    Description

      Peer certificate verification on Windows via OpenSSL always fails unless a CA file or CA path was specified:

      Error (2026): TLS/SSL error: unable to get local issuer certificate

      Unlike *nix systems, system CAs are not stored in the file system (like /etc/ssl), but in the Windows registry. Since OpenSSL does not install certificates on Windows, the Windows CA store should be imported if no CA file or CA path was explicitly specified.
