copied!<p>I'm trying to achive the same DES encription that I've in an C# code but in PHP.</p> <p>The C# code looks like the following:</p> <pre><code>public static string EncriptarCadena(string strEncriptar) { DESCryptoServiceProvider provider; MemoryStream stream; CryptoStream stream2; string str2; string str = "29393651"; byte[] buffer2 = new byte[] { 0x45, 50, 0xa5, 0x18, 0x67, 0x58, 0xac, 0xba }; byte[] bytes = new byte[0]; try { bytes = Encoding.UTF8.GetBytes(str.Substring(0, 8)); provider = new DESCryptoServiceProvider(); byte[] buffer = Encoding.UTF8.GetBytes(strEncriptar); stream = new MemoryStream(); stream2 = new CryptoStream(stream, provider.CreateEncryptor(bytes, buffer2), CryptoStreamMode.Write); stream2.Write(buffer, 0, buffer.Length); stream2.FlushFinalBlock(); str2 = Convert.ToBase64String(stream.ToArray()); } catch (Exception) { str2 = ""; } finally { provider = null; stream = null; stream2 = null; } return str2; } </code></pre> <p>And the code that I've done till now in PHP is the following:</p> <pre><code>function encrypt($string) { //Key $key = "29393651"; $ivArray=array( 0x45, 50, 0xa5, 0x18, 0x67, 0x58, 0xac, 0xba ); $iv=null; foreach ($ivArray as $element) $iv.=CHR($element); echo "Key: $key IV: $iv<br>"; $encrypted_string = mcrypt_encrypt(MCRYPT_DES, $key, $string, MCRYPT_MODE_CBC, $iv); return base64_encode($encrypted_string); } </code></pre> <p>But I can't find where is the problem, as they don't give the same result for the same input.</p> <p>Any help will be very welcome :)</p>
