使用aes_inf.h头文件里的aes128_ecb_decode_raw解密接口解密错误,解密出来的数据不对,麻烦帮忙看下同样的数据,加密成功了,用同一个Key就解密不出来,以下为代码片段

Code: Select all

BYTE_T data1[] ="b4046667e3c549673aa75369b605f342";
		BYTE_T datakey1[] ="6r4mq0ptoan2wf70";
		//UINT32_T outlen1 = 0;
		BYTE_T  outdata1[33] = {0};

	aes128_ecb_decode_raw(data1, strlen(data1), outdata1, datakey1);

		TAL_PR_INFO("data1;%s", data1);
		TAL_PR_INFO("strlen(data1);%d", strlen(data1));
		TAL_PR_INFO("outdata1;%s", outdata1);
		TAL_PR_INFO("strlen(outdata1);%d", strlen(outdata1));
		TAL_PR_INFO("datakey1;%s", datakey1);
	TAL_PR_DEBUG("AES_DE2: ");
        memset(dataget,0,32);
	for (int j = 0; j < strlen(outdata1); j++) {
        memset(cat,0,8);
        sprintf(cat,"%02x",outdata1[j]);
        strcat(dataget,cat);
	}
		TAL_PR_INFO("dedataget;%s", dataget);
	aes_free_data(outdata1);

以下为日志内容

解密接口没有什么问题，具体示例请参考如下：

Code: Select all

	
    BYTE_T key[] ="6r4mq0ptoan2wf70";
    BYTE_T plaintext[] ="l8hpkkjnn93mx0pe";
    BYTE_T ciphertext[32] ;
    BYTE_T decodetext[32] ;
    UINT_T i = 0;

memset(ciphertext, 0x00, SIZEOF(ciphertext));

aes128_ecb_encode_raw(plaintext, strlen(plaintext), ciphertext, key);

TAL_PR_NOTICE("AES_EN1: ");
TAL_PR_NOTICE("ciphertext: ");
for(i = 0; i<strlen(ciphertext); i++){
    TAL_PR_DEBUG_RAW("%02X ", ciphertext[i]);
}
TAL_PR_DEBUG_RAW("\r\n");

memset(decodetext, 0x00, SIZEOF(decodetext));
aes128_ecb_decode_raw(ciphertext, strlen(ciphertext), decodetext, key);

TAL_PR_NOTICE("AES_DE1: ");
TAL_PR_NOTICE("decodetext: %s", decodetext);

对应的日志打印如下：

你好，这段解密始终解出来的是乱码。能帮我看下什么情况吗？

Code: Select all


    BYTE_T data1[] ="b4046667e3c549673aa75369b605f342";
	BYTE_T datakey1[] ="6r4mq0ptoan2wf70";
	BYTE_T  outdata1[32] = {0};
    BYTE_T dedataget[32] = {0};
    BYTE_T cat[8];

    memset(dedataget,0x00,32);
	int ii = aes128_ecb_decode_raw(data1, strlen(data1), outdata1, datakey1);

    TAL_PR_INFO("ii;%d", ii);
    TAL_PR_INFO("data1;%s", data1);
    TAL_PR_INFO("strlen(data1);%d", strlen(data1));
    TAL_PR_INFO("outdata1;%s", outdata1);
    TAL_PR_INFO("outlen1;%d", outlen1);
    TAL_PR_INFO("strlen(outdata1);%d", strlen(outdata1));
    TAL_PR_INFO("datakey1;%s", datakey1);
    
	TAL_PR_INFO("outdata1;%s", outdata1);

"b4046667e3c549673aa75369b605f342"这段密文是我服务器下发下来的，密钥目前是固定"6r4mq0ptoan2wf70"。我需要先解密。但解密后就是乱码

1.你这个密文是字符串格式，你应该先将字符串转成Hex，然后再调用解密接口。如下图

2.另外 outdata1 是你申请的局部数组 不需要调用 aes_free_data(outdata1)进行额外的释放 。
