# CTEST_TLS_VERSION

Added in version 3.30.

Specify the CTest `TLSVersion` setting in a `ctest(1)` Dashboard Client script or in project `CMakeLists.txt` code before including the `CTest` module. The value is a minimum TLS version allowed when submitting to a dashboard via `https://` URLs.

The value may be one of:

- `1.0`

- `1.1`

- `1.2`

- `1.3`

If `CTEST_TLS_VERSION` is not set, the `CMAKE_TLS_VERSION` variable or `CMAKE_TLS_VERSION` environment variable is used instead.
