.NET Core 2.1 SDK Linux x64 No usable version of the libssl was found

Question

I have downloaded the dotnet-core binary SDK packet (dotnet-sdk-2.1.400-linux-x64.tar.gz) and want to install it on my void-linux system which uses LibreSSL. After i run dotnet help i got the response No usable version of the libssl was found and the execution gets aborted.

Would it be possible to get the SDK running with LibreSSL or what version of the libssl is needed? I couldn't figure out to what ssl-library dotnet is linked.

LibreSSL is not supported at all by .NET Core.

.NET Core needs to use OpenSSL version 1.0. It does not even support OpenSSL 1.1 (which is API and ABI incompatible with OpenSSL 1.0). Edit 2021: Recent versions of .NET Core and .NET >= 5 support OpenSSL 1.1 now. Support for OpenSSL 3.0 is planned too.

.NET Core is actually looking (via dlopen) for lots of permutations of files that would match paths like /usr/lib(64)/libssl.so.*.
