php 7.2 aes 128 ECB 加密

欢迎大家访问我的博客 www.kevink.club

---

php7.1 开始弃用mcrypt 加密 改为使用 openssl 加密

以下列出 aes ecb 加密 5.* 和 7.2及以上加密方式

php5.*
```

$key = 'Op2TlBNJ3drx71rF';
$string = '{"channel":"djqm","productId":"I19BR9","tranCode":"SPE20200804995150100991","userName":"陈先生","sex":"1011201","mobile1":"18633452430","idcardType":"1010901","idcardNum":"110101199003073773","startTime":"2020-08-04","endTime":"2021-08-04","dataType":"01","cardNum":"IQ990001006"}';

var_dump(aESEncryptRequest($key, $string));
    

function aESEncryptRequest($key, $string){
        $size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB);
        $pad = $size - (strlen($string) % $size);
        $input = $string . str_repeat(chr($pad), $pad);
        $td=mcrypt_module_open(MCRYPT_RIJNDAEL_128,'',MCRYPT_MODE_ECB,'');
        $iv = '';
        mcrypt_generic_init($td, $key, $iv);
        $data = mcrypt_generic($td, $input);
        mcrypt_generic_deinit($td);
        mcrypt_module_close($td);
        $data = bin2hex($data);
        return $data;
    }

```

加密方式使用ECB， 所以偏移量其实被忽略了，在加密过程中并没有涉及到IV.

加密结果一致。
