cross socket ssl动态库

cross socket ssl动态库

cross socket支持ssl需要动态库的支持，它的源码注释就说得很清楚。

unit Net.OpenSSL;

{
  OpenSSL 下载:
  https://indy.fulgan.com/SSL/
  https://github.com/leenjewel/openssl_for_ios_and_android

  OpenSSL iOS静态库下载:
  https://indy.fulgan.com/SSL/OpenSSLStaticLibs.7z

  LibreSSL 下载:
  http://ftp.openbsd.org/pub/OpenBSD/LibreSSL/

  Linux下需要安装libssl开发包
  sudo apt-get install libssl-dev
}

// 使用 LibreSSL
// LibreSSL 是 OpenSSL 的一个分支, 由 OpenBSD 维护, 接口与 OpenSSL 兼容
// 目前(2.4.2) 执行效率比 OpenSSL(1.0.2h) 低
{.$DEFINE __LIBRE_SSL__}

// iOS真机必须用openssl的静态库
{$IF defined(IOS) and defined(CPUARM)}
  {$DEFINE __SSL_STATIC__}
{$ENDIF}
