Hiding Secret Messages in Images (Steganography)

In this video i show you how you can use java to hide hidden messages in images aka steganography. This was part of what i learned for my end of year programming project as part of my cybersecurity degree apprenticeship. This is a more simple version of steganography a technique that secret services and criminals use alike to communicate. This technique takes the ascii bytes and puts them into a byte array this is then appended to the end of the jpg file and does not change how the pixels look.
