Subject: [PATCH] Remove unnecessary libssl dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This module performs RSA operations using libcrypto only — no TLS
functions from libssl are called. Remove the unused #include
<openssl/ssl.h> from RSA.xs, drop -lssl from the Unix link flags in
Makefile.PL, and update the Windows hints to query/link only libcrypto.

This reduces build dependencies, allowing the module to compile in
environments where only libcrypto headers and libraries are installed.
