Steganography is an important method utilized by malicious and genuine activists, hackers, and security engineers to carry out secret communication by hiding sensitive messages/information under cover of a media or other information. This process of hiding information within another requires multiple complicated algorithms, techniques, and methodologies. The current manuscript briefly touches upon steganography and why it is called the art of invisible or secret communication, along with an example through coding of one of its types in Python. The manuscript also describes some of the multiple techniques and methodologies that are part of and help generate different steganograms for a different type of information or media.
