+# KMSChain for C++
+
+We provide "Encryption & Key Management" service in operation with open sourced libraries with support for Javascript, Python, Go, Rust, Java, C++ languages.
+
+Our goal is to enable developers to build ’privacy by design’, end-to-end secured applications, without any technical complexities.
+
+This C++ library is our main low level algorithmic implementation, which is embedded in all our other SDK libraries and web services.
+
+# C Interface
+Most of the programming languages and low level API's don't have C++ integration capability, so for being platform and programing
+language agnostic, we are providing low level C interface for using KMSChain's encryption on any platform and with any programming language.
+
+[`inculde/CryptoMagic_C.h`](inculde/CryptoMagic_C.h) is a single header file which contains all our API functions for having fully functional
+proxy re-encryption and key management system for your application.
+
+```cpp
+#include "CryptoMagic_C.h"
+....
+....
+cryptomagic_init();
+void * cm = cryptomagic_new();
+.....
+.....
+cryptomagic_clean(cm);
+```  
+As a low level interface, we are providing memory allocation and de-allocation functions for each object.
+
+# Building
+For building project as a static library, you will need to `install OpenSSL`, because currently we are using OpenSSL as a cryptographic backend.
+```bash
+mkdir build
+cd build && cmake ..
+make
+```
