password Encryptoin Adn decrypt code to store database and r

Hi ,

Try below Code.


///

    /// Encrypts a given password and returns the encrypted data
    /// as a base64 string.
    ///

    /// An unencrypted string that needs
    /// to be secured.
    /// A base64 encoded string that represents the encrypted
    /// binary data.
    ///
    /// This solution is not really secure as we are
    /// keeping strings in memory. If runtime protection is essential,
    /// should be used.
    /// If
    /// is a null reference.
    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);
    }

    ///

    /// Decrypts a given string.
    ///

    /// A base64 encoded string that was created
    /// through the or
    /// extension methods.
    /// The decrypted string.
    /// Keep in mind that the decrypted string remains in memory
    /// and makes your application vulnerable per se. If runtime protection
    /// is essential, should be used.
    /// If
    /// is a null reference.
    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);
    }
