有的，SDK的159的版本app.h会有appm_use_aes128_decryption函数可以进行aes128的解密。 demo_basci_function工程中user_proj_main()入口函数有示例代码。 如下：
void get_aes128_decryption(void *arg)
{
struct gapm_use_enc_block_ind *param = (struct gapm_use_enc_block_ind *)arg;
printf("get_aes128_decryption: ");
show_reg2(param->result,KEY_LEN,1);
printf("\r\n");
}
void get_aes128_rst(void *arg)
{
struct gapm_use_enc_block_ind *param = (struct gapm_use_enc_block_ind *)arg;
printf("aes128: ");
show_reg2(param->result,KEY_LEN,1);
printf("\r\n");
uint8_t key[] = "0000000000000000";
appm_use_aes128_decryption(key,param->result,get_aes128_decryption);
}
void user_proj_main(void)
{
uint8_t plaintext[] = "0000000000000001";
uint8_t key[] = "0000000000000000";
appm_use_aes128_block(key,plaintext,get_aes128_rst);
}
