Question

在我们的项目中，我必须使用AES 128 CBC算法以及以下数据：

KEY =“abcdef0123456789abcdef0123456789”

IV =“00000000000000000000000000000000”

要加密的文字是

2〜1〜000024〜0910〜20130723092446〜T〜00002000〜USD〜F〜375019001012120〜0〜0〜000亿〜

预期的结果是

0D 58 35 AF EB EE 04 C6 DC 24 21 53 8D B7 C3 8A 12 83 97 0E B3 1F 21 A4 7D 2E 3C C6 23 D2 9E F0 46 12 79 C7 AC F9 3B 03 1B E2 B6 9C E4 5C 93 39 55 49 57 F2 9E F6 09 F0 19 EE C9 75 98 3A 03 B5 37 62 2D 7E 0F 19 6B E1 48 F1 C7 CB B8 8E 60 2A

结果文本的长度为160个字符。

我尝试使用了很多算法，但我的所有结果都不同。

您是否会使用自己的方法加密文本并使用预期结果进行验证？

您会粘贴结果吗？

这是我的测试：

$cipher = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, '');

$data_to_encrypt = "2~1~000024~0910~20130723092446~T~00002000~USD~F~375019001012120~0~0~00000000000~";
$key128 = "abcdef0123456789abcdef0123456789";
$iv = "0000000000000000"."0000000000000000";

echo "data_to_encrypt: ".$data_to_encrypt."<br/>";

if (($res = mcrypt_generic_init($cipher, $key128, $iv)) != -1)
{
    // PHP pads with NULL bytes if $cleartext is not a multiple of the block size.
    $cipherText = mcrypt_generic($cipher,$data_to_encrypt);
    mcrypt_generic_deinit($cipher);
    $data_encrypted = strtoupper(bin2hex($cipherText));
    echo "result encrypt: ".$data_encrypted."<br/>";
    echo "len: ".strlen($data_encrypted)."<br/>";
}

这是我的答案：

data_to_encrypt：2~1~000024~0910~20130723092446~T~000000~USD~F~375019001012120~0~0~00000000000~ 结果加密：C9A4E600BAC6FC4F2077FF62DDB5F9BEAB1C9C567A98E6B81373711A4BC0FFE1748F5E26886896AB87CD375567C5466E6A9F4C079AD19B592E080896BCFDB52324F342A9F94AE71FADB1F6820EB57F7B len：160

提前感谢您的帮助和时间。

Answer 1

这个C程序给出了正确的结果：

#include <stdio.h>
#include <openssl/aes.h>

int main()
{
unsigned char key[16] =     {0xab,0xcd,0xef,0x01,0x23,0x45,0x67,0x89,0xab,0xcd,0xef,0x01,0x23,0x45,0x67,0x89};
unsigned char iv[16] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
unsigned char plaintext[] = {
    '2','~','1','~','0','0','0','0','2','4','~','0','9','1','0','~',
    '2','0','1','3','0','7','2','3','0','9','2','4','4','6','~','T',
    '~','0','0','0','0','2','0','0','0','~','U','S','D','~','F','~',
    '3','7','5','0','1','9','0','0','1','0','1','2','1','2','0','~',
    '0','~','0','~','0','0','0','0','0','0','0','0','0','0','0','~',
};
unsigned char ciphertext[sizeof(plaintext)];
AES_KEY aes;
size_t i;

AES_set_encrypt_key(key,128,&aes);
AES_cbc_encrypt(plaintext,ciphertext,sizeof(plaintext),&aes,iv,AES_ENCRYPT);

for(i=0; i<sizeof(ciphertext); i++) {
    printf("%02x ", ciphertext[i]);
}
printf("\n");

return 0;
}

gcc -o test test.c -lcrypto

您的问题是在使用之前需要将密钥和IV字符串去除为字节。

首先，我要感谢向我发送一条建议的所有人，

现在，我与您分享我的问题的解决方案，

我希望它对任何人都有帮助，

<?php

function hex2bin($hex_string) {
    return pack('H*', $hex_string);
}

$data_to_encrypt = '2~1~000024~0910~20130723092446~T~00002000~USD~F~375019001012120~0~0~00000000000~';
$key = 'abcdef0123456789abcdef0123456789';
$iv = '0000000000000000';

$key = hex2bin($key);
$iv = hex2bin($iv);

$data_encrypted = bin2hex(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $data_to_encrypt, MCRYPT_MODE_CBC, $iv));
echo "Data encrypted: ".strtoupper($data_encrypted)."<br/>";
echo "Length: ".strlen($data_encrypted)."<br/>";

?>
