  • for macOS and Windows, all versions of the Solace .NET API
  • for Linux, versions 10.24 and earlier of the Solace .NET API

Transport Layer Security (TLS) provides secure connections between Solace Messaging APIs and event brokers. The Solace .NET API supports the following TLS versions. The recommended version to use is the most recent version of TLS:

The Solace .NET API now supports TLS 1.3 connections when connecting to event brokers that request TLS 1.3, allowing you to prepare your client applications in advance. Full end-to-end testing capabilities will be enabled with the upcoming event broker release 10.25.0, planned for June 2025. For more information, see Support Dates for Release Versions. After 10.25.0 is available, you can then perform end-to-end testing and deployment of TLS 1.3.

  • TLS 1.2
  • TLS 1.3—Requires version 10.28 or later of the Solace .NET API.

When the term TLS/SSL is used in this documentation, we are referring to these forms of data encryption. We don't recommend that you use SSL unless it's required for backwards compatibility.
