Merge pull request #191 from gridware/a-house-divided-cannot-stand asm_arm.inc: use RESUME_SYNTAX everywhere
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.
