+# OpenSSL 1.1 Test Shim
+
+These binaries (libcrypto.so.1.1 and libssl.so.1.1) are bundled for Mongo2Go-based integration tests so they can run on hosts that only provide OpenSSL 3.
+
+Source package: https://launchpad.net/ubuntu/+archive/primary/+files/libssl1.1_1.1.1f-1ubuntu2_amd64.deb
+
+Licensing follows the OpenSSL and SSLeay licenses that accompany the upstream package.
+
+## Usage
+
+1. Point `LD_LIBRARY_PATH` at this directory before running any test suite that spins up Mongo2Go:
+
+   ```bash
+   export LD_LIBRARY_PATH="$(git rev-parse --show-toplevel)/tests/native/openssl-1.1/linux-x64:${LD_LIBRARY_PATH:-}"
+   ```
+
+   The helper in `tests/shared/OpenSslLegacyShim.cs` will append the path automatically when the tests run, but exporting the variable up-front avoids surprises when using custom harnesses (e.g., `dotnet test` filters).
+
+2. Example one-shot command:
+
+   ```bash
+   LD_LIBRARY_PATH="$(pwd)/tests/native/openssl-1.1/linux-x64" \
+     dotnet test src/Excititor/__Tests/StellaOps.Excititor.Worker.Tests/StellaOps.Excititor.Worker.Tests.csproj --nologo
+   ```
+
+3. CI runners should add the same directory to their environment or place the binaries on a globally accessible library path.
