Merge pull request #60 from emargolis/master Added new API functions
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.
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).-fomit-frame-pointer

or higher).uECC_OPTIMIZATION_LEVEL
