uECC_HashContext => const uECC_HashContext This is an important piece of "documentation" as it indicates to the caller that a uECC_HashContext can be initialized and subsequently used multiple times (for multiple signatures).
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.
Compressed points are represented in the standard format as defined in http://www.secg.org/collateral/sec1_final.pdf; uncompressed points are represented in standard format, but without the 0x04
prefix. All functions except uECC_compress()
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.
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 just create a symlink to the uECC
directory in your Arduino libraries
directory. 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.

), 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).-fomit-frame-pointer
