The concept is easy and creative: get the data from the file, encode into base64, compact and encode into hexadecimal values, so get each three chunks of hexa values to compose the pixels colors that represents the file as an encoded PNG image so you can reverse and decode it later as the original file.
The concept is easy and creative: get the data from the file, encode into base64, compaqt and encode it into hexadecimal values, so get each six chunks of hexa values (ex: ff 12 d3) to compose the RGB pixels colors that represents the file as an encoded PNG image in such a way that you can reverse and decode it later as the original file.
