TLS 1.2 request to a TLS 1.0 webservice

Hi,

We changed our software so we now use TLS 1.2 in our communication with webservices. Suppose we do a request to a webservice that only accept TLS 1.0. Is that a problem given that we now use TLS 1.2? Or does it work in all the situations the request is at least of the same version as the webservice to be requested?

Regards,

Arne

Yes it will be a problem. In order for the clients to support TLS 1.2 the user should enable the check box in the internet explorer settings from the advanced tab. Please refer to the screen shot for your reference.

It only depends on your Customer's ability to work with this protocol in their browsers.
I'd suggest to check with them by doing a test before going live.

I will further specify my question. The situation is that we have software that is installed on a server. From this server we can do requests to another server where a webservice is hosted. Suppose that this hosted webservice only supports TLS 1.0. Does that give any problems? I asked this for compatibility reasons. We want to be sure that a new version of our software doesn't kill existing connections.

Thank you for rephrasing it.. Yes as you said there will be compatibility issue. I have personally worked on exactly the same scenario and it did not work out. I had to roll back the settings to support TLS 1.0

You can try using a tool IISCrypto in your test environment to understand much better on the same if you need hands on experience

Thanks Ashvin. But is it possible to both be able to do TLS 1.0 requests and TLS 1.2 requests? And do you know an online exposed webservice that only accepts TLS 1.0 (for testing purposes)?

Yes, What you have put through now is possible but both the hosted server and your Crypto server should accept the request for both TLS 1.0 and 1.2

You can test your TLS validation from " https://www.ssllabs.com/ssltest " but not sure about exposed public sites
