C++ (Cpp) sm4_setkey Examples

Example #1

File: sm4.c Project: LiTianjue/work-proj

/*
 * SM4 key schedule (128-bit, decryption)
 */
void sm4_setkey_dec( sm4_context *ctx, unsigned char key[16] )
{
    int i;
	ctx->mode = SM4_ENCRYPT;
    sm4_setkey( ctx->sk, key );
    for( i = 0; i < 16; i ++ )
    {
        SWAP( ctx->sk[ i ], ctx->sk[ 31-i] );
    }
}

Example #2

File: test.c Project: odzhan/tinycrypt

int main(void)
{
  sm4_ctx  c;
  //uint32_t i;
  int      equ;
  
  sm4_setkey(&c, tv_key, SM4_ENCRYPT);
  
  //for (i=0; i<1000000; i++) {
    sm4_encrypt(&c, tv_plain);
  //}
  
  equ = memcmp(tv_cipher, tv_plain, 16)==0;
  printf ("SM4 Test %s\n", equ ? "succeeded" : "failed");
  
  return 0;
}

Example #3

{
