1. The project began in SHA256_embedded's sha256 files.
2. I only ported to embedded chips, such as Intel 8051 series CPUs.
3. Supported compilers are:
   1. GCC ANSI, C89, C9X, C1X
   2. Keil CX51.

run

1. git clone [email protected]:iroan/sha256-8051cpu.git
2. cd sha256-8051cpu && make

usage

1. #include "sha256.h"
2. add code:

   sha256_init(&ctx);
   sha256_update(&ctx, msg, msglen);
   sha256_final(&ctx, result);

3. compile project with sha256.c
