micro-ecc
==========
A small and fast ECDH and ECDSA implementation for 8-bit, 32-bit, and 64-bit processors.
The static version of micro-ecc (ie, where the curve was selected at compile-time) can be found in the "static" branch.
Features
--------
* Resistant to known side-channel attacks.
* Written in C, with optional GCC inline assembly for AVR, ARM and Thumb platforms.
* Supports 8, 32, and 64-bit architectures.
* Small code size.
* No dynamic memory allocation.
* Support for 5 standard curves: secp160r1, secp192r1, secp224r1, secp256r1, and secp256k1.
* BSD 2-clause license.
Usage Notes
-----------
### Point Representation ###
Compressed points are represented in the standard format as defined in http://www.secg.org/sec1-v2.pdf; uncompressed points are represented in standard format, but without the `0x04` prefix. All functions except `uECC_decompress()` only accept uncompressed points; use `uECC_compress()` and `uECC_decompress()` to convert between compressed and uncompressed point representations.
Private keys are represented in the standard format.
### Using the Code ###
I recommend just copying (or symlink) the uECC files into your project. Then just `#include "uECC.h"` to use the micro-ecc functions.
For use with Arduino, you can use the Library Manager to download micro-ecc (**Sketch**=>**Include Library**=>**Manage Libraries**). You can then use uECC just like any other Arduino library (uECC should show up in the **Sketch**=>**Import Library** submenu).
See uECC.h for documentation for each function.
### Compilation Notes ###
* Should compile with any C/C++ compiler that supports stdint.h (this includes Visual Studio 2013).
* If you want to change the defaults for any of the uECC compile-time options (such as `uECC_OPTIMIZATION_LEVEL`), you must change them in your Makefile or similar so that uECC.c is compiled with the desired values (ie, compile uECC.c with `-DuECC_OPTIMIZATION_LEVEL=3` or whatever).
* When compiling for a Thumb-1 platform, you must use the `-fomit-frame-pointer` GCC option (this is enabled by default when compiling with `-O1` or higher).
* When compiling for an ARM/Thumb-2 platform with `uECC_OPTIMIZATION_LEVEL` >= 3, you must use the `-fomit-frame-pointer` GCC option (this is enabled by default when compiling with `-O1` or higher).
* When compiling for AVR, you must have optimizations enabled (compile with `-O1` or higher).
* When building for Windows, you will need to link in the `advapi32.lib` system library.

Setting a correctly functioning RNG function improves the resistance to side-channel attacks
for uECC_shared_secret() and uECC_sign_deterministic().
A correct RNG function is set by default when building for Windows, Linux, or OS X.

you can define uECC_POSIX to use the predefined RNG. For embedded platforms there is no predefined
