问题是我希望这两个代码返回相同的值,但结果不一样。提供的密钥和数据是相同的。
这是C#中的主要代码。结果是:JzhfuV7T8BI9NnYsFdHIDw==
public static RijndaelManaged GetCryptoTransform(string key)
{
string key_string64 = Convert.ToBase64String(Encoding.UTF8.GetBytes(key));
Console.WriteLine(key_string64);
RijndaelManaged aes = new RijndaelManaged();
aes.BlockSize = 128;
aes.KeySize = 256;
aes.Mode = CipherMode.CBC;
aes.Padding = PaddingMode.PKCS7;
byte[] keyArr = Convert.FromBase64String(key_string64);
byte[] KeyArrBytes32Value = new byte[keyArr.Length];
Array.Copy(keyArr, KeyArrBytes32Value, keyArr.Length);
byte[] ivArr = { 1, 2, 3, 4, 5, 6, 6, 5, 4, 3, 2, 1, 7, 7, 7, 7 };
byte[] IVBytes16Value = new byte[16];
Array.Copy(ivArr, IVBytes16Value, 16);
aes.Key = KeyArrBytes32Value;
aes.IV = IVBytes16Value;
return aes;
}
public static string Encrypt(string PlainText, string key)
{
var aes = GetCryptoTransform(key);
var encrypto = aes.CreateEncryptor();
byte[] plainTextByte = ASCIIEncoding.UTF8.GetBytes(PlainText);
byte[] CipherText = encrypto.TransformFinalBlock(plainTextByte, 0, plainTextByte.Length);
return Convert.ToBase64String(CipherText);
}
这是PHP代码,结果是:ztykbceGV0SZqh/MyBInXQ==
function aes128_cbc_encrypt($key, $data) {
$iv = "1234566543217777";
$keyString = base64_encode ( $key );
$padding = 16 - (strlen ( $data ) % 16);
$data .= str_repeat ( chr ( $padding ), $padding );
return mcrypt_encrypt ( MCRYPT_RIJNDAEL_128, $keyString, $data, MCRYPT_MODE_CBC, $iv );
}
答案 0 :(得分:1)
在C#中,IV是一个整数字节数组,在PHP中,IV是一个字符串,它们不一样。
Ex:整数字节1
的值为0x01,字符"1"
的值为0x31。
