有没有同时懂 C#和 PHP 的大佬，帮看下 C#这段 aes 解密代码怎么翻译成 PHP 的好？

忘了那个方法加密前还有另一个处理函数，

var iv = string.Join("", key.ToCharArray().Reverse());
return AESDecrypt(cipherText, key, iv);
}

UnrealEngine OP @littleylv 不行，哦忘了那个方法加密前还有另一个处理函数，
字符串：FHPdyFl63G6xl/2rge/VQDkCW79tNG4cAFlnulZHj2shQ1+m1GeY++7MdTX/+KD9/13vDremaHrSMRlg1Wd/HA== KEY：1805412879961850 public static string AESDecrypt(string cipherText, string key) { var iv = string.Join("", key.ToCharArray().Reverse()); return AESDecrypt(cipherText, key, iv); } |

你是一点都不懂 C#还是一点都不懂 PHP 还是都不懂
我都方法告诉你了，就算你前面有个处理函数，不就是把 key 反转成 iv 吗 $input = base64_decode('FHPdyFl63G6xl/2rge/VQDkCW79tNG4cAFlnulZHj2shQ1+m1GeY++7 MdTX/+KD9/13vDremaHrSMRlg1Wd/HA=='); $key = '1805412879961850'; $iv = strrev($key); $decrypted = openssl_decrypt($input, 'AES-128-CBC', $key, OPENSSL_RAW_DATA, $iv); var_dump($decrypted); // 打印结果：string(49) "{"ActionId":1000,"SourceName":"YF37ZTOVEN6NRZO3"}" |
