Add ECDSA test for Arduino
A small and fast ECDH and ECDSA implementation for 8-bit, 32-bit, and 64-bit processors.
The old version of micro-ecc can be found in the “old” 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. uECC_make_key()
, uECC_shared_secret()
, uECC_sign()
, and uECC_verify()
only handle uncompressed points; you can 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) uECC.h, uECC.c, and the appropriate asm_<arch>_.inc (if any) into your project. Then just #include "uECC.h"
to use the micro-ecc functions.
See uECC.h for documentation for each function.
uECC_ASM
is defined to uECC_asm_small
or uECC_asm_fast
), 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.
