Any llvm tool to sign binaries cross platformly?

Does llvm provide something like llvm-signtool to sign binaries? Many platforms are trying to tightening control over untrusted binaries for running. Does llvm provide a tool for that?

Also i want to see it get integrated with clang command line itself so that it can be integrated with traditional command line, is that possible?

clang++ -o hello.exe hello.cpp -O3 -fuse-signtool=llvm-signtool -fsigned-certificate=${CERTIFCATEPATH} -fuse-ld=lld

Start by reviewing the LLVM/Clang command-line entry points and the proposed llvm-signtool and lld integration described in the issue. Determine whether existing LLVM components support cross-platform binary signing and define the interfaces, supported platforms, certificate handling, and tests needed for a complete feature.
