DVA/Medicare Claiming PRODA Update of TLS for Dental4Windows

DVA/Medicare Claiming PRODA Update of TLS for Dental4Windows

Quote
Transport Layer Security (TLS) is a cryptographic protocol designed to provide security over a computer network and the internet.
Services Australia’s systems (DVA/Medicare Claiming) use TLS to secure online transactions between healthcare organisations and professionals, and Services Australia.
The Australian Signals Directorate provided advice outlining the TLS standards Services Australia must be compliant with and advised to cease using TLS version 1.0 and 1.1.

Important Information

Warning
The Services Australia systems will be upgraded to TLS 1.2 and TLS 1.3 on Tuesday 3 February 2026 at 8PM (AEDT) 
  1. This affects those clinics that use D4W in Australia and use D4W for DVA interacting with PRODA.
  2. Sites using our current release who attempt to interact with PRODA after this time will encounter an error. 
  3. The cut over dates will be a hard cut over. 
  4. Not taking action will reduce system availability.

Action Required Summary

Before the 3rd of February 2026 you will need to update (replace) some DLL files that D4W uses to communicate with Services Australia.
We have prepared new DLLs, and you can use them to replace the current ones without requiring any D4W build updates
After replacing these files: 
  • On PCs that have the DLLs registered, nothing further will be required.
  • On those PCs where the files have not previously been registered, the usual DVA registration will need to be done.
