                                throws java.security.GeneralSecurityException
        Helper function to encrypt ByteBuf with the given key. When useFixedIv is true, don't use a random iv byte array, using a all zero byte array instead. Only set it to be true in test.
        Parameters:
        toEncrypt - ByteBuf that needs to be encrypted
        key - the secret key (of type T) to use to encrypt
        iv - If null, will create a random byte array serve as iv bytes.
        Returns:
        the ByteBuf containing the encrypted content. Ensure the result has all the information like the IV along with the encrypted content, in order to decrypt the content with a given key
        Throws:
        java.security.GeneralSecurityException
