mbed TLS: Compact, Fast, and Flexible Open Source Cryptographic Library
mbed TLS is an open source cryptographic library that provides TLS and SSL capabilities for embedded devices. It is designed to be compact, fast, and flexible enough for both small and large embedded systems.
What is Mbed TLS?
mbed TLS, formerly known as PolarSSL, is an open source cryptographic and TLS/SSL library designed specifically for small, resource-constrained devices. It aims to make it easy for developers to deploy and use robust security features in embedded products such as smart meters, wearables, IoT devices, routers, and more.
Some key features of mbed TLS include:
- Support for SSLv3, TLS1.0, TLS1.1, and TLS1.2 communication protocols
- Variety of cryptographic algorithms including symmetric ciphers, public key cryptography, hashes, message authentication codes, and key derivation functions
- Lightweight and modular architecture making it suitable for devices with very limited CPU and memory resources
- Extensive OS and platform support including ThreadX, FreeRTOS, Windows, Linux, etc.
- APIs in C designed for easy integration and optimum performance
- Permissive Apache 2.0 and GPL 2.0 licensing
Overall, mbed TLS aims to give embedded developers an easy way to build security, cryptography, and TLS capabilities into their resource-constrained devices and applications.
