Hi,
I'm not sure if this is the right place to post this, I have some decryption
routines that use mcrypt that I need to decrypt in .NET, does anyone know
how why I cant get this to work?
---- PHP
$mcryptSize = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB);
$mcryptIV = mcrypt_create_iv($mcryptSize, MCRYPT_RAND);
$mcryptData = pack("H*", $data);
$decryptData =
mcrypt_decrypt(MCRYPT_RIJNDAEL_128,$key,$mcryptData,MCRYPT_MODE_ECB,$mcryptIV);
---------
$decryptData should be 2048 in size. Here's my C# converted bits:
------------- C#
RijndaelManaged rj = new RijndaelManaged();
rj.Mode = CipherMode.ECB;
rj.Key = ASCIIEncoding.ASCII.GetBytes(KEY);
rj.KeySize = 128;
rj.GenerateIV();
rj.Padding = PaddingMode.Zeros;
ICryptoTransform trans = rj.CreateDecryptor(rj.Key, rj.IV);
byte[] Buffer = Convert.FromBase64String(DATA);
string dataD =
ASCIIEncoding.ASCII.GetString(trans.TransformFinalBlock(Buffer,0,
Buffer.Length));
-------------
However the length is 3017
Any ideas?
Thanks,
Sym
