zip iOS OpenSSL, extract it and find the. To install OpenSSL in a 32-bit or 64-bit iOS device, you must copy the libcrypto.a and libssl.a SSL library files to your system. SysWOW64 folder is for 32-bit files only.System32 folder is for 64-bit files only.So when working with a 64-bit Windows, remember: 64-bit Windows: You must copy the libea圓2.dll and sslea圓2.dll 64-bit files to your Windows system folder for 64-bit files (System32) and the libea圓2.dll and sslea圓2.dll 32-bit files to your Windows 32-bit files folder (SysWOW64 folder).32-bit Windows: You must copy the libea圓2.dll and sslea圓2.dll 32-bit files to your Windows system folder (System32 folder).If you go for Option 2 and decide to copy libea圓2.dll and sslea圓2.dll files to your system path, ensure you copy them to the right location: Option 2 - Download the OpenSSL compressed library files and copy the libea圓2.dll and sslea圓2.dll files to your system path.Option 1 - Download the OpenSSL installer files and install them.To install OpenSSL in a 32-bit or 64-bit Windows, you need to copy the libea圓2.dll and sslea圓2.dll dynamic library files to your file system, you can download them from one of these locations: Review the requirements below depending on the platform that you are using: If your application requires OpenSSL support, you need to have the necessary library files in your file system before deploying your application. DataSnap Server: OpenSSL is required by DataSnap servers when encryption filters are enabled, or when the Communication Protocol is set to HTTPS in the DataSnap Server Wizard.InterBase: InterBase uses OpenSSL for encryption and OTW/SSL features.You need to install the 32-bit or 64-bit OpenSSL depending on the EMS Server binary you are running. Sending push notifications with the EMS Server: You need to install the OpenSSL libraries in the system where the RAD Server Engine (EMS Server) runs to send push notifications.RAD Studio requires OpenSSL for HTTPS support for the following features and technologies: 1 Features and Technologies that Require OpenSSLįeatures and Technologies that Require OpenSSL.This calls the DLL directly through the Win API.

Fill in the code in the library as given below.

Start a new DLL project in Delphi (Click File −> New, select DLL).

The following code creates a DLL containing two functions, Min and Max, with the objective of returning the larger of two integers.
