    Data security for VB6 web-app

    When developing web-app with VB6, data exchange between the pc-clients and the web-server is done via XML or Json or binary data. I wonder if I need to encrypt these XML or Json or binary data before transferring them? What is the best way to the data security for vb6 web-apps? Any advice and suggestions would be greatly appreciated.

    While you might fiddle with encrypting payloads yourself, most effective encryption schemes are not practical to do in script at the client side.

    If you are really worried about data being spied on as it goes over the wire then your obvious answer is to use HTTPS instead of HTTP. While you are at it you probably want your server to support gzip and/or deflate compression.

    Hi dilettante, thanks for your reply, I need to learn how to convert http to https.

    Hi dreammanor. If you are using Nginx, here's how to configure it for SSL:

    Code:
    http://nginx.org/en/docs/http/configuring_https_servers.html
    You will need an SSL certificate of course - free ones are available from Let's Encrypt. You'll need to find a Windows client for issuing and renewing certificates through Let's Encrypt (I use Linux for this, so I can't recommend any particular clients unfortunately).
