I have a Security class that Encode and Decode string, but when I try do decode - something going wrong.
Here is my Security class:
class Security
{
public static String encrypt(String imput, String key)
{
String cipherText;
var rijndael = new RijndaelManaged()
{
Key = Encoding.Unicode.GetBytes(key),
Mode = CipherMode.ECB,
BlockSize = 128,
Padding = PaddingMode.Zeros,
};
ICryptoTransform encryptor = rijndael.CreateEncryptor(rijndael.Key, null);
using (var memoryStream = new MemoryStream())
{
using (var cryptoStream = new CryptoStream(memoryStream, encryptor, CryptoStreamMode.Write))
{
using (var streamWriter = new StreamWriter(cryptoStream))
{
streamWriter.Write(imput);
streamWriter.Flush();
}
cipherText = Convert.ToBase64String(memoryStream.ToArray());
}
}
return cipherText;
}
public static String decrypt(String imput, String key)
{
byte[] data = Convert.FromBase64String(imput);
String decrypted;
using (RijndaelManaged rijAlg = new RijndaelManaged())
{
rijAlg.Key = Encoding.UTF8.GetBytes(key);
rijAlg.Mode = CipherMode.ECB;
rijAlg.BlockSize = 128;
rijAlg.Padding = PaddingMode.Zeros;
ICryptoTransform decryptor = rijAlg.CreateDecryptor(rijAlg.Key, null);
using (MemoryStream msDecrypt = new MemoryStream(data))
{
using (CryptoStream csDecrypt = new CryptoStream(msDecrypt, decryptor, CryptoStreamMode.Read))
{
using (StreamReader srDecrypt = new StreamReader(csDecrypt))
{
decrypted = srDecrypt.ReadToEnd();
}
}
}
}
return decrypted;
}
}
In program.cs:
String A = Security.encrypt("text", "1234567891234567");
A = Security.decrypt(A, "1234567891234567");
Finaly it return something like that: �%����;\0�\a��f6 , but I need original string. Where I made a mistake?
