The Mbed TLS library provides a set of cryptographic components that you can use and compile separately, and include or exclude?using a single configuration header file. Mbed TLS also provides a central SSL/TLS module that builds on the cryptographic components, the abstraction layers and the support components to provide a complete protocol implementation for SSL and TLS.

From a functional perspective, the library is split into three major parts:

• The SSL/TLS protocol implementation.
• A cryptographic library.
• An X.509 Certificate handling library.
