The data storage and information exchange activities digitally have risks and of course must be accompanied by information security. Various ways are done to protect data such as hiding data with steganography techniques or by encoding data with cryptographic techniques. If in general the steganography technique is done by inserting data into image, audio or video media, but in this study the data will be inserted or hidden into a text file as a media (cover message) to hide the data. While data security with cryptographic techniques is done by changing the data to be kept secret (plaintext) into encoded data (ciphertext) so that the data cannot be understood by people who do not have legality in the data. This research will implement a combination of the Bacon Cipher algorithm and the ROT128 algorithm which is the development of the ROT13 algorithm. The combination of the two algorithms in this research aims to get a stronger ciphertext so that it is more difficult to solve, by using a combination of these two algorithms it can optimize data security protection and to overcome the use of a single ciphertext which is comparatively weak.
