 * 🔝[liblithium](https://github.com/teslamotors/liblithium) - Lightweight cryptography library that is portable by design. It requires only standard C99 and does not assume 8-bit addressability, making it suitable for use on some DSP architectures as well as mainstream architectures.
 * 🔝[trezor-crypto](https://github.com/trezor/trezor-firmware/tree/master/crypto) - Heavily optimized cryptography algorithms for embedded Devices.
