public string Encrypt(string plainText)
{
if (plainText == null) throw new ArgumentNullException("plainText");

//encrypt data
var data = Encoding.Unicode.GetBytes(plainText);
byte[] encrypted = ProtectedData.Protect(data, null, Scope);

//return as base64 string
return Convert.ToBase64String(encrypted);
}

public string Decrypt(string cipher)
{
if (cipher == null) throw new ArgumentNullException("cipher");

//parse base64 string
byte[] data = Convert.FromBase64String(cipher);

//decrypt data
byte[] decrypted = ProtectedData.Unprotect(data, null, Scope);
return Encoding.Unicode.GetString(decrypted);
}

 public string Encrypt(string plainText)     {         if (plainText == null) throw new ArgumentNullException("plainText");          //encrypt data         var data = Encoding.Unicode.GetBytes(plainText);         byte[] encrypted = ProtectedData.Protect(data, null, Scope);          //return as base64 string         return Convert.ToBase64String(encrypted);     }

 public string Decrypt(string cipher)     {         if (cipher == null) throw new ArgumentNullException("cipher");          //parse base64 string         byte[] data = Convert.FromBase64String(cipher);          //decrypt data         byte[] decrypted = ProtectedData.Unprotect(data, null, Scope);         return Encoding.Unicode.GetString(decrypted);     }
