I have a problem (server side) when i encrypt data from a client and i send to webserver with Post Method.
i Use this Method to Encrypt from a C# Client
public string Encrypt3DES(string strString)
{
DESCryptoServiceProvider DES = new DESCryptoServiceProvider();
DES.Key = Encoding.GetBytes(this.Key);
DES.Mode = CipherMode.ECB;
DES.Padding = PaddingMode.Zeros;
ICryptoTransform DESEncrypt = DES.CreateEncryptor();
byte[] Buffer = encoding.GetBytes(strString);
return Convert.ToBase64String(DESEncrypt.TransformFinalBlock(Buffer, 0, Buffer.Length));
}
When i send ecrypted String to PHP if there was a + in that string, php read it with a blank space. If instead there'isnt any '+' i haven't any problem.
For Example this is a Encrypted String 4aY+na42iaPg+aep== in C# when i read in php it's 4aY a42iaPg aep== so if i decrypt if dont match with the correct word.
i use this script to start read method post
if (isset($_POST['doConvalid'])){
if ($_POST['doConvalid']=='Convalid')
{
foreach($_POST as $keys => $values) {
$data[$keys] =($values); // post variables are filtered
}
$cheking=$data['check'];
echo("Show checking = $checking"); //Here i read string with blank space instead +
Is there a way to fix it?
