MicroECDSA
==========
Heavily optimized ECDSA (secp256k1) signer for embedded devices.
Distibuted under MIT License.
Notes
-----
a) the signer only understands secp256k1 elliptic curve
b) random generator in rand.c is using stdlib's rand() function.
you should replace this code with one that uses a hardware random
generator of your microcontroller in production.
(see speed-stm32/rand.c for such example)
