尝试最新版本的OpenSSL.NET（ 0.4.1 ），现在应该包括静态链接到CRT的预建的libeay32.dll和ssleay32.dll二进制文件。或者，您可以自己构建这些库或使用openssl.org中的官方构建。

Try the latest version of OpenSSL.NET (0.4.1) which should now include prebuilt libeay32.dll and ssleay32.dll binaries that link to the CRT statically. Alternatively, you can build these libraries yourself or use an 'official' build from openssl.org.
