+# OpenSSL Build Dependencies
+
+Since this library is build against OpenSSL to use hashing algorithms within the Cython-based blockchain the necessary build dependencies for OpenSSL must be provided and placed in the corresponding folders.
+
+
+**Windows-only:** This package is currently only tested on Windows and therefore relies on the build process for this platform. The build process uses ***dynamic linking***.
+
+A distribution for Windows can be obtained from [https://slproweb.com/products/Win32OpenSSL.html](https://slproweb.com/products/Win32OpenSSL.html). The full installer is needed because only this kind of distribution includes all library files to build against.
+
+*2025-12-18: The current version used is 3.5.X which is the current LTS branch of OpenSSL*
+
+Copy the headers from the folder "include" and the build libs from "lib" of the installed OpenSSL distribution over to this directory structure into their corresponding folders. As of 2025/12, the dynamic libraries are located within a folder named "MD" which contains the files for dynamic linking.
+
+*Additionally, you need to copy the pre-compiled dynamic link library files (DLL) for "libcrypto" and "libssl". These must be placed in the source directory because they are shipped as part of the package distribution.*
