OpenSSL is an open-source implementation of the SSL (Secure Sockets Layer) and TLS (Transport Layer Security) protocols. OpenSSL also provides cryptography libraries for the secure communication between your application/browser and the server that hosts the services you are using.
Features and Technologies that Require OpenSSL
RAD Studio requires OpenSSL for HTTPS support for the following features and technologies:
- 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. You need to install the 32-bit or 64-bit OpenSSL depending on the EMS Server binary you are running.
- InterBase: InterBase uses OpenSSL for encryption and OTW/SSL features.
- 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.
If your application requires OpenSSL support, you need to have the necessary library files in your file system before deploying your application.
|Windows (32-bit and 64-bit)
|libeay32.dll and ssleay32.dll
|libcrypto.a and libssl.a
Review the requirements below depending on the platform that you are using:
32-bit and 64-bit Windows
To install OpenSSL on 32-bit or 64-bit Windows, you need to copy the libeay32.dll and ssleay32.dll dynamic library files to your file system, you can download them from one of these locations:
- Option 1 - Download the OpenSSL installer files and install them.
- Option 2 - Download the OpenSSL compressed library files and copy the libeay32.dll and ssleay32.dll files to your system path.
- If you go for Option 2 and decide to copy libeay32.dll and ssleay32.dll files to your system path, ensure you copy them to the right location:
- 32-bit Windows: You must copy the libeay32.dll and ssleay32.dll 32-bit files to your Windows system folder (System32 folder).
- 64-bit Windows: You must copy the libeay32.dll and ssleay32.dll 64-bit files to your Windows system folder for 64-bit files (System32) and the libeay32.dll and ssleay32.dll 32-bit files to your Windows 32-bit files folder (SysWOW64 folder).
- So when working with a 64-bit Windows, remember:
- System32 folder is for 64-bit files only.
- SysWOW64 folder is for 32-bit files only.
To install OpenSSL on 64-bit iOS device, you must copy the libcrypto.a and libssl.a SSL library files to your system. For the moment, there are no known safe and supported options to safely download iOS OpenSLL.
However, if you must and ONLY as a fallback solution, you can download the .zip iOS OpenSSL, then extract it and find the .a files in the
\lib directory. You must copy the libcrypto.a and libssl.a SSL library files to these directories:
C:\Program Files (x86)\Embarcadero\Studio\23.0\lib\iosDevice64\debug
C:\Program Files (x86)\Embarcadero\Studio\23.0\lib\iosDevice64\release
macOS and Android
No additional steps are required in macOS since the required files are already in your file system.
