Unauthorized access and hacking are major issues for internet users, and numerous articles have been published on various approaches to solving this issue. This study proposes a novel method for encoding a hidden message within the text by combining text steganography and substitution cryptography. While steganography and cryptography can be used to protect data, neither is sufficient to provide better security as they can be broken by steganalysis and cryptoanalysis. Therefore, the terms "cryptography-stegano" should be combined for improved security. In this method, data is first encrypted using a substitution cryptography technique to produce the cypher text, which is then encrypted using text steganography to produce a more secure cypher text sent to the recipient. Contrary to popular belief, using image steganography and cryptographic methods is unnecessary for effective data encryption. The study shows that combining text steganography with cryptographic techniques is an excellent data security method. Additionally, other combinations, such as audio and video steganography, should also be considered for better security
