ECC-secp256k1-ARM-64-bit-assembly

Implementation of finite field arithmetic and elliptic curve cryptography on the secp256k1 curve in ARM 64-bit assembly.

For better readability of the source code

• aliases are used for all registers -> see file 'aliases'.
• macros encapsulate frequently recurring commands and boilerplate for function declaration -> see files 'commonmacros' and 'u256macros'

C-interface for all public assembly functions: secp256k1.h

Unit tests: see tests.c
