TLS TCP/IP HL7

[Jerry Sawa]

We currently have an interface with an offsite vendor where we connect via a VPN.  Vendor wants us to change from using a VPN to use TLS.

Received the following from the vendor if that makes anything clearer.

All existing customers are being transferred to the Azure Cloud and converted to TLS connectivity. The standard connection protocol in the Azure Cloud for interfaces is TLS (Transport Layer Security). This encryption protocol was chosen based on widespread compatibility and ease of implementation.

Not sure how to set this up, what documentation I could find is a little confusing.

We’re on 2022.09.03.01.  We do have the necessary license.

I’ll be attaching screenshots.

Any help would be greatly appreciated!!!!

I would put the URL in the “Host:” field?  See “PDF TCPIP Properties” attachment.

Not sure what to enter in the fields in the “CA Path  CA File” attachment.

I would try to find out if they’re using HTTPS or HL7 MLLP+TLS. HTTPS is more common.

They should send you a lot more information than you’ve provided here: protocol, server address, port, authentication type, TLS version, etc.

They did.  Sorry, I neglected to include.

The mode can be ClientAuth,

SSl Protocol — TLS 1.3.   

Cipher list — TLS_AES_128_GCM_SHA256.

In ‘SSL Configure’ choose Mode ‘ClientAnon’ so all paths are greyed out. You can then choose SSL Protocl ‘TLSv1.3’ (you need CL2022.09 for this; CL19.1 only supports up to TLSv1.2) and then select the required SSL Cipher Suite.

We are getting questions about secure/encrypted HL7 connections for all vendors. I don’t think many vendors can support this though.
