[micro-ecc] Fix test and build errors The merge to the upstream code introduced some new changes to the test that throw compilation warnings. Fixed them and additionally added elftest runner as a dependency for the v2 unittest. Bug: 86669 Test: fx test micro-ecc-tests Change-Id: Ibac9e5e0b7bdf63b1042277f70006dd2ae1e6cfd Reviewed-on: https://fuchsia-review.googlesource.com/c/third_party/github.com/kmackay/micro-ecc/+/595455 Reviewed-by: Sundarajan Srinivasan <sundarsrini@google.com> Reviewed-by: Marco Vanotti <mvanotti@google.com>
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/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.
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.
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 GCC option (this is enabled by default when compiling with -O1 or higher).uECC_OPTIMIZATION_LEVEL >= 3, you must use the -fomit-frame-pointer GCC option (this is enabled by default when compiling with -O1 or higher).-O1 or higher).advapi32.lib system library.
