fleaTLS is a software library that enables flexible and lightweight TLS and cryptography for resource constrained devices. fleaTLS is both available under free-of-charge and commercial licensing.
fleaTLS has a small RAM and code footprint.
Thorough security design, implementation and testing.
High performance on resource constrained devices through optimized implementations.
The library is written in portable C99 code and and runs efficiently on any 16- or 32-bit architecture.
A wide range of compile-time configuration options for the optimization of security and performance.
Supports heap usage and a real stack-only mode.
Free usage in open-source projects under GPL, free usage in closed-source projects under the flea licence or commercial licensing.
