection open for subsequent unencrypted
    //  communication.  This is the reverse of a STARTTLS-style upgrade and is valid only while TLS is
    //  active.
    success = socket.convertFromSsl()
    if success == false {
        print("\(socket.lastErrorText!)")
        return
    }

    print("Reverted to a plain TCP connection.")
