This paper deals with the novel approach to generate cubical key that symbolises the message and key in six‐face cubical structure. The cubical message is hybridised to generate the cipher in the encryption. Hybridisation of cubes is performed by using the XOR operation to the six‐face cubical original message and six‐face random sequence which is a part of Key‐Cube. https://foldlyers.shop/product-category/adapters-2-5-3-5-6-5mm-audio-cables/
