Here is 2 simple functions for Password Encryption and Decryption.
using System.Security.Cryptography;
private string EncryptedPassword(string ValueToEncrypt)
{
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, cryptObj.CreateEncryptor(KEY_128,
IV_128), CryptoStreamMode.Write);
StreamWriter sw = new StreamWriter(cs);
sw.Write(ValueToEncrypt);
sw.Flush();
cs.FlushFinalBlock();
ms.Flush();
return Convert.ToBase64String(ms.GetBuffer(), 0, (int)ms.Length);
}
private string DecryptedPassword(string ValueToDecrypt)
{
byte [] buf = Convert.FromBase64String(ValueToDecrypt);
MemoryStream ms = new MemoryStream(buf);
CryptoStream cs = new CryptoStream(ms, cryptObj.CreateDecryptor(KEY_128,
IV_128), CryptoStreamMode.Read);
StreamReader sr = new StreamReader(cs);
return sr.ReadToEnd();
}
