About:
Mbed TLS is an open source, portable, easy to use, readable and flexible TLS library. It provides a comprehensive set of cryptographic primitives, X.509 certificate handling, and the TLS protocol stack. Its modular design allows developers to include only the necessary components, making it ideal for embedded systems and constrained environments.

Key Features:

Implements TLS 1.2/1.3 and DTLS protocols
Comprehensive cryptographic primitives (AES, SHA, RSA, ECC)
X.509 certificate parsing and validation
Modular and portable design for embedded systems

Use Cases:

Securing IoT device communications
Implementing client-side HTTPS requests
Building custom TLS/SSL servers and clients

Alternatives:

openssl – OpenSSL is more feature-rich and ubiquitous but has a larger footprint and more complex API.
libressl – LibreSSL is a fork focusing on security and code cleanliness, primarily for BSD systems.
